ELECTRICAL WIRING

WARNING

HIGH VOLTAGE!

DISCONNECT ALL POWER BEFORE SERVICING OR INSTALLING THIS UNIT. MULTIPLE POWER SOURCES MAY BE PRESENT. FAILURE TO DO SO MAY CAUSE PROPERTY DAMAGE, PERSONAL INJURY OR DEATH.

WARNING

HIGH VOLTAGE!

TO AVOID PERSONAL INJURY OR DEATH DUE TO

ELECTRICAL SHOCK, DO NOT TAMPER WITH FACTORY

WIRING. THE INTERNAL POWER AND CONTROL WIRING

OF THESE UNITS ARE FACTORY-INSTALLED AND HAVE

BEEN THOROUGHLY TESTED PRIOR TO SHIPMENT.

CONTACT YOUR LOCAL REPRESENTATIVE IF

ASSISTANCE IS REQUIRED.

CAUTION

TO PREVENT DAMAGE TO THE WIRING, PROTECT WIRING FROM SHARP EDGES. FOLLOW NATIONAL ELECTRICAL CODE AND ALL LOCAL CODES AND ORDINANCES. DO NOT ROUTE WIRES THROUGH REMOVABLE ACCESS PANELS.

CAUTION

CONDUIT AND FITTINGS MUST BE WEATHER-TIGHT TO PREVENT WATER ENTRY INTO THE BUILDING.

For unit protection, use a fuse or HACR circuit breaker that is in excess of the circuit ampacity, but less than or equal to the maximum overcurrent protection device. DO NOT EXCEED THE MAXIMUM OVERCURRENT DEVICE SIZE SHOWN ON UNIT DATA PLATE.

All line voltage connections must be made through weather- proof fittings. All exterior power supply and ground wiring must be in approved weatherproof conduit.

The main power supply wiring to the unit and low voltage wiring to accessory controls must be done in accordance with these instructions, the latest edition of the National Electrical Code (ANSI/NFPA 70), and all local codes and ordinances. All field wiring shall conform with the temperature limitations for Type T wire (63°F/35°C rise).

The unit is factory wired for the voltage shown on the unit’s data plate. Refer to model nomenclature in Appendix D for voltage requirement for your unit.

NOTE: If supply voltage is 208V, lead on primary of trans- former must be moved from the 230V to the 208V tap. Refer to wiring diagram on unit for details.

Main power wiring should be sized for the minimum wire ampacity shown on the unit’s data plate. Size wires in accor- dance with the ampacity tables in Article 310 of the National Electrical Code. If long wires are required, it may be neces- sary to increase the wire size to prevent excessive voltage drop. Wires should be sized for a maximum of 3% voltage drop.

CAUTION

TO AVOID PROPERTY DAMAGE OR PERSONAL INJURY DUE TO FIRE, USE ONLY COPPER CONDUCTORS.

CAUTION

LABEL ALL WIRES PRIOR TO DISCONNECTION WHEN SERVICING

CONTROLS. WIRING ERRORS CAN CAUSE IMPROPER AND

DANGEROUS OPERATION. VERIFY PROPER OPERATION AFTER

SERVICING.

NOTE: A weather-tight disconnect switch, properly sized for the unit total load, must be field installed. An external field supplied disconnect may be mounted on the exterior panel.

Ensure the data plate is not covered by the field-supplied disconnect switch.

•Some disconnect switches are not fused. Protect the power leads at the point of distribution in accordance with the unit’s data plate.

•The unit must be electrically grounded in accordance with local codes or, in the absence of local codes, with the latest edition of the National Electrical Code (ANSI-NFPA 70). A ground lug is provided for this purpose. Size grounding conductor in accordance with Table 250-95 of the National Electrical Code. Do not use the ground lug for connecting a neutral conductor.

•Remove plug in panel located at the condenser end of unit and route conduit to control box. Remove plug in control box and connect power wiring to the contactor closest to the entrance. If Single Point kit is used, refer to Installation Instructions supplied with kit.
