C. Connect a 24 VDC power supply to the DTA
terminals; positive to positive and negative to
negative. Close the Breaker manually. Energize
the DTA to trip the Breaker; de-energize when
the Breaker trips. Make certain that the DTA
resets. If the Breaker fails to properly trip or
reset, it may be necessary to readjust the cage
height. Make the necessary adjustments until
the trips and resets are sure and positive each
time.
For Kits Supplied with a Breaker Mounted
CPT Only.
Step 10:Installing the Breaker Mounted CPT
A. Secure the CPT to the CPT Mounting Bracket,
as shown, using the (4) .190-32 × .500" screws,
(8) flat washers, (4) lock washers, and (4) nuts
supplied. Note that the screws, with flat washers
installed, must be installed from the bottom of
the CPT Mounting Bracket, and the flat
washers, lock washers, and nuts are installed
from the top.
Note: The CPT Harness terminals (X1 and
X2) should be oriented to the side of the
CPT Mounting Bracket with two extra holes.
B. The CPT Harness will connect the CPT to the
Trip Unit. Temporarily position the plug-in
connection of the CPT Harness near the Top
Center of the Breaker. Route the Harness down
through the Breaker to the bottom left corner
making sure the Harness is clear of all moving
parts within the Breaker. Cut the Harness to a
suitable length for attachment to the CPT.
C. With the CPT Assembly setting in front of the
Breaker, strip .250" of insulation and attach a
.138" ring terminal to each wire of the CPT
Harness. Connect the wires to the X1 and X2
terminals of the CPT.
