Safety Precautions

Be sure to read the precautions for All PushButton Switches in the website at:http://www.ia.omron.com/.

Indication and Meaning for Safe Use

!CAUTION

Mounting

• Always make sure that the power is turned OFF before wiring the

Switch. Also, do not touch the terminals or other current-carrying

ports while power is being supplied. Electric shock may occur.

• Do not tighten the mounting ring more than necessary using tools

such as pointed-nose pliers. Doing so will damage the mounting

ring. The tightening torque is 0.98 to 1.96 N·m.

• Recommended panel thickness: 1 to 5 mm.

• When mounting the caps after changing the LED or the caps,

tighten the caps at a tightening torque of 0.49 tp 0.78 N·m.

Mounting the Lock Plate

1. Confirm that the lever on the Mounting Latch is on the side where

the Operation Unit is secured and then insert the protrusion on the

Lock Plate into the hole in the lever on the Mounting Latch.

2. Press the hole on the Lock Plate onto the protrusion on the

Mounting Latch until it clicks into place.

Precautions

for Safe Use

Supplementary comments on what to do

or avoid doing, to use the product safely.

Do not apply a voltage exceeding the rated voltage across

the incandescent lamp terminals.

The lamp may be destroyed and the operation unit may fly

out.

If the Operation Unit is separated from the Socket Unit, the

equipment will not stop, creating a hazardous condition.

Secure the lever on the Socket Unit by using the

A22Z-3380 Lock Plate so that the Operation Unit cannot

be easily separated from the Socket Unit.
