PERSONAL INJURY
DO NOT use these products as safety or emergency stop
devices or in any other application where failure of the
product could result in personal injury.
Failure to comply with these instructions could result in
death or serious injury.
mWARNING
IMPROPER INSTALLATION
Consult with local safety agencies and their
requirements when designing a machine control link,
interface, and all control elements that affect safety.
• Strictly adhere to all installation instructions.
Failure to comply with these instructions could result in
death or serious injury.
3b. Care should be taken to ensure that all mounted
hardware cannot become detached during the
operational lifetime in the intended application
4.
Loosen the screws on the switch’s cover and remove it.
5.
For switches where the cable gland is not provided, use a
gland rated Type 1 or higher to maintain the integrity of the
enclosure-type rating.
6.
Loosen gland cover, then torque the gland to the switch’s
cover using 1 Nm to 2 Nm [8.85 in-lb to 17.7 in-lb] of force.
Ensure the o-ring was assembled between the gland and
the switch cover.
7.
Use copper conductors rated at 75°C or higher. Thread the
cable through the gland cover and gland, then press the
wire into the contact block’s terminals.
8.
Refer to circuit diagram on switch’s cover. Insert the
terminals into the switch and then fully fix terminal screws:
0,5 Nm to 0,6 Nm [4.42 in-lb to 5.31 in-lb].
9.
Perform functional tests. After wiring, use a voltmeter to
ensure when the switch is operated (turned off and on) that
a change of state occurs.

Disassemble the head’s cross-type (combo-head) screw.
Do not loosen or remove the other two Torx® screws.
Remove the switch cover by loosening the three (3) cover
screws.
Lift slightly on the switch head.
Rotate the switch head to the desired direction ensuring
the clip is still engaged with the head-neck slot.
If clip dislodges, return the clip to its location above the
contact blow and below the top of the switch housing by
fully re-inserting the clip.
Re-insert the cross-type (combo head) screw to reassemble the switch’s head, 0,4 Nm to 0,5 Nm [3.54 in-lb
