codes. This includes local electrical codes which may
affect the connection and operation of the Wilton sander in
your specific manufacturing
operation.
Single Phase Electrical Hookup
When connecting your machine to single phase
power, you may be connecting to either 115 or 230 volts,
depending upon the motor type provided. Local codes
may, or may not, permit the use of a plug type of
connection for your machine. Where a plug connection is
permitted, the following installation practices must be
followed:
1. The plug used must be a grounding type of plug. That is,
on a 115 volt single phase connection, the plug must be a
three-prong plug with two flat, parallel blades for the
power wires and a single rounded or U-shaped prong for
the ground connection. On 230 volt single phase
connections, the lug must be a three prong plug with two
flat blades in tandem to carry the current, and a third
round or U-shaped prong for the ground connection.
2. The service branch to which the plug is connected must
be a branch with a separate ground wire so the grounding
prong of the plug can be connected to ground effectively.
Note: Local electrical codes in many jurisdictions
DO NOT ALLOW THE USE OF PLUG TYPE
CONNECTIONS FOR SINGLE PHASE POWER WHEN
THE MACHINE IS USED IN A COMMERCIAL OR
INDUSTRIAL ESTABLISHMENT.
In these cases you must connect your machine to
the service branch using a hardwired junction box
connection.
Motor Rotation
The motor should be turning counterclockwise, the
belt sander should be moving downward, and the disc
sander should be turning clockwise. These motors are
wired at the factory for correct rotation.
Voltage Conversion
Single phase machines are pre-wired for 115V or
230V per customer request. If it becomes necessary to
change the voltage, remove the back cover from the base
and place the machine on its side. Remove the terminal
cover from the motor. Rewire the motor according to the
motor connection diagram, Different electrical plugs are
required depending on which voltage you select. This
completes the voltage conversion process.
Circuit Protection
Where the service branch is protected with
overload
protecter
that has too high a value to offer protection to
the motor supplied,
overload protecter
box should be
used at the point where the machine connection is made
and the time delay
overload protecter
should be a
value just slightly higher than the maximum load current
draw.
Three Phase Electrical Hookup
1. Be certain the power to the branch you are connecting
is off and locked out, so power cannot be reestablished
accidentally.
2. Connect the ground wires. These wires will be either
green, or green with a white stripe.
