The machine must be properly set up before it is
safe to operate. DO NOT connect this machine to the
power source until instructed to do so in the "Power
Connection" portion of this manual.
W1773 220V/440V 3-
Phase Operation
The Model W1773 is prewired for 220V 3-phase operation,
but may be rewired for 440V 3-phase operation (see Page
13).
This machine must be hardwired to a locking shutoff
switch by a qualified electrician. Hardwiring involves a
permanent installation with conduit runs that can only be
accomplished safely by a qualified electrician. As always,
observe all applicable electrical codes when connecting
this machine to power.
This machine must be grounded! Verify the ground before
connecting this machine to the power source.
Phase Converter
The power from the manufactured power leg (wild wire)
of a phase converter fluctuates, which may damage elec-
trical components if connected to the wrong incoming
power terminal. If you must use a phase converter for
3-phase power, only connect the "wild wire" to the L1
terminal. The wire from the L1 terminal can handle some
fluctuation because it goes directly to the motor. The
power going to the L2 and L3 terminals connects to the
controls and must be consistent to prevent damage.
