n
Warning
All units should be connected to a grounded power
supply system.
n
Warning
This appliance must be grounded and all field wiring
must conform to all applicable local and national
codes. Refer to rating plate for proper voltage. It is the
responsibility of the end user to provide the disconnect
means to satisfy the authority having jurisdiction.
n
Warning
All electrically operated appliances must be electrically
grounded in accordance with local codes, or in the
absence of local codes, with national electric code,

VOLTAGE
All electrical work, including wire routing and
grounding, must conform to local, state and national
electrical codes. The following precautions must be
observed:
• The equipment must be grounded.
• A separate fuse/circuit breaker must be provided
for each unit.
• A qualified electrician must determine proper
wire size dependent upon location, materials
used and length of run (minimum circuit ampacity
can be used to help select the wire size).
• The maximum allowable voltage variation is ±10%
of the rated voltage at equipment start-up (when
the electrical load is highest).
• Check all green ground screws, cables and wire
connections to verify they are tight before start-
up.
