B. Reinstall the 7-Point Terminal Block Cover
removed in Step 8-I.
C. Route the Sensor Harness through the existing
hole near the bottom right corner of the
Molded Breaker Back Plate.
D. For Kits Supplied with a PT Module Only:
Refer to Section 7-3, Power Flow Convention
of the Retrofit Application Data, supplied with
the Retrofit Kit for additional wiring information
and to verify the Phase Convention used on
this Breaker Application.
NOTE: Before cutting the PT Wires, verify the
Phase Convention used on the Breaker
Application.
Route the PT Wires to a position suitable for
attachment to the bottom Stationary Contact
Assemblies. Move the PT Wire markers to a
position where they will still be attached to the
wires after cutting. Cut the wires to length,
strip an appropriate length of insulation from
each wire, and install a .375" ring terminal on
each wire.
Connect the wires to the bottom Stationary
Contact Assemblies using the (3)
.375-16 × 2.25" bolts left loose in Step 3-B.
For Kits Supplied with a Breaker Mounted CPT
Only.
NOTE: The High Voltage (HV) Wires have a LOAD
Side and a LINE Side. The HV Wires must
be installed in the correct orientation
during the following procedure. For the
purpose of identification, the words “Load
Side” are marked on the female fuse
receptacle of each HV Wire.
Fig. 31 Connection of the PT Wires and Routing
of the Sensor Harness
NOTE: The Load Side HV Wires are longer than
necessary and are cut during the following
steps. Before cutting the wires, be sure
that sufficient length is left so that the
connections can be made to the correct
terminals on the CPT.
E. Temporarily place the HV Fuses near the top of
the Trip Unit. Route the Load Side HV Wires to
the “H” terminals on the CPT. Mark and cut
the Load Side of each HV Wire to an appropri-
ate length for connection to the CPT. Strip an
appropriate length of insulation from the Load
Side HV Wires and attach a .138" ring terminal
to each. Attach the HV Wires to the CPT
terminals to achieve the required voltage
(see Table 2).
