6.0 Electrical connections
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.
The JWL-1840EVS and JWL-1840DVR lathes
require 230-volt single-phase input.
As received from the factory, the JWL-1840EVS
and JWL-1840DVR is ready to run at 230-volt
operation. This tool is intended for use on a circuit
that has an outlet that looks like the one illustrated
in Figure 6-1. The tool has a grounding plug that
looks like the plug illustrated in Figure 6-1. 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.
IMPORTANT: The JWL-1840EVS and JWL-
1840DVR Lathes cannot be run on a GFCI circuit.
Figure 6-1: grounding
Before connecting to power source, be sure switch
is in
off position.
It is recommended that the lathe be connected to a
dedicated 15 amp circuit with a circuit breaker or
fuse. If connected to a circuit protected by fuses,
use time delay fuse marked “D”.
Local codes
take precedence over recommendations.
6.1 GROUNDING INSTRUCTIONS
This tool 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 inserted into an appropriate
outlet that is properly installed and grounded in
accordance with all local codes and ordinances.
Improper connection of the
equipment-grounding conductor can result in a
risk of electric shock. Check with a qualified
electrician or service person if you are in doubt
as to whether the outlet is properly grounded.
Do not modify the plug provided with the tool –
if it will not fit the outlet, have a proper outlet
installed by a qualified electrician.
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.
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.
A lightning strike or power
surge may cause inverter failure. When lathe is
not in use, disconnect power plug, or have a 3-
or 4-pole disconnect installed on the power
side.
6.2 Extension cords
The use of extension cords is discouraged; try to
position equipment within reach of the power
source. 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 1 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.
