Ground motor before connecting to electrical
power supply. Failure to ground motor can cause
severe or fatal electrical shock hazard.

Figure 4 – Typical ground screw and bonding lug
locations.
Do not ground to a gas supply line.To avoid
dangerous or fatal electrical shock, turn OFF power
to motor before working on electrical connections.
Ground Fault Circuit Interrupter (GFCI) tripping
indicates an electrical problem. If GFCI trips and
will not reset, have a qualified electrician inspect and
repair electrical system.
Exactly match supply voltage to nameplate
voltage. Incorrect voltage can cause fire or
seriously damage motor and voids warranty. If in
doubt consult a licensed electrician.
Voltage
Voltage at motor must be not more than 10% above or
below motor nameplate rated voltage or motor may
overheat, causing overload tripping and reduced
component life. If voltage is less than 90% or more than
110% of rated voltage when motor is running at full
load, consult power company.

Grounding/Bonding
Install, ground, bond and wire motor according to local
or the current National Electrical Code requirements.
Permanently ground motor. Use green ground terminal
provided under motor canopy or access plate (See
Figure 4); use size and type wire required by code.
Connect motor ground terminal to electrical service
ground.
Bond motor to pool structure. Use a solid copper
conductor, size No. 8 AWG (8.4 sq.mm) or larger. Run
wire from external bonding lug (see Figure 4) to
reinforcing rod or mesh.
Connect a No. 8 AWG (8.4 sq.mm) solid copper
bonding wire to the pressure wire connector provided
on the motor housing and to all metal parts of the
swimming pool, spa, or hot tub and to all electrical
equipment, metal piping or conduit within 5 feet
(1.5 m) of the inside walls of the swimming pool, spa,
or hot tub.
