Digitrip Retrofit System for the ITE
LG-3000 (Frameless) Circuit Breaker
G. Attach the appropriate label for the Breaker in a
clearly visible position. Four (4) labels are
included with the CPT, one (1) for 575 Volt, one
(1) for 480 Volt, one (1) for 240 Volt, and one
(1) for 208 Volt systems.
H. The HV Wires will be cut to length and
connected to the Breaker later in the Retrofit
Process. Temporarily route the HV Wires out
the front of the Breaker so they do not interfere
with the Retrofit Process.
Step 5:
Installing the Sensors
A. For Kits Supplied with a Breaker Mounted CPT
Only. Install the grommet in the hole to the left
of center of the Sensor Mounting Bracket.
B. Align the Sensors, as shown, with the Sensor
Mounting Bracket. Note that the Sensor
Terminals are positioned in the cut-outs in the
Mounting Bracket and the Sensor Labels face
outward.
