Operation
The Model W1756/W1757 is prewired for 220V 3-phase
operation, but may be rewired for 440V 3-phase operation
(see Pages 15 & 54).
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.

Electrical Specifications
Phase Converter
The power from the manufactured power leg (wild wire)
of a phase converter
fluctuates, which may damage
electrical components if connected to the wrong incoming
power terminal. If you must use a phase converter for
3-phase power, only connect the
L2 "wild wire" to the S
terminal (See Page 50
).
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.
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 "Test
Run" portion of this manual.
TURN OFF and LOCK your
master power switch so
no power is available
to the sander before
connecting electrical
wires! If you ignore
this warning serious
electrical shock may
occur causing injury or
death!
OFF
This machine must be
grounded! If you have
any questions about
correct electrical
installation, contact a
qualified electrician for
assistance to make sure
all connections are safe
and adhere to your local
electrical codes.
