Safety Precautions
Instructions
• In order to avoid electric shock or fire, turn the power off before
installation, removal, wiring, maintenance, or inspection of the
switch.
• If relays are used in the circuit between the interlock switch
and the load, use only safety relays, since welded or sticking
contacts of standard relays may invalidate the functions of the
interlock switch. Perform a risk assessment and make a safety
circuit which satisfies the requirements of the safety category.
• Do not place a PLC in the circuit between the interlock switch
and the load. Safety security can be endangered in the event
of a malfunction of the PLC.
• Do not disassemble or modify the interlock switch, otherwise a
malfunction or an accident may occur.
• Do not install the actuator in the location where a human body
may come in contact. Otherwise injury may occur.
• Regardless of door types, do not use the interlock switch as a
door stop. Install a mechanical door stop at the end of the door
to protect the interlock switch against excessive force.
• Do not apply excessive shock to the interlock switch when
opening or closing the door. A shock to the interlock switch
exceeding 1,000 m/s
2
may cause damage to the interlock
switch.
• If the operating atmosphere is contaminated, use a protective
cover to prevent the entry of foreign objects into the interlock
switch through the actuator entry slots.
• Entry of a considerable amount of foreign objects into the
interlock switch may affect the mechanism of the interlock
switch and cause a malfunction.
• Do not store the interlock switches in a dusty, humid, or
organic-gas atmosphere.
• Use proprietary actuators only. When other actuators are
used, the interlock switch may be damaged.
• Cover the unused actuator entry slot using the slot plug
supplied with the interlock switch.
Mounting
Mount the interlock switch on the
machine. Mount the actuator on the
hinged door.
Note: When mounting an actuator, make sure
that the actuator enters into the slot in
the correct direction, as shown on the
right.
Recommended Screw Tightening Torque
• Interlock switch (M4 screw): 1.0 to 1.5 N·m
• Actuator (M4 screw): 1.0 to 1.5 N·m
• Mounting bolts are not supplied, and must be purchased
separately by the user.
Note: The above recommended tightening torque of the mounting
screw is the value with hex socket head bolts. When other
screws are used and tightened to a smaller torque, make
sure that the screws do not become loose after mounting.
Cable
• Do not fasten or loosen the gland at the bottom of the interlock
switch.
• When bending cable during wiring, make sure that the cable
radius is kept at 40 mm minimum.
• When wiring, make sure that water or
oil does not enter from the end of
cable.
Wire Identification
• Wires can be identified by color and/or a white line printed on
the wire.
Terminal Number Identification
• When wiring, the terminal number on each contact can be
identified by wire color.
• The following diagrams show a safety (main) contact and one
or two auxiliary contacts for two-contact and three-contact
types.
• When wiring, cut any dummy insulation (black) and any
unused wires at the end of the jacket to avoid incorrect wiring.
