Interlock switch selection considerations
•
•
•
•
The switch must be a DPST type switch, with normally closed, and
positively guided contacts. (refer to EN 1088, EN292-1 section
3.22.4, and EN 292-2 section 3.5)
Mounting the interlock switches
The interlock switch must be mounted in such a way that prevents
the actuator key from being latched into the interlock switch
while the gate/guard is in the open position (i.e. bypassing the
interlocking system).
The actuator key should be mounted to the gate/guard using
tamper-resistant hardware/screws.
Refer to EN 1088 for information regarding selection and
mounting of interlock switches.
Suggested Interlock Switch (consists of 3 separate parts)
Euchner/GP1-538HA-M (interlock switch with 2 NC force-guided
contacts)
Euchner/059 440 (metal hinged latch actuator key)
Euchner/M20CGP (cable entry gland nut)

Guard-lock selection considerations
•
•
•
The switch must be a DPST type switch, with normally closed, and
positively guided contacts. (refer to EN 1088, EN292-1 section
3.22.5, and EN 292-2 section 3.5)
The guard-lock must operate in such a way that the actuator key is
locked when inserted into the guard-lock when no power is applied,
and the actuator key may only be removed when power is applied to
the device. (refer to EN 1088 section 4.2.2)
Mounting the Guard-locks
The guard-lock must be mounted in such a way that prevents the
actuator key from being latched into the guard-lock while the
gate/guard is in the open position (i.e. bypassing the
interlocking/guard-locking system).
