ELECTRICAL CONNECTION(S)
Electrical and grounding connections must comply with
applicable portions of the National Electrical Code (NFPA No. 70, latest edition)
and/or other local electrical codes.
Disconnect the electrical power to the machine and follow
lockout/tagout procedures. There may be multiple circuits. Be sure all circuits
are disconnected.
With power to all service connections locked out/tagged out, verify that the line and
load service connections have been properly tightened.
Refer to the electrical diagram located inside the control box door. Some machines
may require more than one electrical power supply connection. All electrical supply
lines to the machine must be disconnected when servicing machine.

Checking Motor Rotation (Three-Phase Motors)
Pumps, conveyor motor and blower dryer fan motors (when equipped) are all three-
phase motors. Before placing machine into service, check to verify correct rotation
by observing motor direction.
If any pump motor does not rotate in the correct direction, check the rotation of
the other motors. If they all are rotating backward, disconnect the electrical supply
and interchange any two of the incoming power supply leads. If all motors are not
running in the correct direction, only change the two incoming wires of the motor(s)
that is running backward. Reconnect electrical power, push the START switch and
verify that the motors rotate in the proper direction.
NOTE: If the conveyor motor does not rotate in the correct direction, disconnect
the electrical power supply and interchange any two of the conveyor motor wires
from the Frequency Inverter at terminal 8TB-1, -2, or -3.
