B) Each circuit high voltage wiring must be
routed through a separate opening in the
outer cabinet of the wiring box. These
openings are referred to as the "power wire
entries". See Figure 1. RV Products
provides these two openings, each opening
is a 7/8" diameter opening.
C) Each circuit wiring must be secured at the
"power wire entry" by a U.L. listed "Rain
Tight" or equivalent electrical conduit
fitting. The fitting must be supplied by the
installer or vehicle manufacturer.
DANGER
WHEN USING NON-METALLIC SHEATH
SUPPLY CABLES (ROMEX, ETC.), STRIP
SHEATH BACK TO EXPOSE 4-6 INCHES
OF THE SUPPLY LEADS. STRIP THE
INDIVIDUAL WIRE LEAD ENDS FOR
WIRE CONNECTION (ABOUT 3/4" BARE
WIRE). INSERT THE SUPPLY WIRES
INTO THE ELECTRICAL CONNECTOR
CLAMP. SHEATH MUST PROTRUDE
PAST CLAMP BUSHING INSIDE THE
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.
DANGER - SHOCK HAZARD
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.
10. THERMOSTAT AND 12 VDC WIRING
THERMOSTAT OPERATING AND WIRING
REQUIREMENTS
The 6536 heat pump is designed to be operated from an RV
Products electronic wall mounted thermostat. See
Component Match-Up Section for thermostat part number
and description. The thermostat is designed to operate 12
VDC controlled heating and air conditioning systems. The
thermostat must be operated from a 12 VDC power source.
The thermostat can control one stage heating (user selectable
between fuel burning appliances or heat pump) and two stages
of cooling.
Maximum thermostat output for any load (including the furnace
control wire) is one amp.
The thermostat is equipped with a replaceable fast-acting 2 amp
fuse located on the base of the thermostat. The fuse is
designed to open if the furnace is mis-wired or there is a short
