Electrical Wiring - Airxcel 47000 Série Instructions D'installation

ROUTING 115 VAC WIRING
Following Airxcel, Inc. high voltage wiring specifications and
all local and national electrical codes, route the roof top unit
115 VAC supply wiring from its power source to the wirebox.
High Voltage Wiring Specifications based on Minimum
Overcurrent Protection Device Amperage – (see upper unit
nameplate)
1. U.L. requires copper conductors only with minimum
#12 AWG when using the minimum recommended
overcurrent protection device. Higher rated devices or
longer wiring runs will require #10 AWG or greater
copper conductors.
2. To prevent voltage drops greater than 10% during
starting loads, adhere to the following guideline:
For lengths greater than 50', use #10 AWG or larger
copper conductors. Match to the overcurrent protection
device provided.
Circuit Protection – Refer to upper unit nameplate.
High Voltage Wiring Specifications based on Overcurrent
Protection Device rated higher than the minimum required
(see upper unit nameplate)
Follow all local and NEC (National Electrical Code) for proper
sizing of wire AWG based on Overcurrent Protection Device
selected and the length of the wiring run to the air conditioner.
DANGER – SHOCK HAZARD
MAKE SURE THAT ALL POWER SUPPLY TO THE
UNIT IS DISCONNECTED BEFORE PERFORMING
ANY WORK ON THE UNIT TO AVOID THE
POSSIBILITY OF SHOCK INJURY OR DAMAGE TO
THE EQUIPMENT.
WHEN USING NON-METALLIC
SHEATH CABLES (ROMEX, ETC.),
STRIP SHEATH BACK TO EXPOSE
4-6 INCHES OF THE SUPPLY LEADS.
STRIP THE INDIVIDUAL WIRE LEAD
ENDS FOR WIRE CONNECTION
VI. ELECTRICAL WIRING
DANGER
(ABOUT 3/4" BARE WIRE). INSERT
THE SUPPLY WIRES INTO THE
ELECTRICAL CONNECTOR CLAMP.
SHEATH MUST PROTRUDE PAST
THE CLAMP BUSHING INSIDE THE
BOX AS ILLUSTRATED. MAKE SURE
SHEATH CABLE IS CENTERED IN
CLAMP BEFORE TIGHTENING UP
ON IT. DO NOT OVERTIGHTEN!!
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).
TO PREVENT THE POSSIBILITY OF
SHOCK INJURY, 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.
