Installation Power Wiring

Field Installed Power Wiring Power wiring to the equipment must conform to National and Local Electric Codes (NEC) by a professional electri- cian.

WARNING

Live Electrical

Components!

During installation, testing, ser- vicing and troubleshooting of this product, it may be necessary to work with live electrical compo- nents. Have a qualified licensed electrician or other individual who has been properly trained in handling live electrical compo- nents perform these tasks. Failure to follow all electrical safety pre- cautions when exposed to live electrical components could re- sult in death or serious injury.

Verify that the power supply available is compatible with the unit’s name- plate. Use only copper conductors to connect the power supply to the unit.

CAUTION

Use Copper Conductors Only!

Unit terminals are not designed to accept other types of conduc- tors. Failure to use copper con- ductors may result in equipment damage.

Main Unit Power Wiring

A field supplied disconnect switch must be installed at or near the unit in accordance with the National Electric Code (NEC latest edition).

Location of the applicable electric ser- vice entrance for HIGH (line voltage) may be found on the unit submittal at the front of this manual (pages 7 through 9).

The high voltage connection is made at the 1TB1 terminal block for the 20- ton equipment, and at 1K1 for the 2- ton through 6-ton equipment. The ter- minal block or contactor is located in- side the unit control box. Refer to the customer connection diagram that is shipped with the unit for specific ter- mination points.

Provide proper grounding for the unit in accordance with the local and na- tional codes.

Control Power Transformer

The 24-volt control power transform- ers are to be used only with the acces- sories called out in this manual. Transformers rated greater than 50 VA are equipped with internal circuit breakers. If a circuit breaker trips, turn OFF all power to the unit before at- tempting to reset it.

WARNING

Hazardous Voltage!

Disconnect all electric power, in- cluding remote disconnects be- fore servicing. Follow proper lockout/tagout procedures to en- sure the power can not be inad- vertently energized. Failure to disconnect power before servic- ing could result in death or seri- ous injury.

The transformer is located in the control box.
