A power cord is not included, because this
machine must be permanently connected to the
power supply. A disconnecting means, such as
a locking switch (see
Figure
below), must be
provided to allow the machine to be disconnected
(isolated) from the power supply when required.
This installation must be performed by a qualified
electrician in accordance with all applicable elec-
trical codes and ordinances.
Serious injury could occur if you connect
the machine to power before completing the
setup process. DO NOT connect to power
until instructed later in this manual.
grounding instructions
In the event of a malfunction or breakdown,
grounding provides a path of least resistance
for electrical current to reduce the risk of electric
shock. A permanently connected machine must
be connected to a grounded metal permanent wir-
ing system; or to a system having an equipment-
grounding conductor. All grounds must be verified
and rated for the electrical requirements of the
machine. Improper grounding can increase the
risk of electric shock!
phase converter
When using a phase converter, the power from
the manufactured power leg (sometimes called
the wild wire) can fluctuate. Connect the manu-
factured power leg to the s terminal to prevent
damage to the transformer. the wire from the s
terminal can handle some fluctuation because it
goes directly to the motor. the power going to the
r and t terminals goes to the transformer and
must be consistent to prevent damage.
