Step 5: Installing the Aux. CT Module
A. Secure the Aux. CT Module and the Aux.
CT Module Mounting Brackets to the Glass
Poly Barrier, as shown, using the (6) spacers,
(4) .190-32 × 1.00" screws, (4) flat washers, (4)
lock washers, and (4) nuts supplied. Note that
three (3) spacers are used under each end of
the Aux. CT Module.
B. Mount the Aux. CT Module Assembly on the
top of the Breaker Back Plate using the holes
drilled in Step 3a and the (2) .250-20 × .750"
screws, (4) flat washers, (2) lock washers, and
(2) nuts supplied.
C. Remove the Glass Poly Barrier covering the
7-Point Terminal Block on the Aux. CT Module.
D. Connect the Sensor Harness to the proper
terminals on the Aux. CT Module. Refer to
Section 12 of the Retrofit Application Data,
supplied with the Retrofit Kit, for detailed wiring
specifications.
Connect the green ground wire from the
Sensor Harness (with the ring terminal) to the
left side of the Aux. CT Module, as shown, using
the (1) .190-32 × .375" screw supplied.
E. Connect the “+” wire of the DTA Extension
Harness to the “OP” terminal of the Aux. CT
Module and the unmarked wire to the “ON”
terminal. Route the DTA Extension under to
Aux. CT module, towards the right side of the
Breaker, then down between the right Breaker
Frame and the Insulation Plate. Final routing
and connection of the DTA Extension Harness
will be performed later in the Retrofit process.
F. Reinstall the Glass Poly Barrier, removed in
