CS 3-Phase Installation Manual

Testing After Installation
• Apply utility power, and observe that only the Diagnostic LED
flashes on the circuit board. If it does not flash, the board may
be defective.
• The Charge Test buttons on the PC board simulate connection
to a vehicle. Push and hold the two Charge Test buttons at the
same time. The contactor should close, and the large Green
CHARGING light should turn on.
• If a vehicle is available, connect the CS 3-Phase to the vehicle
and verify that the contactor closes and the Green CHARGING
light turns on.
INSTALLATION IS COMPLETE.
• Only four wires are needed to wire the CS 3-Phase (Line 1,
Line 2, Line 3, and Service Ground), as shown in
Figure 7
.
Wire the unit from the breaker panel using wire sized according
to local electrical codes. The circuit breaker should be rated to
the appropriate size for the current draw. Derating a three phase
breaker 20% for continuous duty allows for 80% of continuous
current. For example, derating an 80A three phase breaker 20%
for continuous duty allows 64A of continuous current.
• The three phases (Line 1, Line 2, & Line 3) are terminated on
the input side of the contactor itself, as shown in
Figure 7
. The
Service Ground is terminated on the Ground Terminal at the
bottom of the inner chassis.
• Be careful not to damage the PC Board when removing the
power-entry knockout, attaching the conduit, or when wiring
the service conductors to the contactor.
