Make sure that the D4BS is located outside the safety door and that
no metal dust, oil, or chemical will be sprayed onto the D4BS. Other-
wise, the D4BS may soon fail to operate due to the penetration of
metal dust, oil, or chemical.
Tightening Torque
Be sure to tighten each screw of the D4BS properly, otherwise the
D4BS may malfunction.
Note: 1.
Apply a torque of 0.78 o 0.88 N·m if the D4BS is a three-con-
duit model.
2.
Apply a torque of 4.90 to 5.88 N·m in the case of an Allen-
head bolt. If it is a pan head screw, apply a torque of 2.35 to
2.75 N·m.
Mounting Dimensions (M5)
The D4BS can be mounted more securely by adding two protruding
portions, each of which is 5 mm maximum in height and
