For proper wiring connections, consult the wiring diagram located
inside the compressor terminal box cover and Fig. 2 for wiring
connection locations. Refer to Fig. 2-4 for terminal plate
components.
Fig. 2 — Terminal Box Arrangement
Terminal Box
All UL recognized 06CC compressors have terminal enclosures
that are suitable for outdoor use equipment as a sole enclosure.
The compressor terminal box is supplied with a support plate to
mount the connector for the power wiring conduit. The support
plate can be fastened to the terminal box with the (4) screws pro-
vided.
Terminal Plate Wiring
The parts listed in Table 1 are supplied in a parts bag with the
compressor and are used when wiring the terminal plate. Refer to
Step 4 in the General section on page 1 and Table 1. Customer
supplied wiring to the compressor terminal plate must be provided
with insulated wire terminal connectors and be suitable for accom-
modating the 3/8 in. diameter terminal studs. Figure 3 shows the
wiring components of the terminal plate. Jam Nut No. 1 is factory-
installed and should not be disturbed. Jam Nut No. 2 should be in
contact with the underside of the jumper bar or ring terminal if no
jumper bars are used. Jam Nut No. 2 should be installed finger
tight, never torqued with a wrench. Jam Nut No. 3 should be in
contact with the upper side of the jumper bars or ring terminal and
should be wrench torqued.
