7.0 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.
A power plug is not provided with this table saw. You
may either connect the proper UL/CSA listed plug or
"hardwire" the machine directly to your electrical
panel provided there is a disconnect near the
machine for the operator. Consult electrical
drawings in sect. 15.0 for further clarification of
wiring setup.
Before connecting to power source, be sure switch
is in off position.
It is recommended that the 3HP 1-phase, and 5HP
3-phase table saws be connected to a dedicated 20-
amp circuit with breaker or fuse.
The 5HP 1-phase saw should be connected to a 30-
amp circuit with breaker or fuse.
If connected to a circuit protected by fuse, use time
delay fuse marked "D". Local codes take
precedence over recommendations.

7.1 Grounding Instructions

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. A plug is not provided. A proper UL/CSA
listed plug may be installed or the machine may be
"hard-wired" to a circuit panel. If hard-wired, make
sure a disconnect is available to the operator.
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.
replacement of the electric cord or a plug is
necessary, do not connect the equipment-grounding
conductor to a live terminal.
Check
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.
Repair or replace damaged
immediately.

7.2 Voltage Conversion (3-phase
model only)
1. Remove transformer cover at back of machine
and move fuse from 230V position to 460V
position on transformer.
2. Switch the incoming power leads to the motor
for 460-volt operation, according to wiring
diagram on inside cover of motor junction box.
A similar diagram is found in sect. 15.0 of this
manual. (In case of discrepancy, diagram in
junction box takes precedence.)
3. Replace the 230V overload relay with a 460V
overload relay (additional purchase, part
number PM2000B-2107BORA).
4. If using a plug, the 230V plug must be replaced
with a UL/CSA listed plug rated for 460V.

7.3 Extension Cords

USE PROPER EXTENSION CORD. Make sure
your extension cord 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 3
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.
