Wire Connection
• Make an opening for wire connection by breaking one of the con-
duit-port knockouts on the switch housing using a screwdriver.
• Before breaking the knockout, temporarily remove the connector-fix-
ing lock nut from the switch.
• When breaking the knockout, take care not to damage the contact
block or other parts inside the switch.
• Cracks or burrs on the conduit entry may deteriorate the housing
protection.
• When changing to the other conduit port, close the unused opening
with an optional plug (accessory).
Manual Unlocking
• Remove the screw located on the unlocking entry at the side of the
switch using the key wrench included with the switch. Then insert a
small screwdriver into the switch to push the lever inside of the
switch toward the indicator until the actuator is unlocked (refer to
the diagram on the right).
• Insert a small screwdriver into the elliptical hole on the back of the
switch, then push the lever inside of the switch toward the indicator
until the key is unlocked (refer to the diagram on the right).
1. This unlocking method is intended for an escape from a
machine when a person is locked in. For access to the
unlocking entry, an access hole should be opened on the
mounting panel. When opening the hole, apply proper pro-
tection against water or other foreign objects.
2. Caution: After the unlocking operation, put the screw
back into the unlocking entry for safety.
• Regardless of door type, do not use the safety switch as a locking
device. Install a locking device independently, for example, using a
metal latch (also applicable to Type HS1E).
• The safety switch cover can be only removed with the special key
wrench supplied with the switch or with the optional screwdriver
(applicable to HS1B and HS1E).
• Remove the screw located on the unlocking entry at the side of the
switch using the key wrench included with the switch. Then insert a
small screwdriver into the switch to push the lever inside of the
switch toward the indicator until the actuator is unlocked (refer to
the diagram on the right).
Caution: After the unlocking operation, put the screw back
into the unlocking entry for safety.
