BOX. MAKE SURE SHEATH CABLE IS
CENTERED IN CLAMP BEFORE
TIGHTENING IT. DO NOT OVER-
TIGHTEN!! THIS COULD RESULT IN
PINCHING THROUGH THE PLASTIC
WIRE INSULATION AND CAUSE
SHORTING OR "HOT" WIRES TO
GROUND (SHOCK HAZARD). THE
CLAMP IS INTENDED FOR STRAIN
RELIEF OF THE WIRES, SLIGHT
PRESSURE IS USUALLY SUFFICIENT
TO ACCOMPLISH THIS.
IF OTHER THAN NON-METALLIC
CABLES ARE USED FOR SUPPLY
CONDUCTORS, APPROPRIATE
STRAIN RELIEF CONNECTORS OR
CLAMPS SHOULD BE USED.
IN NO CASE SHOULD CLAMPING
OR PINCHING ACTION BE APPLIED
TO THE INDIVIDUAL SUPPLY LEADS
(NEUTRAL AND "HOT" WIRES).
D) The installer must form a drip loop in the
high voltage wiring routed between the
"Rain Tight" electrical fitting and the high
voltage terminal board wiring lugs. Do not
allow excess wiring to contact electrical
terminals, sharp screw ends or edging that
can cut or damage the wiring insulation.
E) After connecting the ground wire to the
grounding lug, verify that the ground wire
(which in some instances will be bare
copper) cannot come into contact with any
high voltage terminal.
6. Circuit 1 and 2 Origination Points
When both cooling systems (stage 1 and 2) cannot be
powered from a single shore line, then the system
must be wired as follows:
1. Connect "CIRCUIT 1" to the circuit that is
powered from the vehicle shore line. This
allows stage 1 cooling to operate anytime
the shore line is connected to either the
local utility or the on-board generator.
2. Connect "CIRCUIT 2" to the circuit that is
powered from the on-board generator.
When wired in this fashion, stage 2 cooling
will operate only when the on-board
generator is in operation.
3.
TO PREVENT THE POSSIBILITY
OF SHOCK INJURY FROM
APPLIANCE OPERATION:
THE WHITE WIRE MUST BE
CONNECTED TO NEUTRAL IN
THE SERVICE BOX ENTRANCE
AND THE MECHANICAL
GROUND MUST BE CONNECTED
TO A GROUNDING LUG EITHER
IN THE SERVICE BOX OR THE
MOTOR GENERATOR
COMPARTMENT.
