GK Solenoid Safety Interlock Switch
Step 3 - Wire switch:
IMPROPER INSTALLATION
Strictly adhere to all electrical connection
instructions.
Failure to comply with these instructions
could result in death or serious injury.
• Refer to Figures 5, 6, 7, and 8 for 1NC - 1NO
wiring configuration.
• M3 spade terminals up to 6,35 mm (0.25 in) wide
may be used with contact block should additional
wiring be required.
• Solenoid is prewired to the terminal strip.
• Torque wire connections as follows:
− Torque connector to secure cable to switch
enclosure (if required): 1,8-2,2 N-m
(16-10 in-lb).
− Torque switch terminal screws: 0,8-1,0 N-m
(7-9 in-lb) M3.
− Torque ground screw: 0,8-1,0 N-m (7-9 in-lb)
M3.
Step 4 - Seal conduit entry:
• Seal with Teflon tape or pipe sealant.
• If connector is used to secure cable to switch
enclosure, torque connector to 1,8-2,2 N-m
19 in-lb).
• Plug any unused conduit entry (plug included).
Seal with Teflon tape or pipe sealant.
PERFORM MECHANICAL FUNCTION TEST
• Open and close protective guard several times to
ensure key slides easily into switch head.
PERFORM ELECTRICAL FUNCTION TEST
• Close the protective guard and ensure switch
locks. It must not be possible to open the
protective guard when hazardous motion is
present.
• After the switch unlocks, open the protective
guard. The hazardous motion must not start
when the protective guard is unlocked or open.

• If wear, damage, or contamination is found,
replace the entire switch and key assembly. Do
not replace individual parts.
• Do not exceed one million switching operations.
Failure to comply with these instructions
could result in death or serious injury.
Maintenance frequency will be determined by the
type of machinery, the frequency of operation, the
application, and the local environment. Inspect for
and correct the following:
ROUTINE MAINTENANCE CHECKLIST
√
Switch and key mounting. Mounting should
be secure and permanent.

Wear or mechanical damage.
√
Correct electrical and mechanical switching
function.
√
Switch sealing. Ensure there are no liquids
in switch enclosure.
