Note: 1. If the overall diameter of the wire is less than 2.2 mm,
do not insert the wire past the conductor. Refer to the
following diagrams.

Use the following wiring procedure.
1. Insert the specified screwdriver into the release hole located
beside the wire connection hole where the wire is to be
inserted.
2. Insert the exposed conductor into the wire connection hole.

Precautions
J
PRECAUTIONS FOR CONNECTION
Do not move the screwdriver up, down, or from side to side while
it is inserted in the hole. Doing so may cause damage to internal
components (e.g., deformation of the coil spring or cracks in the
housing) or cause deterioration of insulation.
Do not insert the screwdriver at an angle. Doing so may break
the side of the socket and result in a short--circuit.
J
GENERAL PRECAUTIONS
Use the clip to prevent relays from floating or falling out of the
socket.
Do not use the product if it has been dropped on the ground.
Dropping the product may adversely affect performance.
Confirm that the socket is securely attached to the mounting
track before wiring. If the socket is mounted insecurely it may fall
and injure the operator.
Ensure that the socket is not charged during wiring and
maintenance. Not doing so may result in electric shock.
Do not pour water or cleaning agents on the product. Doing so
may result in electric shock.
Do not use the socket in locations subject to solvents or alkaline
chemicals.
Do not use the socket in locations subject to ultraviolet light (e.g.,
direct sunlight). Doing so may result in markings fading, rust,
corrosion or resin deterioration.
Do not insert two or more wires in the hole. Wires may come in
contact with the spring causing a termperature rise or may be
subject to sparks. (There are two wiring holes for each terminal.)
Do not dispose of the product in fire.
J
REMOVING FROM MOUNTING RAIL
To remove the socket from the mounting rail, insert the tip of the
screwdriver in the fixture rail and move it in the direction shown
below.
Insert the screwdriver along the hole wall as shown below.
If lubricating liquid, such as oil, is present on the tip of the
screwdriver, the screwdriver may fall out resulting in injury to the
operator.
Insert the screwdriver into the bottom of the hole. It may not be
possilble to connect cables properly if the screwdriver is inserted
incorrectly.
