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.

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.
a malfunction or breakdown, grounding provides
a path of least resistance for electric current to
reduce the risk of electric shock.
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
personnel if the grounding instructions are not
completely understood, or if in doubt as to
whether the tool is properly grounded. Repair or
replace a damaged or worn cord immediately.

It is recommended that the single-phase belt
grinder be connected to a dedicated, minimum
50 amp circuit with a 50 amp circuit breaker or
time-delay fuse; the three phase belt grinder (at
230 volt operation) be connected to a dedicated
minimum 30 amp circuit with a 30 amp circuit
breaker or time delay fuse; and the three phase
belt grinder (at 460 volt operation) be connected
to a dedicated, minimum 15 amp circuit with 15
amp circuit breaker or time delay fuse. Local
codes take precedence over recom-
mendations.

7.4 Voltage Conversion (3PH only)
To convert the 3-phase belt grinder from 230 to
460 volt operation:
460 volt operation:
1. Switch the incoming power leads according
to the diagram inside the motor junction box.
Similar diagrams are found in Section 13 of
this manual. (In case of discrepancy, the
diagrams in the motor junction box will take
precedence.)

2. Make sure connections to transformer are
suitable for the new voltage.
3. If a plug is being used, install a UL/CSA
listed plug suitable for 460 volt operation.
