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.

on a supply circuit having a nominal rating

150
volts:
This tool is intended for use on a circuit that has an
outlet that looks like the one illustrated in
A,
Figure
6-1. An adapter, shown in
B
and
C
, may be used to
connect this plug to a 2-pole receptacle as shown in
B
if a properly grounded outlet is not available. The
temporary adapter should be used only until a
properly grounded outlet can be installed by a
qualified electrician.
This adapter is not permitted in
Canada.
The green-colored rigid ear, lug, and the
like, extending from the adapter must be connected
to a permanent ground such as a properly grounded
outlet box.

, inclusive:
This tool is intended for use on a circuit that has an
outlet that looks like the one illustrated in
D,
Figure
6-1. The tool has a grounding plug that looks like the
plug illustrated in
D
. Make sure the tool is connected
to an outlet having the same configuration as the
plug. No adapter is available or should be used with
this tool. If the tool must be reconnected for use on
a different type of electric circuit, the reconnection
should be made by qualified service personnel; and
after reconnection, the tool should comply with all
local codes and ordinances.

Voltage conversion
To convert the dust collector to 230-volt power,
remove motor junction box cover and change the
incoming power leads, according to diagram affixed
inside cover. This diagram is also shown in Figure
6-2. NOTE: In case of discrepancy, diagram on
machine takes precedence.

Extension cords
The use of extension cords is discouraged; try to
position machines near the power source. If an
extension cord is necessary, make sure it is in good
condition. When using an extension cord, be sure to
use one 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 1 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.

Grounding wire information
A green grounding wire is connected to the base of
the dust collector, and can be used to connect to
dust hose or pipe systems to prevent static
electricity buildup. If you are using the DC-500P as
part of a larger shop system with hoses or PVC pipe,
you should seek further information from website
forums or experienced users as to proper and safe
methods for prevention of static electricity buildup.
