HIGH VOLTAGE FIELD WIRING DIAGRAM
Provide flexible conduit supports
whenever vibration transmission may
cause a noise problem within the
building structure.
See Figure 5G for high voltage wiring
connections. Insure all connections are
made tight.
Note: For branch circuit wiring (main power supply to unit disconnect), Wire size for the
length of run should be determined using the circuit ampacity found on the unit
nameplate and the N.E.C..
For more than 3 conductors in a raceway or cable, see the N.E.C. for de-rating the ampacity
of each conductor.
GROUNDING: THE UNIT MUST BE ELECTRICALLY GROUNDED IN ACCORDANCE WITH
LOCAL CODES AND THE NATIONAL ELECTRICAL CODE.
