Before connecting power to the module, read and understand
the entire section of this document. As-built wiring diagrams
are furnished with each module by the factory, and are
attached either to the door of the unit or provided with a
paperwork packet.
Electrical wiring and connections should be done in
accordance with local ordnances and the National Electric
Code, ANSI/NFPA70. Be sure the voltage and phase of the
power supply and the wire amperage capacity is in accordance
with the unit nameplate. For additional safety
information refer to AMCA publication 410-96, Recommended
Safety Practices for Users and Installers of Industrial and
Commercial Fans.
1. Always disconnect power before working on or near
this equipment. Lock and tag the disconnect switch or
breaker to prevent accidental power up.
2. Make certain that the power source is compatible with
the requirements of your equipment. The Air handler
wiring schematic and the compressor documentation
identifies the proper phase and voltage of the
equipment.
3. Secure the power cable to prevent contact with sharp
objects.
4. Do not kink power cable and never allow the cable to
come in contact with oil, water, grease, hot surfaces or
chemicals.
5. There are RC, Y1, and Y2 terminals for cooling in the
electrical control package or heated make up air. These terminals must be connected to the
matching terminals in the condenser.
6. Before powering up the DX module and compressing unit, make sure that the interior of the unit is
free of loose debris or shipping materials, and all refrigerant piping is complete.
WARNING!!
Disconnect power before
installing or servicing module.
High voltage electrical input is
needed for this equipment. This
work should be performed by a
qualified electrician.
