SAFETY DANGER!
Electric shock hazard. Can cause injury or death. All wiring should be performed by a qualified electrician. Before attempting to perform any service or maintenance, turn the electrical power to unit to OFF at disconnect switch(es). Unit may have multiple power supplies.
SAFETY CAUTION!
Verify power before wiring the supply and
control voltage. Greenheck is not
responsible for any damage to, or failure of the unit caused by incorrect field wiring.

Installation

Electrical Connections

The electrical supply must be compatible with that shown on the nameplate: voltage, phase, and amperage capacity. Connect power to the unit per the unit specific wiring diagram located on the inside of the control center access door. The wiring diagram indicates which electrical accessories were provided on the unit. The electrical supply line must be properly fused and conform to local and national electrical codes.

All internal electrical components are pre-wired at the factory. To determine what specific electrical accessories were provided with the unit, refer to the unit specific wiring diagram located in the unit control center. Field electrical connections required:

1) supply power to the main disconnect (See FIGURE 7, Item #1). A door interlocking safety disconnect is provided as a standard feature.

2)low voltage control power to the 24 VAC control circuit (See FIGURE 7, Item #7).

IMPORTANT: Use minimum 14 ga. wire for 24 volt control power. Control wire resistance should not exceed 0.75 ohms (approximately 285 feet total length for 14 ga. wire; 455 feet total length for 12 ga. wire). If wire resistance exceeds 0.75 ohms, an industrial-style, plug-in relay should be added to the unit control center and wired in place of the remote switch (typically between terminal blocks R and G on the control strip — See FIGURE 7, Item #7). The relay must be rated for at least 5 amps and have a 24 VAC coil. Failure to comply with these guidelines may cause motor starters to “chatter” or not pull in which can cause contactor failures and/or motor failures.

Control wires should not be run inside the same conduit as that carrying the supply power. The unit must be electrically grounded in accordance with the current National Electrical Code, ANSI/NFPA-70.

Note: Standard factory installed electric pre-heaters and post-heaters have their own disconnect separate from the unit disconnect. Thus, each electric heater requires its own separate power connection.
