2.
Securely fasten enclosure to the mounting location, then attach
into conduit system.
3.
If remote indicating systems are used, be sure they comply with
NEC requirements, ensure grounding continuity, and are within
electrical ratings listed on the Field Wiring Diagram.
Hammers or prying tools must not be allowed to damage the
flat ground-joint surfaces or cover gasket.
Clean both ground-joint surfaces of body and cover before
closing. Dirt or foreign material must not accumulate on flat
ground-joint surfaces. Surfaces must seat fully against each
other to provide a proper explosionproof seal.
4.
Open cover for access to terminal block. Attach field wiring to
terminal block and to additional green ground lug, following the
wiring pattern established for your system and the Field Wiring
information contained in this instruction sheet.
5.
Check wiring for correctness with continuity tester and for
unwanted grounds with insulation resistance tester.
6.
Close cover and tighten all cover bolts, torque to 15-20 ft. lbs.
(20.3-27.1 Nm).
Make sure wire casing is safely tucked into enclosure before
closing EGL cover.
CAUTION:
AVOID DAMAGE WHILE CLOSING COVER.

•
Before assembling any mating threads, make certain that
there is no dirt or other foreign material on, or in, either set
of threads.
•
Conduit(s), and any plug(s) threads must be engaged
properly with their mating threads and securely tightened.
•
All threaded joints in the enclosure have been treated at the
factory with Crouse-Hinds STL screw thread lubricant which
acts as a lubricant and anti-seize agent. Whenever any
threaded joint(s) are disassembled, the threads should be
re-treated with STL and care must be exercised in mating
threads properly, and securely tightening the threaded
joints.
NOTES:
1.
For standard 120V supply voltage, connect leads directly to
terminals: "1" for power, "2" for neutral, "3" for ground. The
additional ground wire must be attached to the green wire lug,
which is factory installed in the enclosure. For 240 or 480 volt
control voltages connect leads directly to the transformer as
marked.
2.
Terminals 4, 5, 6, 7, 8, and 9 on the terminal block are
connected to the control relay's contacts and are to be used for
connections to remote indicators or control circuits. The
electrical ratings for the relay's contacts are given on the field
wiring diagram. Terminals 4 & 5 and 7 & 8 are normally open.
Terminals 4 & 6 and 7 & 9 are normally closed.
