Warning
n
The machine must be wired and grounded in
accordance with national and local electrical codes.
Minimum Circuit Ampacity
The minimum circuit ampacity is used to help select the wire
size of the electrical supply. (Minimum circuit ampacity is not
the N2Fusion System’s running amp load.) The wire size (or
gauge) is also dependent upon location, materials used, length
of run, etc., it must be determined by a qualified electrician.
Voltage
A dedicated electrical circuit is required, a power cord is
provided with all units. Some models are available in different
voltages and may be equipped with a different plug.
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.
