Issue:
Wiring diagram for the outdoor receiver heaters.
Product line:
Condensers
Environment:
Data Center Cooling
Cause:
 
Resolution:

The heater per the unit submittal package is field wired.  A junction box is typically placed at the receiver and the heater whip is pulled into this box where a small terminal bock is placed.  From the junction box a conduit whip can be connected to carry the wire to its final termination.  If the unit is 208/230 the incoming power can be split and the heater can be wired direct with fuses to protect the condenser if the heater should ever short out.  If the condenser voltage is 460/480v, a transformer is required (field supplied) this can be mounted externally under the control box and wired accordingly.
