Mechanical Installation
Horizontal or Vertical Actuation
Before installation, orient the switch actuator head for either horizontal (at a right angle
to the switch length) or vertical (in-line with the switch length) actuation. The switch is
shipped with the actuator head in the horizontal position (Figure 1). If this is the desired
orientation, install the M3 x 15 mm tamper-proof (one-way) screw, which is found in a
plastic bag, stored in the wiring chamber (see page 6 for information on opening the
wiring chamber access door).
If vertical actuation is required, remove the head by pulling straight up and off (Figure 2).
Re-orient the actuator head, and slide it back on in the new position until it snaps into
place. Install the tamper-proof screw, as shown in Figure 3.
Rotating Actuator Head to Desired Position
The actuator head may be rotated in increments of 90° to create eight possible actuator
engagement positions (i.e., four horizontal plus four vertical positions). To rotate the
head, pull the holding clamp forward, rotate the head (in either direction) to the desired
position, and push the holding clamp back in to lock. The head may be rotated with the
actuator either engaged or removed (Figure 4).
Installing the Switch and Actuator
NOTE: All mounting hardware is supplied by the switch user. The fasteners must be of
sufficient strength to avoid incidental breakage. Use of permanent fasteners or
locking hardware is recommended to prevent loosening or displacement of the
actuator and switch body.
The mounting holes in the switch body accept M5 (#10) screws. There are four holes
on a mounting pattern of 30 x 124 mm (see dimension drawing of switch, page 10). See
page 11 for dimensions of the actuator mounting holes.
Position the switch, with its actuator fully engaged, at the mounting location and mark
the mounting holes. Fasten the switch body and the actuator in place. The rigid in-line
actuator includes floating sleeves in the mounting holes to allow some forgiveness for
switch-to-actuator alignment. If the rigid in-line actuator is used, take care to not over-
tighten the actuator fasteners so as to allow this movement. After the mounting hardware
is secure, check the actuator/switch engagement for misalignment and binding.
IMPORTANT: A safety switch must be installed in a manner which discourages
tampering or defeat. Mount each switch to prevent bypassing of the switching
function at the wiring chamber. A switch and its actuator must never be used as a
mechanical stop.
Manual Release for Spring Lock Models
Models with spring lock/solenoid unlock may be unlocked manually by rotating the unlock
mechanism, using an M3 Allen wrench (not supplied). First loosen the security screw
(see dimension drawing of switch, page 10), then turn the unlock mechanism in either
direction to the position.
IMPORTANT: After the switch is installed, check to be certain that the unlock
mechanism is in the
position, and that the security screw is tight and covered with
tamper-resistant lacquer (user-supplied).
