## Safety Precautions 

- Turn off power to the relay and the socket before starting installation, removal, wiring, maintenance, and inspection of the relays. Failure to turn power off may cause electrical shock or fire hazard. 

- Use wires of the proper size to meet the voltage and current requirements. 

- Make sure that relay and output equipment are wired correctly. Incorrect wiring causes overheat resulting in possible fire hazard. 

- Prevent metal fragments and pieces of wire from dropping inside the socket. Ingress of such fragments and chips may cause fire hazard, damage, or malfunction. 

## Instructions 

## Installing relays 

The relay is installed on the socket using the release lever. Leaf spring is not necessary. 

## Rail Mounting and Removing 

Do not mount or remove the socket in cold temperature (below –20°C), otherwise the socket may be damaged.

## Installing relays 

1. Unlock the release lever by pulling down as shown with arrow ➀. 

2.  Press the relay against the socket as shown with arrow ➁. Make sure that the relay is firmly in place. 

3.  Confirm that the relay is securely installed in the socket. When installed properly, the relay and the socket look as shown in ➂

## Caution 

**==> picture [122 x 115] intentionally omitted <==**

## Removing the relay 

- ➀  Lightly press the relay to prevent it from falling off. 

- ➁  Pull down the release lever to the direction shown by the arrow until it touches the socket. Pull down further, and the lever will be detached from the socket. 

## Caution 

Make sure that wire or finger is not caught between the release lever and socket. 

Because release lever is removable, make sure not to apply excessive force. Otherwise the relay may fall and result in damage. 

## Panel Mounting 

Insert the anti-rotation projection into the anti-rotation hole. Mount the socket onto the panel using M3 screws (not provided). Use a screwdriver with diameter of ø5.5mm maximum. 

## Mounting Hole Layout

Tighten the mounting screws to a torque of 1.0 N·m maximum. Tightening with higher torque will damage the socket. 

The round rib projecting from the socket bottom prevents rotation when the socket is mounted on the panel directly. Ensure to insert the rib into the anti-rotation hole, otherwise the socket may be damaged. 

## Removing the Release Lever 

**==> picture [69 x 56] intentionally omitted <==**

Pull down the release lever to the direction shown by the arrow until it touches the socket. Pull down further, and the release lever will be detached from the socket. 

## Caution 

Make sure that the relay has been removed from the socket before removing the release lever. If the release lever is removed when the relay is installed on the socket, the relay may fall out. 

Ensure that the relay is installed in the socket completely.
