ELECTRICAL INSTALLATION
Connect the proper power supply (check nameplate)
through a main line disconnect switch (not supplied)
to terminal connections L1, L2, L3 and ground into the
VPDB control cabinet that contains the motor starter.
This is the only power connection required since the
motor is pre-wired at the factory. See schematics with
this package. See FLA specification table below.
Connect control wiring from the conveying system
control panel, to the same electrical enclosure as shown
on the wiring schematic for the conveying system control
panel. Verify the correct rotation of the motor with the
directional labels on the pump assembly
