Grounding; Extension Cords; Rewiring To 110V - Grizzly G3616 Owner's Manual

Grounding

In the event of an electrical short, grounding
reduces the risk of electric shock. This tool is
equipped with a power cord that has a grounding
wire, which must be properly connected to the
grounding prong on the plug; likewise, the outlet
must be properly installed and grounded as well.
All electrical connections must be made in accor-
dance with local codes and ordinances.
Electrocution or fire could
result if this machine is
not grounded correctly or
if your electrical configu-
ration does not comply
with local and state codes.
Ensure
checking with a licensed
electrician!
This machine must have a ground prong in
the plug to help ensure that it is grounded.
DO NOT remove ground prong from plug
to fit into a two-pronged outlet! If the plug
will not fit the outlet, have the proper outlet
installed by a qualified electrician.

Extension Cords

220V Operation
We do not recommend the use of extension cords
on 220V equipment. Instead, arrange the place-
ment of your equipment and the installed wiring to
eliminate the need for extension cords.
110V Operation
If you find it necessary to use a 110V extension
cord:
• Make sure the cord is rated Standard Service
(grade S) or better.
• The extension cord must contain a ground
wire and plug pin.
• Use at least a 12 gauge cord that is 50 feet
long or less.

Rewiring to 110V

Regardless of these instructions, all rewiring must
be performed/inspected by a qualified electrician
before placing the machine into operation.
Before starting, you must order the 110V conver-
sion kit available for your machine. (G7947 110V
kit is #P7947600; G7948 110V conversion kit is
#P7948600.
To rewire the G3616/G3617 for 110V:
1. Rewire the spindle motor(s) and the coolant
motor as shown on the junction box cover on
each motor.
2. Replace the spindle motor relay(s) and the
coolant motor relay in the electrical control
box (see Pages 45 & 48) with the relays from
the conversion kit. Use the dial settings given
on Page to set the relays.
3.
Change the 220V wire on the transformer to
110V.
