Dust Collection; Grounding Instructions - Powermatic DS20 Operating Instructions And Parts Manual

Dust Collection

The use of a dust collection system with the
Disc Sander is strongly recommended. It will
maintain shop cleanliness, and help prevent
possible health hazards caused by wood dust.
Make sure the capacity of the dust collector is
suitable for this size machine. Minimum 600
cubic feet per minute is recommended.
The Disc Sander has a 4" diameter dust port
(Figure 2). Slide the hose of your dust collector
over the outlet, and secure with a hose clamp.
NOTE: Dryer vent hose is not acceptable for this
purpose.

Grounding Instructions

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.
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 to the operator.
Improper connection
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,
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.
Single Phase Connections
The single phase Sander is factory wired for 230
volts only. It is not supplied with a plug. You may
either install a UL/CSA-listed plug suitable for
230 volt operation, or "hard-wire" the Sander
directly to a service panel (make sure a
disconnect is available for the operator).
It is recommended that the single phase Sander
be connected to a grounded and dedicated,
minimum 30 amp circuit with a 30 amp circuit
breaker or time delay fuse. Local codes take
precedence over recommendations.
Disc Rotation (Single Phase Only)
The single phase model can be wired to allow
disc rotation in either direction. If you wish to
change disc direction, refer to the diagram
inside the motor junction box. This diagram is
repeated in Figure 3.
