Extension Cords; 230 Volt, Single Phase Operation; Three Phase Operation - Powermatic PJ-882 Manual De Operación Y Partes

Extension cords

The use of an extension
recommended for the PJ882 Jointer. But if one
is necessary, make sure the cord rating is
suitable for the amperage listed on the
machine's motor plate. An undersized cord will
cause a drop in line voltage resulting in loss of
power and overheating.
Use the chart in Figure 8 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.

230 Volt, Single Phase Operation

As received from the factory, the single-phase
model of the PJ-882 Jointer is designed to run
on 230 volt power only.
The jointer has a grounding plug that looks like
the plug illustrated in Figure 9; or you may
choose to "hard-wire" the machine directly to a
control panel. If hard-wired to a panel, make
sure a disconnect is available for the operator.
The Jointer must comply with all local and
national codes after being wired.
If the Jointer is to be hard-wired, make sure the
fuses have been removed or the breakers have
been tripped in the circuit to which the Jointer
will be connected. Place a warning placard on
the fuse holder/circuit breaker to prevent it being
turned on while the machine is being wired.
The Jointer with a 230 volt plug should only be
connected to an outlet having the same
configuration. No adapter is available or should
be used with the 230 volt plug.
It is recommended that the single phase jointer
be connected to a dedicated, minimum 20 amp
circuit with a 20 amp circuit breaker or time
delay fuse. Local codes take precedence over
recommendations.

Three Phase Operation

The three-phase model is factory wired for 230
volt, but can be converted to 460 volt if so
desired (see "Converting From 230 Volt to 460
Volt").
"Hard-wire" the machine directly to a control
panel and make sure a disconnect is available
for the operator.
If you are hard-wiring the Jointer, make sure the
fuses have been removed or the breakers have
been tripped in the circuit to which the Jointer
will be connected, and place a warning placard
on the fuse holder or circuit breaker to prevent it
being turned on until wiring is complete.

It is recommended that the three phase jointer,
when operated at 230 volts, be connected to a
dedicated, minimum 20 amp circuit with a 20
amp circuit breaker or time delay fuse. When
operated at 460 volts, connect the jointer to a
dedicated, minimum 15 amp circuit with 15 amp
circuit breaker or time delay fuse. Local codes
take precedence over recommendations.
Converting from 230 Volt to 460 Volt
(Three Phase Only)
Consult the wiring diagram inside the starter box
cover. A diagram is also included on page 46 of
this manual. The Jointer must comply with all
local and national codes after being wired.
1. Replace the current contactor with the 460V
2. Re-connect the incoming leads to the motor
3. If using a plug, install a proper UL/CSA listed
