When installing on a ferromagnet
In order to avoid electric shock or fire, turn power off before instal-
lation, 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-ZC1 . 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 switch .
Do not store the non-contact interlock switches in a dusty, humid,
organic-gas atmosphere, or areas subject to direct sunlight .

Do not install the actuator in the location where the human body
may come in contact . Otherwise injury may occur .
Tensile force on the cable may cause disconnection . Be sure
to secure the cable near the non-contact interlock switches .
Do not use the non-contact
interlock switch as a mechanical
stop for movable guard.
Do not use a hammer to adjust
a position of the non-contact
interlock switch.
Do not use the non-contact interlock switch in a magnetic
field of 0.3 mT or over.
