Digitrip Retrofit System for the ITE
LG-3000 (Frameless) Circuit Breaker
B. Align the two (2) large holes in the CPT
Mounting Bracket with the bolts used to secure
the Control Panel Mounting Bracket to the
Breaker. Using the original washers and nuts,
secure the CPT Mounting Bracket to the
Breaker as shown.
C. Secure the CPT to the CPT Mounting Bracket,
as shown, using the (4) .190-32 x .500" screws,
(8) flat washers, (4) lock washers, and (4) nuts
supplied.
Note:
The CPT Harness terminals (X1
and X2) should be oriented towards the
bolts securing the CPT Mounting Bracket
to the Breaker.
D. 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 right corner
to the CPT, 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.
E. 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.
F. Attach the HV Wires to the CPT terminals to
achieve the required voltage. (See the
following table.)
Standard CPT (Style #9A10037G01 & G02)
Voltage Required
CPT Terminals Used
480 Volt Circuit
H1 & H4
240 Volt Circuit
H2 & H4
208 Volt Circuit
H3 & H4
Special Order 575 Volt CPT
(Style #9A10037G03 & G04
)
Voltage Required
CPT Terminals Used
575 Volt Circuit
H1 & H4
460 Volt Circuit
H2 & H4
230 Volt Circuit
H3 & H4
Note:
The terminals to which the HV wires are
connected determine the voltage of the CPT
which, in turn, limits the voltage of the Breaker.
Verify that the line voltage of the circuit matches
the CPT voltage BEFORE putting the Breaker
into service.
