4. Mount the flameproof packing adapter body to conduit connection (Figure 36) by:
a. Screwing the flameproof packing adapter into the terminal box until the O-ring
touches the wiring port (at least 6 full turns), and firmly tightening the lock nut.
b. Inserting the cable through the union cover, the union coupling, the clamp nut, the
clamp ring, the gland, the washer, the rubber packing, and the packing box, in that
order.
c. Inserting the end of the cable into the terminal box.
d. Tightening the union cover to grip the cable. When tightening the union cover,
tighten approximately one turn past the point where the cable no longer moves up
and down.
CAUTION
Proper tightening is important. If it is too tight, a circuit break
in the cable can occur; if not tight enough, the flameproof
effectiveness is compromised.
e. Fastening the cable by tightening the clamp nut.
f. Tightening the lock nut on the union cover.
g. Connecting the cable wires to each terminal.
