POWER CONNECTIONS
A separate electrical circuit should be used for your machine. This circuit should not be less than #12 wire and
should be protected with a 20 Amp time lag fuse. Before connecting the machine to the power line, make sure the
electric current is of the same characteristics as indicated on the machine's specification plate. All line connections
should make good contact. Running on low voltage will damage the machine.
Do not expose the machine to rain or operate the machine in damp locations.
MOTOR SPECIFICATIONS
The 50-762 is wired to run on 230 volts, 60 HZ, but it can also be reconfigured to run on 460 volts. The 50-763 is
wired for 230 volts, 60 HZ.
This machine must be grounded while in use to protect the operator from electric shock.
The 50-762 and 50-763 dust collectors do not come with power cords and must be permanently connected to the
building’s electrical system and grounded according to the National Electrical Code. You CANNOT use extension cords
with these three-phase machines. For instructions on how to wire three-phase or single-phase motors, check the
section “SINGLE- AND THREE-PHASE WIRING” in this manual.
460 VOLT OPERATION
460 volt operation of the 50-762 requires replacement of the motor starter and reconfiguration of the motor's internal
connections. A 460 volt starter is available from most industrial electrical supply dealers and must be installed by a
qualified electrician.
DO NOT ATTEMPT to wire the machine for 460 volts without replacing the starter. Doing so will cause
damage to the machine and personal injury could result.
