Installation position Front side: High-voltage section with protection class IP00. Rear side: Low-voltage section with protection class IP20. The vacuum contactor 3TM can be installed in four positions. 1) 2) 3) 4) *) Fig. 5 Wall mounting, vertical Supine position, horizontal Wall mounting, vertical, rotated 180 Suspended, with reduced parameters (after consultation with manufacturer) Observe distance to high-voltage and grounded components! Installation position High-voltage section The high-voltage section consists of individual, autonomous pole shells, which can receive the correspondingly dimensioned vacuum interrupters. This makes variable distances between the pole centres possible (120 mm and 150 mm). Solenoid actuator The vacuum interrupters are actuated by a common solenoid actuator. This solenoid actuator has a very low holding capacity in continuous operation. The vacuum interrupters work synchronously in the same direction. The solenoid actuator and the shunt release of the vacuum contactor 3TM can be actuated with AC or DC. Vacuum contactors 3TM work according to a defined closing and opening time, which can be configured and extended by an additional closing and opening delay. Both delay values are independent of each other and are added to the closing and opening times. Electronic controller The electronic controller controls the supply of energy to the solenoid actuator on closing. The closing current is controlled to a specified level. The current is switched to the holding current after a specified time. The holding current reduces the vacuum contactor's energy supply during operation. The voltage supply of the magnetic unlatching is not affected. The customer is to deal with the signal control. The maximum signal duration is to be observed, since the shunt release solenoid only has a limited continuous current strength of 500 ms. The inrush current (peak) is dependent on the control voltage. Control voltage terminals 9229 0090 176 0A 2017-12-07 The electronic controller has terminals for the following: * the control voltage A1/A2, as well as independent thereof * the supply voltage for the magnetic unlatching E1/E2 (optional). 15 Description Fig. 6 Terminals A1/A2 and optionally E1/E2 of the electronic controller The electronic controller also allows the configuration of additional closing and opening delays. If no configuration is selected, only the natural closing and opening time of the switching device is active. Configuration is done via a 6-pin DIP switch S2 on the electronics assembly (matrix, see Chapter "Configuring the controller", p. 48). Auxiliary switch Mechanical closing latching The auxiliary switches are mounted on the side of the operating mechanism box and are not wired. The wiring is carried out on the customer's premises using screw terminals. (Applies only to vacuum contactors with closing latching) When the vacuum contactor is closed, the mechanical closing latching is activated. The solenoid actuator is held and automatically separated from the voltage supply once the latching position is reached. Switching in the de-energised holding mode (control voltage circuit A1/A2) is carried out automatically via the electronic controller.

The remote tripping is carried out via the electromagnetic shunt release Y1 (9). If manual unlatching (emergency-stop) via the push rod or draw bar is not available, the shunt release Y1 can be carefully manually actuated from the rear side of the vacuum contactor in a de-energised state and for test purposes (see details in Fig. 8). Manually operated unlatching (emergency-stop) is performed with a push rod or draw bar (12, 15) with approx. 30 N. The customer is to mount M4 threaded rods for the push rod or draw bar with fitting end pieces or other suitable terminators. Tightening torque 3 0.5 Nm. Subsequent ordering If no latching or unlatching is available but is planned for backfit, the following modules can be subsequently ordered and mounted: * * Mechanical closing latching with shunt release Y1 Manually operated unlatching mechanical system (emergency-stop) with push rod or draw bar See chapter "Mounting the mechanical closing latching (optional) and manual unlatching (optional)", p. 35.

Fig. 44 Busbars mounted at an angle Fig. 45 Busbars mounted in a straight position Corresponding to the rated current strength, use M10 screws and nuts - strength class 8.8 - and the appropriate spring elements and washers for connection of the busbars. Tightening torque M10: 48 4 Nm Tightening torques apply to greased threads only. Attach the busbars or flexible braid tension-free and torsion-free to the upper and lower terminals. Further steps for connecting the prime conductors are not described herein and are performed by the customer. 40 9229 0090 176 0A 2017-12-07 Operation Operation DANGER Danger to life due to electric shock! Electric shock can result in death, serious injury, or considerable material damage. * Do not touch live parts! * Ensure that the vacuum contactor is operated only by qualified personnel who are familiar with the operating instructions and observe the warning notices! * Check through all of the items on the checklist and ensure correct functioning before commissioning! Commissioning Dielectric tests To test the vacuum contactor in a state without supply and control voltage, it is necessary to short-circuit and earth the terminals for supply and control voltage A1/A2 and, if applicable, E1/E2 for the supply voltage for magnetic unlatching. Subsequently the following tests can be performed: * Dielectric test of the main circuit as per DIN EN 62271-1 (Chapter 7.1.) and * Dielectric test of the auxiliary and control circuits as per DIN EN 62271-1 (Chapter 7.2.4.). Before commissioning, check the following points to ensure that the vacuum contactor is functioning faultlessly. Checklist Notes Does the information on the rating plate match the order data (see p. 17)? Ensure correct operating voltage. Check the control feed voltage and the performance data of the low-voltage network are correct. If necessary, clean the vacuum contactor (details on this in section "Cleaning" on p. 45). Check that a stable supply voltage is applied with a short-time load exceeding 1.7 kW, otherwise the switching device will not reach the closing position or reach it with a delay. If necessary, check the functionality of the manual unlatching (EMERGENCY STOP) in conjunction with the switch cabinet door. Check that screw connections are tightened securely. Check the plug connections for a firm seat. Check the functioning of the auxiliary switches. If necessary, check and adjust the customer's devices. If the DIP switch setting has been changed by the customer: Check the correct setting of the DIP switch on the electronic controller (see p. 48). Check changed MLFB entries on the rating plate. Continued on the next page 9229 0090 176 0A 2017-12-07 41 Operation Checklist Notes Check the unlatching. If manual unlatching (emergency-stop) via the push rod or draw bar is not available, the shunt release (-Y1) can be manually actuated in a de-energised state and for test purposes (see Fig. 8 on p. 16). Test the electric switching repeatedly before the vacuum contactor is put into operation in the network. WARNING Do not commission the vacuum contactor if there are malfunctions. If the malfunctions or damage cannot be remedied, contact a sales representative or Siemens Service and, if necessary, send back the vacuum contactor in the original packaging. Troubleshooting Incident Troubleshooting Vacuum contactor does not respond * Check the DIP switch S2 position and reset if necessary (see matrix Fig. 52). Closing is blocked * Send it back to the manufacturer1). Failure of the control voltage Ua * * * Check the connectors on the electronic controller for a firm seat. Check the cable connection to the connectors. If a new vacuum contactor is installed, use only the connectors provided in the accessory pack (see p. 36). Defective shunt release * Order a spare part and mount according to the supplied instructions. Vacuum contactor does not return to the starting position or the initial state * * Inspect the contact welding and remedy by means of no-load switchings. For existing closing latching, actuate the manual unlatching (no-load switching permissible). Vacuum contactor does not latch * Send it back to the manufacturer1). Manual unlatching is blocked * Check that the unlatching mechanism is attached to the coupling point and reattach with max. 4 Nm. While doing so, prevent the threaded rod from twisting. 1) Complete vacuum contactor First closing operation If all functions have been checked and are OK, switch on the high voltage while observing all of the safety regulations and operational requirements. 42 9229 0090 176 0A 2017-12-07 Maintenance Maintenance Maintenance and servicing DANGER Risk of injury! Working on the opened and closed vacuum contactor can lead to fatal injuries. * Before beginning maintenance work, note the 5 safety rules for high-voltage equipment specified in EN 50110-1, namely: - Isolate from the power supply - Secure against reclosing - Verify that the equipment has been de-energised - Earth and short-circuit - Cover or cordon off neighbouring live parts * Open the vacuum contactor by hand and operate the mechanical unlatching if necessary. This ensures that the vacuum contactor is open. * The vacuum contactor is to be taken out of the system/switch cabinet for maintenance work. Inspections The following work is to be carried out as part of the regular inspections: * * * * * * * * * Checking the switching stroke of vacuum interrupters Visual inspections during storage, see "Storage" on p. 7 Visual inspections during operation Screws and terminals are firmly attached Earthing connection firmly established and not damaged Labelling is clearly legible Insulation capacity not hampered by deposits, see "Cleaning" on p. 45 Check the limit dimension of switching stroke of the vacuum interrupters, depending on the mechanical and electrical strain or switching frequency, every 100,000 switchings or once a year. See "Checking the switching stroke of vacuum interrupters" on p. 43 Regular function check of closing latching and then unlatching with manual trip, see "Mechanical closing latching", on p. 16 Measurement of conductance of auxiliary switch contacts. Reliable switching of the 3TM vacuum contactor is only ensured if the switching stroke of the vacuum interrupters is not below the minimum of 3.5 mm and does not exceed the maximum of 7.5 mm. The switching stroke can vary depending on current, elapsed service life, and switching frequency. If the value goes below the limit, arcing between the contacts in the vacuum interrupter can negatively affect opening. Correct functioning of the bellows for the vacuum interrupters can be compromised if the limit is violated. The switching stroke must be regularly checked. If the limit is reached, the switching stroke can be readjusted once. If the limit is then exceeded again, the vacuum contactor must be replaced. If the specified limits for mechanical or electrical service life are reached, the vacuum contactor must be replaced and readjustment is not permissible. 9229 0090 176 0A 2017-12-07 43 Maintenance Limit Fig. 46 OPEN switch position Fig. 47 CLOSED switch position Limit: a - b = min. 3.5 mm or max. 7.5 mm a b Adjusting the switching stroke of vacuum interrupters OPEN switch position CLOSED switch position Torsional loading of the draw bar (40) of the vacuum interrupters (3) must be prevented.
