Powermatic PM1300 - Manual (Page 12)

Electrical Connections
Electrical connections must
be made by a qualified electrician in
compliance with all relevant codes. This
machine must be properly grounded to help
prevent electrical shock and possible fatal
injury.
The PM1300 is equipped with a single phase,
115/230 volt motor. It is factory wired for 115
volts. Keep in mind that a circuit being used by
other machines (tools, lights, heaters, etc.) at
the same time will add to the electrical load.
Thus, it is recommended that the machine be
connected to a dedicated circuit, with a 30 amp
circuit breaker or fuse for 115 volt operation; and
a 20 amp circuit breaker or fuse for 230 volt
operation. Local codes will take precedence
over recommendations.
The dust collector can be re-wired for 230V
operation as follows:
To convert to 230 volt operation:
1. Disconnect from power source; unplug!
2. Connect the motor leads as shown in the
diagram inside the motor junction box; this
diagram is also shown on page 21 of this
manual.
3. Open the control box cover by removing the
six screws, and move the voltage switch to
230V.
4. Replace the plug on the power cord with an
appropriate UL/CSA listed 230V plug.
5. When finished wiring, re-install junction box
and control box covers.
Grounding Instructions
This machine must be grounded. In the event of
a malfunction or breakdown, grounding provides
a path of least resistance for electric current to
reduce the risk of electric shock.
Improper connection of the equipment-
grounding conductor can result in a risk of
electric shock. The conductor with insulation
having an outer surface that is green with or
without yellow stripes, is the equipment-
grounding conductor. If repair or replacement of
the electric cord or plug is necessary, do not
connect the equipment-grounding conductor to a
live terminal.
The hose or ductwork you use to connect the
tool to the dust collector must also be grounded.
Make sure the voltage of your power supply
matches the specifications on the motor plate of
the dust collector.
Check with a qualified electrician or service
personnel if the grounding instructions are not
completely understood, or if in doubt as to
whether the tool is properly grounded.
Repair or replace a damaged or worn cord
immediately.
Extension Cords
If an extension cord is needed, make sure the
cord rating is suitable for the amperage listed on
the machine’s motor plate. An undersize cord
will cause a drop in line voltage resulting in loss
of power and overheating.
Use the chart in Figure 11 as a general guide in
choosing the correct size cord. If in doubt, use
the next heavier gauge. The smaller the gauge
number, the heavier the cord.

Overload Re-set
If the Dust Collector overloads during operation,
press the re-set switch on the motor, shown in
Figure 12. Then re-start the machine.
