1.Electrical data is for each individual motor.

2.Max Overcurrent Protection device permitted by N.E.C. 440-22 (1993) is 225% of the largest compressor motor RLA plus the remaining motor RLA and FLA values.

3.Minimum circuit ampacity is 125% of the largest compressor motor RLA plus the remaining motor RLA and FLA values.

4.Recommended dual element fuse size is 150% of the largest compressor motor RLA plus the remaining motor RLA and FLA values.

5.Kw values are taken at conditions of 45ºF saturated suction temperature at the compressor and 95ºF ambient.

6.Local codes may take precedence.

Field Installed Control Wiring

WARNING

Hazardous Voltage!

Disconnect all electric power, including remote disconnects before servicing. Follow proper lockout/tagout procedures to ensure the power can not be inadvertently energized. Failure to disconnect power before servicing could result in death or serious injury.

Before installing any connecting wiring, refer to Figure 3 to Figure 8 for the electrical access locations provided on the unit. Install appropriately sized control wiring for the 115 volt electrical components as required by the application.

Since the unit-mounted 115V control power transformer (1T1) is provided on all units, it is not necessary to run a separate 115 volt control power source to the unit.

Note: 200/230 Volt units are shipped with transformer 1T1 wired for 200 volt operation. If the unit is to be operated on a 230 volt power supply, rewire the transformer as shown on the unit schematic.

Controls Using 115 VAC

WARNING

Hazardous Voltage!

Disconnect all electric power, including remote disconnects before servicing. Follow proper lockout/tagout procedures to ensure the power can not be inadvertently energized. Failure to disconnect power before servicing could result in death or serious injury.

Install appropriately sized 115 volt control wiring for the electrical components as required by the application.

These components may include: hot gas bypass solenoid wiring; supply fan interlock and control circuit;

system control switch wiring (“No Control” units); step controller wiring (“No Control” units); chilled water pump interlock wiring (EVP units); chilled water flow switch wiring (EVP units); outside air thermostat wiring (EVP units):
