Electrical connections
All electrical connections
must be done by a qualified electrician in
compliance with all relevant codes and
ordinances. Failure to comply may result in
serious injury.
The JDC-510 Dust Collector is rated at 230 volt,
single phase only, and is provided with a 6-20P
plug designed for use on a circuit with a
grounded outlet that looks like the one pictured
in Figure 5-1.
Before connecting to power source, be sure
switch is in off position.
It is recommended that the JDC-510 be
connected to a dedicated minimum 20 amp
circuit with circuit breaker or time-delay fuse
marked “D”.
Local codes take precedence
over recommendations.

GROUNDING INSTRUCTIONS
1. All Grounded, Cord-connected Tools:
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 pe
r
sonnel 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
between
150 - 250 volts
, inclusive:
This tool is intended for use on a circuit that has
an outlet that looks like the one illustrated in
D,
Figure 5-1. 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.

Extension cords
The use of extension cords is discouraged; try to
position equipment within reach of the power
receptacle. If an extension cord becomes
necessary, be 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 recommended 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.
