2.5.4 Electrical Connections - Condensing Unit<br />
Refer to 2.4.4 - Electrical Connections, Evaporator or Chilled-Water Unit and Figure 14 for<br />
general wiring requirements and cautions. Refer to electrical schematic when making connections.<br />
Refer to unit serial tag for full load amp and wire size amp ratings.<br />
<strong>Power</strong> Connections<br />
The condensing unit requires its own power source and earth ground, with a disconnect switch to isolate<br />
the unit for maintenance.<br />

Condenser Coil<br />
Field-supplied control wires must be connected between the evaporator and the condensing unit (See<br />
Figure 14 and the electrical schematic on the units for more details.) Seven (7) wires are required<br />
between the evaporator and condensing unit. Eighth and ninth wires are required on systems with<br />
hot gas bypass.<br />
