To Check For Proper Rotation – 3 Phase Motors
Risk of electrical shock.
1. Be sure power is disconnected to motor when
working on electrical connections.
2. Remove the motor end cover, exposing motor shaft.
Momentarily start pump. If hookup is correct, the
shaft will rotate clockwise.
3. If rotation is not clockwise, reverse any two leads to
the starter. The rotation will now be correct.
GROUNDING THE MOTOR
Ground the pump permanently using a wire of size and
type specified by local or National Electrical Code.
Models (HP7C-01 and HP7D Series Only) with
factory installed cord and plug:
Risk of electric shock.
This equipment is
only for use on 115V and is equipped with an approved
3-conductor cord and 3-prong, grounding-type plug. To
reduce the risk of electric shock, be certain that it is
connected to a properly grounded, grounding-type
receptacle. Do not modify or remove plug. Make sure
pump circuit meets National Electrical Code. To avoid
dangerous electrical shock hazard, keep cord dry at all
times.
Models without cord and plug:
1. Connect ground wire first. Connect the ground first,
then to green grounding terminal provided under
motor canopy (see Figures 5 and 6) identified as
GRD. Make ground connection to this terminal.
Do
not
connect motor to electrical power supply until
unit is permanently grounded; otherwise serious or
fatal electrical shock hazard may be caused.
2. For best ground connection, connect to a grounded
lead in the service panel or to a metal underground
water pipe or well casing at least 10 ft. long. If
plastic pipe or insulated fittings are used, run ground
wire directly to the metal well casing or use ground
electrode furnished by the power company.
