In order to avoid electric shock or fire, turn the power off before
installation, removal, wire connection, maintenance, or inspection
of the non-contact interlock switch .
Safety category 4 (EN954-1) can be achieved by combining the
HS7A non-contact interlock switch and HR1S safety relay module
(monitor the dual contacts using the safety relay module) .
When using non-contact interlock switches, combine with a
propri etary safety relay module and confirm that the conformable
safety category and the safety category (EN954-1) required to the
machinery have been achieved .
Be sure to use the HS7A non-contact interlock switch in combina-
tion with the proprietary actuator HS9Z-ZP1 . Do not use other
actuators .
Regardless of door types, do not use the non-contact interlock
switch as a door stop . Install a mechanical door stop on the edge
of the door to protect the interlock switch against excessive force .
A shock to the door exceeding 300 m/s
a failure to the non-contact interlock switches .
Do not store the switches in a dusty, humid, organic-gas atmo-
sphere, or areas subject to direct sunlight .
