SSR with Failure Detection Function

G3PC

Precautions

Refer to the Technical Information for SSRs (Cat. No. J137) for gen-

eral precautions.

I Correct Use

Before Actual Operation

1. In actual operation, the G3PC may cause accidents that were

unforeseeable at the theoretical stage. Therefore it is necessary

to test the G3PC under a variety of conditions that are possible.

As for the characteristics of the G3PC, it is necessary to consider

the differences between G3PC Units.

2. The ratings in this datasheet are for testing in a temperature

range of 15 to 30

°C, a relative humidity range of 25% to 85%, and

an atmospheric pressure range of 88 to 106 kPa. When testing

operation, it is necessary to confirm correct operation not only

with the actual load that will be used, but also at the same ambi-

ent conditions as for actual operation.

Mounting Method

DIN Track Mounting

When mounting to a DIN track, mount the G3PC until it clicks into

place, otherwise it become loose during use and fall. Fix both ends

with end plates.

Panel Mounting

When mounting directly to a panel, observe the following conditions:

Screw diameter: M4

Tightening torque: 0.98 to 1.47 N·m

Note: Use the G3PC at a load current of 50% of the rated load current

when it is mounted horizontally.

Side-by-side Mounting

Note: Use the G3PC at a load current of 80% of the rated load current

when it is mounted side-by-side.

Wiring

• When using crimp terminals, observe the terminal clearances

shown below.

• Be sure that all lead wires are of a thickness appropriate for the

current.

• The output terminals are charged, and touching them may result in

electric shock, even when the G3PC is OFF. Separate the outputs

from the power supply by installing a circuit-breaker at a higher

level in the circuit.

Tightening Torque

Be sure to tighten the screws to the specified torques given below.

Not doing so may result in malfunction.
