Safety Precautions
Refer to the “Precautions for All Relays” and “Precautions for All Relays with Forcibly Guided Contacts”.
!CAUTION
Failure Detection for Slow-starting Power Supply
When using a power supply with a long start-up time, if power is
switched on while input has been closed the internal circuits will
detect a power voltage error and the product will not operate. Apply
the voltage to the product once the voltage has reached its rated level.
Installation
The G9SB can be installed in any direction.
Wiring
•Use the following to wire the G9SB.
Stranded wire: 0.2 to 2.5 mm2
Solid wire: 0.2 to 2.5 mm2
•Tighten each screw to a torque of 0.5 to 0.6 N·m, or the G9SB may
malfunction or generate heat.
•External inputs connected to T11 and T12 or T21 and T22 of the
G9SB must be no-voltage contact inputs.
•Strip the wires by 7 mm max.
Mounting Multiple Units
When mounting multiple Units close to each other, the rated
current will be 3 A. Do not apply a current higher than 3 A.
Connecting Inputs
If using multiple G9SB models, inputs cannot be made using the
same switch. This is also true for other input terminals.
Ground Shorts
A positive thermistor (TH) is built into the G9SB internal circuit to
detect ground shorts and shorts between channels 1 and 2. When
such faults are detected, the safety outputs are interrupted. (Only
G9SB-2002-@/3012-@ is able to detect shorts between channels 1
and 2.)
If the short breakdown is repaired, the G9SB automatically
recovers.
Note: In order to detect earth short breakdowns, connect the minus
side of the power supply to ground.
Resetting Inputs
When only channel 1 of the 2-channel input turns OFF, the safety
output is interrupted. In order to restart when this happens, it is
necessary to turn OFF and ON both input channels. It is not
possible to restart by resetting only channel 1.
Durability of Contact Outputs
Relay with Forcibly Guided Contact durability depends greatly on the
switching condition. Confirm the actual conditions of operation in
which the Relay will be used in order to make sure the permissible
number of switching operations.
When the accumulated number of operation exceeds its permissible
range, it can cause failure of reset of safety control circuit. In such
case, please replace the Relay immediately. If the Relay is used
continuously without replacing, then it can lead to loss of safety
function.
Applicable Safety Category (EN954-1)
G9SB-200@-@/301@-@ meet the requirements of Safety Category 4
of the EN954-1 standards when they are used as shown in the
examples provided by OMRON. Relays may not meet the standards
in some operating conditions. The G9SB-3010 can be applied to
Safety Category 3 of the EN954-1 using double breaking.
The applicable safety category is determined from the whole safety
control system. Make sure that the whole safety control system meets
EN954-1 requirements.
Certified Standards
The G9SB-200@-@/3010/301@-@ conforms to the following
standards.
•EN standards, certified by TÜV Rheinland:
EN954-1
EN60204-1
•Conformance to EMC (Electromagnetic Compatibility), certified by
TÜV Rheinland
EMI (Emission): EN55011 Group 1 Class A
EMS (Immunity): EN61000-6-2
•UL standards: UL508 (Industrial Control Equipment)
•CSA standards: CSA C22.2 No. 14 (Industrial Control Equipment)
•CCC Certification: GB14048.5
Turn OFF the G9SB before wiring the G9SB. Do not touch
the terminals of the G9SB while the power is turned ON,
because the terminals are charged and may cause an
electric shock.
