Safety Precautions
•
Install the rear unlocking button in a place where only the
operator inside the hazardous area can use it . Do not
install the button in a place where an operator outside the
hazardous area can use it, otherwise the interlock switch
may 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 for
Mounting Screws
•
HS5E-K 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) (Note)
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) (Note)
HS9Z-A53:
4 .5 to 5 .5 N·m (two M6 screws) (Note)
HS9Z-A55:
1 .0 to 1 .5 N·m (two M4 screws) (Note)
Note: The above recommended tightening torques of the
mounting screws are the values confirmed 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 .
•
Mounting bolts must be provided by the users .
•
To avoid unauthorized or unintended removal of the in-
terlock switch and the actuator, it is recommended that
the interlock switch and actuator are installed in a secure
manner, for example using special screws or welding the
screws .
•
When installing the HS9Z-A51A and HS9Z-A52A actua-
tors, use the washer (supplied with the actuator) on the
hinged door, and mount tightly using two M4 screws .
