•
be locked even if the door is closed, and the main circuit
remains open.
Safety Precautions
Install the rear unlocking button in the place where only
•
the operator inside the hazardous area can use it. Do not
install the button in the place where an operator outside the
hazardous area can use it, otherwise the interlock switch can
be unlocked during usual machine operation, causing danger.
Operate the rear unlocking button by hand only. Do not
•
operate using a tool or with excessive force. Do not apply
force to the button from the direction other than the proper
direction, otherwise the button will be damaged.
Recommended Tightening Torque
HS5E interlock switch: 1.8 to 2.2 N·m (four M4 screws)
•
(Note)
Rear unlocking button: 0.5 to 0.7 N·m
•
Rear unlocking button kit: 4.8 to 5.2 N·m
•
(M5 screw)
Actuators
•
HS9Z-A51:
1.8 to 2.2 N·m (two M4 screws)
HS9Z-A52:
0.8 to 1.2 N·m (two M4 Phillips screws)
HS9Z-A51A/A52A: 1.0 to 1.5 N·m (two M4 screws)
HS9Z-A53:
4.5 to 5.5 N·m (two M6 screws)
HS9Z-A55:

Note: The above recommended tightening torque of the mounting screws
are the values 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.
To avoid unauthorized or unintended removal of the interlock
•
switch and the actuator, it is recommended that the interlock
switch and the actuator are installed in an unremovable
manner, for example using special screws or welding the
screws.
When installing the HS9Z-A51A and HS9Z-A52A actuators,
•
use the washer (supplied with the actuator) on the hinged
door, and mount tightly using two M4 screws.
