Installation
■ Tools
A flat-blade screwdriver should be used to mount the cables.
Applicable Screwdriver
● Flat-blade, Parallel-tip, 2.5 mm diameter (3.0 mm max.)
● Flat-blade, Parallel-tip
2.5 dia. (3.0 mm max.)
● Flat-blade, Flared-tip
Cannot be used.
Examples: FACOM AEF.2.5 × 75E (AEF. 3 × 75E)
*Chamfering the tip of the driver improves insertion when used as an exclusive tool.

■ Applicable Wires
Applicable Wire Sizes
0.2 to 1.5 mm2, AWG24 to AWG16
Applicable Wire Type
Solid wires, stranded wires, flexible wires, or wires with ferules can
be used.
(See note 1.) < 2.2 ≤ Diameter D (mm) ≤ 3.2 (3.5: see note 2.)
Conductor diameter d (mm) or length of sides a and b (mm) ≤ 1.9
Note: 1. If the outer diameter D of the wire is less than 2.2 mm and
the exposed conductor length is less than 8 mm potentially
bad connection might occur in case wire is pushed to far inside. Please see following drawing.
Wires with Ferules
2. If the outer diameter D of the wire exceeds 3.2 mm, it might
be difficult to use double wiring.

Precautions
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 socket and result in a short-circuit.
• Do not insert two or more wires in the hole. Wires may come in
contact with the spring causing a temperature rise or be subject to
sparks. (There are two wiring holes for each terminal.)
• Insert the screwdriver along the hole wall as shown below.
Screwdriver
• If lubricating liquid, such as oil, is present on the tip of 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
possible to connect cables properly if the screwdriver is inserted
incorrectly.
General Precautions
• Use the clip to prevent relays floating or falling out of the socket.
• Do not use the product if it has been dropped on the ground. Drop-
ping 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 cleansing 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 dispose of the product in fire.
Removing from Mounting Rail
To remove the socket from the mounting rail, insert the tip of screwdriver in the fixture rail, and move it in the direction shown below.
