Safety Precautions

■Precautions for Safe Use

Observe the following items to ensure the safe use of this product.

Environmental Precautions

•Store the H3AM within the specified ratings. If the H3AM has been

stored at temperatures –10°C or lower, let it stand for 3 hours or

longer at room temperature before turning ON the power supply.

•Use the H3AM within the specified ratings for operating

temperature and humidity.

•Do not operate the H3AM in locations subject to sudden or extreme

changes in temperature, or locations where high humidity may

result in condensation.

•Do not use the H3AM in locations subject to vibrations or shock.

Extended use in such locations may result in damage due to stress.

•Do not use the H3AM in locations subject to excessive dust,

corrosive gas, or direct sunlight.

•Install the H3AM well away from any sources of static electricity,

such as pipes transporting molding materials, powders, or liquids.

•Do not use organic solvents (such as paint thinner or benzine),

strong alkaline, or strong acids because they will damage the

external finish.

Usage Precautions

•Install a switch or circuit breaker that allows the operator to

immediately turn OFF the power, and label it to clearly indicate its

function.

•Be sure to wire the terminals correctly.

•Do not install input lines in the same duct or conduit as power

supply or other high-voltage lines. Doing so may result in

malfunction due to noise. Separate the input lines from high-

voltage lines.

•Internal elements may be destroyed if a voltage outside the rated

voltage is applied.

•Maintain voltage fluctuations in the power supply within the

specified range.

•Use a switch, relay, or other contact so that the rated power supply

voltage will be reached within 0.1 s. If the power supply voltage is

not reached quickly enough, the H3AM may malfunction or outputs

may be unstable.

■Precautions for Correct Use

Changing Switch Settings

Be sure to adjust the time unit selector and instantaneous or time-

limit output selector for R2 relay only before the Timer is turned ON,

otherwise the Timer may be damaged or malfunction.

Be sure to set the time only when Timer has stopped, otherwise the

Timer may malfunction.

Setting the Operating Time

Do not turn the time setting knob beyond the permissible range. If a

precise time setting is required, check the operation of the Timer in

trial operation before the Timer is put in actual operation.

Before using the H3AM-NSR, apply voltage between terminals 9 and

10 to reset the operation.

When changing the setting time of the H3AM-NSR to a longer time

value, be sure to apply voltage between terminals 9 and 10 during

the change.

Others

When mounting the Timer on a panel, evenly tighten the Timer to a

specified torque. If the Timer using waterproof packing is tightened to

a torque other than the specified value, required waterproof

properties will not be achieved.

If the Timer is mounted on a control panel, dismount the Timer from

the control panel or short-circuit the circuitry before carrying out a

voltage withstand test between the electric circuitry and non current-

carrying metal part of the machine, in order to prevent the internal

circuitry of the TImer from damage.

The internal elements may be damaged if a voltage other than the

rated supply voltage is applied.

■Precautions for EN61812-1

Conformance

The H3AM as a built-in timer conforms to EN61812-1 provided that

the following conditions are satisfied:

The output section of the H3AM is provided only with basic isolation.

The H3AM itself is designed according to the following:

•Overvoltage category III

•Pollution degree 2

On the above basis:

Operation parts on the front and bottom: Reinforced isolation

With clearance of 5.5 mm and creepage distance of 5.5 mm at 240

VAC

Output: Basic isolation

With clearance of 3.0 mm and creepage distance of 3.0 mm at 240

VAC
