SWITCH MOUNTING, WIRING AND SEALING
Step 1 - Ensure you have the following:
•
Switch.
•
(2) 1/4-20 or (2) 5/15-18 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.
•
Mount using (2) 1/4-20 screws from front of
switch, or with (2) 5/15-18 screws from back of
switch. Torque to 43-52 in.-lb (4.9-5.9 N-m).
Step 3 - Wire switch:
•
With a bar or screwdriver in the cover wrenching
lugs, loosen and remove circular cover on front of
switch.
•
Connect stranded or solid wire to switch’s
pressure type connector terminals. (Refer to
circuit diagram on switch housing. Diagram
depicts switch contacts when cable is at proper
tension.) Torque terminal screws and ground
screw to 7-9 in.-lb (0,8-1 N-m).
•
Reassemble cover and tighten securely.
Step 4 - Seal conduit connection: Proper sealing
ensures explosion-proof integrity of the conduit
system.
•
Seal in accordance with National Electrical Code,
paragraphs 500-2 and 501-4.
IMPROPER SYSTEM PERFORMANCE
•
Ensure the attendant circuitry is such that only the
momentary interruption of the control circuit cable
pull contacts is required to open and hold open
the control circuit until such time as both the cable
pull switch and the attendant circuitry are
manually reset.
•
The user is SOLELY RESPONSIBLE for
determining the appropriate level of risk
warranting this type of circuitry.
•
Maintained Cable Pull Limit Switches must be
installed in a fashion that complies with all codes
and standards that are applicable to the particular
application of the device.
•
Failure to comply with these instructions could
result in death or serious injury.
ACTUATING CABLE INSTALLATION
Step 1 - Ensure you have the following (Figure
2):
•
Plastic coated aircraft cable 1/8 in. (3,18 mm) to
3/16 in. (4,76 mm) dia. Use a distinctive color,
such as red, to differentiate actuating cable from
other wires or cables in the area.
•
Thimbles, U-bolt clamps.
•
Cable supports (eyebolts).
