Wiring
WARNING: WIRING SHOULD BE PERFORMED ONLY BY QUALIFIED
PERSONS.
WARNING: BEFORE WIRING THE AUTOTRANSFORMER, ENSURE THAT
ALL SOURCES OF POWER ARE DISCONNECTED. NEVER WORK ON A
LIVE CIRCUIT.
CAUTION: THE CONFIGURATION OF THE AUTOTRANSFORMER IS FOR
STEP-UP, STEP-DOWN OR CURRENT BALANCING. IT DOES NOT
PROVIDE ISOLATION BETWEEN INPUT AND OUTPUT. DO NOT USE THE
AUTOTRANSFORMER AS AN ISOLATION DEVICE.
NOTE: All source connections (inverter, generator or utility) are connected to
the left-hand side of the installed circuit breaker (see illustrations). All loads
connect to the service crimp on the right-hand side of the breaker.
Service Crimps
The service crimps provide a convenient means to connect the
autotransformer. Do not use the screw terminals on the breakers for making
connections. Do not remove factory wiring.
Pull back the insulation on the TRANSFORMER wire so it is exposed
inside the service crimp.
Strip off approximately 1/2 inch of the insulation from the wire to be
installed and insert the bare wire into the crimp.
Slide the crimp up to the circuit breaker terminal as far as it will go.
Place the wire in the crimp and ensure the existing wires insulation is fully
exposed. Torque the crimp screw to 45 inch/pounds.
After torquing, ensure the service crimp is tight on both wires and is not
able to twist or be moved.
CAUTION: UNUSED SERVICE CRIMPS SHOULD BE TIGHTENED TO THE
EXISTING WIRE AND TAPED, SO IT CAN NOT SHORT TO OTHER
TERMINALS OR THE CASE.
