ELECTRICAL
DANGER
Check all wiring connections, including factory
terminals, before operation. Connections can become
loose during shipment and installation.
n
Warning
If the supply cord is damaged, it must be replaced by a
special cord or assembly available from the manufacturer
or its service agent.
n
Warning
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 N
2
Fusion 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.

Preparing the power cord (International units only)
The following instructions cover the installation of a 220
VAC, 50/60 Hz (international) unit. An appropriate 3-wire
power receptacle must be located within 6 ft (1.8 m) of the
unit. Unpack the unit from its transportation packaging and
visually check for any signs of damage.
NOTE: Only use an approved plug for the country in which
the unit is being installed.
Important
The wires in the power cord/mains lead are colored in
accordance with the following code:
• Green / Yellow = Ground/Earth
• Blue = Neutral
• Brown = Line/Live
1. Locate a 3-terminal plug. This plug (not furnished with
unit) must have a ground-wire-connecting terminal.
2. Locate the loose end of the power cord attached to
the unit. All three (3) wires are stripped to 1/2" (1.3 cm)
length from the end.
3. Connect all three (3) wires to the plug using the
1/2" (1.3 cm) stripped ends or any other terminal
requirements. Different plugs and terminals may
require different stripped lengths.
4. Inspect the cord and plug connection for any loose or
bare wires.
