Electrical connections
Electrical connections should
be made by a qualified electrician in compliance
with all relevant codes. Failure to comply may
cause serious injury.
The PM1250 Electrostatic AFS is prewired for single
phase, 120V power. It is provided with a plug
designed for use on a circuit with a grounded outlet
that looks like the one pictured in Figure 5-1.
It is recommended that the PM1250 be connected
to a dedicated 15 amp circuit with circuit breaker or
fuse. If fuses are used, they should be time-delay
fuse marked “D”.
Local codes take precedence
over recommendations.
IMPORTANT:
This electrostatic unit must be
electrically grounded for proper operation, as well as
for safety reasons (see below).

GROUNDING INSTRUCTIONS
1. All Grounded, Cord-connected Tools:
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. This tool is equipped with
an electric cord having an equipment-grounding
conductor and a grounding plug. The plug must be
plugged into a matching outlet that is properly
installed and grounded in accordance with all local
codes and ordinances.
Do not modify the plug provided - if it will not fit the
outlet, have the proper outlet installed by a qualified
electrician.
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.
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. Failure to comply may cause serious
or fatal injury.
Use only 3-wire extension cords that have 3-prong
grounding plugs and 3-pole receptacles that accept
the tool's plug.
Repair or replace damaged or worn cord
immediately.
2. Grounded, cord-connected tools intended for use
on a supply circuit having a nominal rating less than
150 volts:
This tool is intended for use on a circuit that has an
outlet that looks like the one illustrated in Figure 5-
1.
Figure 5-1
5.2
Extension cords
The use of extension cords is discouraged. Try to
position machines within reach of the power source.
If an extension cord must be used, make sure it is
heavy enough to carry the current your product will
draw. An undersized cord will cause a drop in line
voltage resulting in loss of power and overheating.
Table 2 shows correct size to use depending on
cord length and nameplate ampere rating. If in
doubt, use the next heavier gauge. The smaller the
gauge number, the heavier the cord.
