Wire the sander to a grounded, metal-enclosed
wiring system in accordance with the
requirements of the National Electric Code.
Consult the electrical schematics on pages 30
and 31 for clarification.
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 (see Figure 6). 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. Use only
three wire extension cords that have three-prong
grounding plugs and three-pole receptacles that
accept the tool’s plug.
Repair or replace a damaged or worn cord
immediately.
Make sure the voltage of your power supply
matches the specifications on the motor plate of
the Edge Sander.
230 Volt Operation
The Model OES9138 Edge Sander single
phase unit is designed to run on 230 volt power
only.
The three phase unit is pre-wired for 230 volt
power, but can be converted to 460 volt if so
desired (see “Converting to 460 Volt” below).
For 230 volt operation, you may either connect a
UL/CSA listed 230V plug (similar to the one
shown in Figure 7) or “hard-wire” the machine
directly to a control panel. If hard-wired to a
panel, make sure a disconnect is available for
the operator. The edge sander must comply with
all local and national codes after being wired.
1. If it is to be hard-wired, make sure the fuses
have been removed or the breakers have
been tripped in the circuit to which the Edge
Sander will be connected. Place a warning
placard on the fuse holder or circuit breaker
to prevent it being turned on while the
machine is being wired.
2. Refer to “Electrical Connections” on pages
30-32, for connecting the motor leads.
3. The Edge Sander with a 230 volt plug
should only be connected to an outlet
having the same configuration. No adapter
is available or should be used with the 230
volt plug.
