CAUTION
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 main power supply shall be three-phase, three wire. The
unit is factory wired for the voltage shown on the unit’s data
plate.
NOTE:
If supply voltage is 208V, all leads on primary of trans-
former TRANS1 must be moved from the 230V to the 208V
tap.
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.
