Important: It is the responsibility of the machine builder (user) to make sure the wiring/cabling is not easily
manipulated by an operator to defeat the safety function(s); for example, cannot remove a switch from the
system.

Each actuator style has its own minimum door radius to ensure that its tongue smoothly enters the opening of the head of
the switch.
• SI-QM-SSA-2: 800 mm
• SI-QM-SSA-2RA: 600 mm
• SI-QM-SMFA-3: 400 mm
• SI-QM-SMFA-2: 150 mm
2.3.1 Position the Actuator Head
The actuator head can be rotated in increments of 90° to create eight possible actuator positions (four horizontal and four
vertical positions). Follow these steps to rotate the head.
The actuator can enter the actuator head either horizontally (at a right angle to the switch length) or vertically (in-line with the
switch length). If vertical actuation is required, move the small cover from the opening in the top of the head to the opening
in the side of the head. To rotate the head:
1. Loosen the four screws (TX10) on top of the actuator head.
2. Set the actuator head to the desired direction.
3. Tighten the four screws to 1.6 N·m.
4. Verify the unused actuator slot is closed with the sealing cap.
2.3.2 Install the Switch and Actuator
Follow these steps to mount the switch and actuator.
CAUTION: When ambient temperatures are above 40 °C, the housing temperature may be hot enough to
cause a dangerous situation. Do not allow the housing to come into contact with people or with
flammable material.
1. Verify the mounting surface is flat.
2. Mount the safety switch, tightening the four M5 (#10) screws to 2 N·m.
3. Insert the actuator, in the correct position, into the head of the switch until the actuator molding rests against the
head's housing.
