Power Connection; Test Run - Grizzly G0827 Owner's Manual

Power Connection

Electrocution or fire can occur
if machine is ungrounded,
incorrectly connected to
power, or connected to an
undersized circuit. Use an
electrician or a qualified ser-
vice personnel to ensure a
safe power connection.
Before the machine can be connected to the
power supply, there must be an electrical cir-
cuit that meets the Circuit Requirements on
Page 14, and the correct plug must be installed
according to the instructions and wiring diagrams
provided by the plug manufacturer.
If the plug manufacturer did not include instruc-
tions, the wiring of a generic NEMA 15-15 plug is
illustrated in the Wiring section on Page 64.
To minimize the risk of electrocution, fire, or equip-
ment damage, installation work and electrical wir-
ing MUST be done by an electrician or qualified
service personnel.
Note About Extension Cords: Using an incor-
rectly sized extension cord may decrease the
life of electrical components on your machine.
Refer to Extension Cords on Page 15 for more
information.
Note About Phase Converters: Avoid using a
static phase converter to supply 3-Phase power
for this machine, as it could damage or decrease
the life of sensitive electrical components. If you
must use a phase converter, only use a rotary
phase converter that is sized at least 50% larger
than the highest HP rating of this machine. If
using a phase converter to supply power, only
connect the manufactured leg or "wild wire" to the
L2 terminal (see location on Page 67). The L2
terminal can handle power fluctuations because it
is wired directly to the motor.

Test Run

Once assembly is complete, test run the machine
to ensure it is properly connected to power and
safety components function properly.
If you find an unusual problem during the test run,
immediately stop the machine, disconnect it from
power, and fix the problem BEFORE operating the
machine again. The Troubleshooting table in the
SERVICE section of this manual can help.
Serious injury or death can result from
using this machine BEFORE understanding
its controls and related safety information.
DO NOT operate, or allow others to operate,
machine until the information is understood.
DO NOT start machine until all preceding
setup instructions have been performed.
Operating an improperly set up machine
may result in malfunction or unexpect-
ed results that can lead to serious injury,
death, or machine/property damage.
The test run consists of verifying following:
• Vertical spindle motor runs correctly
• Vertical spindle turns forward (clockwise)
when viewed from top of headstock
• Horizontal spindle motor runs correctly
• E-STOP button and rear column cover safety
switch work correctly
• Lamp works correctly
• Coolant system works correctly
• Power feed units work correctly
