III Receiving, Handling, and Storage
1. Immediately upon receipt, carefully unpack and inspect the Controller for damage that may
have occurred in shipment. If damage or rough handling is evident, file a damage claim with
the transportation carrier.
2. If the Controller must be stored, cover it and place in a clean, dry location. Avoid unheated
locations where condensation can result in damage to the insulation or corrosion of metal
parts.
IV Installation
1. Consult the motor nameplate to determine voltage, current, and horsepower rating and
compare with the Controller nameplate for matching data.
2. Release the door interlock by moving the CIRCUIT BREAKER DISCONNECTING
MEANS to the OFF position.
3. Inspect the control transformer’s primary connections for agreement with the line voltage of
the incoming power.
4. Exercise all switches and contactors, without power, to see that they operate freely.
5. Choose a location or base for the Controller that is non-combustible and within site of the
motor. The base should not be subject to excessive vibration that may cause erratic operation
of the PS (pressure switch). The Controller should be leveled so that the PS is level. Sight
across the PS cover screws.
