Enclosure disassembly
1. Remove the back cover by loosening the cover screws.
2. Remove the top cover by loosening its two screws. This makes feeding the cable through the top
cable entry gland easier.
Wiring
NOTE: Ensure that only type SOW cable is used for the pendant.
NOTE: Use copper conductors only for terminal wiring. The conductor wire sizing should be AWG18 – 16,
and the temperature rating should be 60°C (140°F).
Ensure that the cable entry gland opening is at least 1.5mm smaller than the cable diameter that will be
fed through it. This difference ensures that the gland will squeeze the cable and provide a seal. The
inside diameter of the cable entry gland is marked in millimeters at its top edge. For example, if the top
number is 11.5, it means that the inside diameter of the top is 11.5mm. To seal properly, the cable would
have to be 13mm diameter or more. If the cable diameter is larger, one or more of the rings may be cut off
of the top of the cable gland to get a proper match between the cable and gland opening. In all cases, the
gland opening should be smaller than the cable by 1.5mm or more.
For more information on cable armor types and dimensions, see Appendix A – Cable Armor.
Take care that the jacket of the cable that will go through the cable gland is smooth all around. If there are
ridges from where the strain relief cables were peeled back, they may prevent a good seal.
The pendant is normally supplied with conical auxiliary cable armor. It sits on top of the cable gland (like a
hat) when wiring is complete. This is an additional cover for the gland-cable connection that can provide
extra protection against water intrusion. It should be trimmed with scissors (in a single cut) to the proper
size. It can be as small as one half (1/2) of the cable diameter that will pass through it because it can be
easily stretched. It must be at least 1mm smaller than the cable diameter that will pass through it. Smaller
is better within the stated limits as a smaller opening will provide a better seal.
1. Remove or loosen the strain relief cable clamp inside the top of the enclosure.
2. Feed the cable through the auxiliary cable armor, the cable entry gland, and the enclosure until
the cable extends along the entire length of the enclosure.
3. Strip back the cable outer jacket to within one inch of the internal strain relief clamp. The jacket
must be intact inside the clamp.
4. Screw the top cover to the enclosure making sure that the key ring is facing the front of the
pendant.
5. Tighten the internal strain relief cable clamp onto the cable jacket.
6. Cut, strip, and terminate each cable conductor. Keep all pieces of the cable cut during wiring out
of the enclosure. Use a UL-listed or CSA-certified, round, crimped-on terminal when connecting
to terminals. Do not solder the terminal onto the wire or connect the bare wires directly to the
switch terminal screws.
7. Fasten each cable conductor to its respective terminal screw. The tightening torque used should
be 10 – 12 lb-in. Do not over-tighten.
8. Check the internal strain relief cable clamp’s function. Make sure that there is no tension on any
conductors inside the pendant.
9. Mark the opposite ends of the cable’s conductors to ensure proper wiring to the control system.
