SWITCH MOUNTING, WIRING AND SEALING
In order to comply with EN418, install a cable pull
switch at each end of the cable.
Step 1 - Ensure you have the following:
• Switch.
• (2) #10-32 UNF screws.
• #14-#16 AWG stranded or #16-#18 AWG solid
wire.
Step 2 - Mount switch:
SWITCH DAMAGE
Do NOT mount switch upside down or at low point
of conduit runs. Condensation problems may
develop.
Failure to comply with these instructions may
result in product damage.
• Single head: Mount using two #10-32 UNF
screws from either front or back of switch. Ensure
a minimum of four threads of engagement.
Torque to 43-52 in-lb (4,-5,9 N-m).
• Duplex head: Mount using two #10-32 UNF
screws through mounting feet on left and right of
switch enclosure. Ensure a minimum of four
threads of engagement. Torque to 43-52 in-lb
(4,9-5,9 N-m).
