RISK OF ELECTRICAL SHOCK OR ELECTROCUTION. The Variable Speed Pump must be installed by a licensed or certified
electrician or a qualified service professional in accordance with the National Electrical Code and all applicable local codes and
ordinances. Improper installation will create an electrical hazard which could result in death or serious injury to users, installers, or
others due to electrical shock, and may also cause damage to property.
Always disconnect power to the pump at the circuit breaker before servicing the pump. Failure to do so could result in death
or serious injury to service people, pool users or others due to electric shock and/or property damage.
Read all servicing instructions before working on the pump.

Wiring Overview and Installation

Power should be turned off when installing,
servicing, or repairing electrical components.
Observe all warning notices posted on the existing equipment, pump,
and in these installation instructions.
The pump must be wired according to the local electrical
codes and standards. Always refer to the National Electrical
Code. This pump should be installed by a licensed
electrician.
The pump accepts 99-253V, 50 or 60Hz single phase input
power. The terminal block connections are capable of
handling up to 10AWG solid or stranded wire. There are
also fast-on type quick connectors, however, check the local
electrical codes for the desired connection method.
connections must be permanently made to the grounding
terminal (see Figure 3) in the field wiring compartment
according to the local electrical code. The motor controller
will automatically regulate the pump's speed when running
on lower voltage to keep the current below 13.2A. There is
no wiring change required to run the pump on 110V nominal
power, the same terminals are used as with high voltage
wiring.
The drive will operate on 2-phase Line-Line-Ground
electrical systems as well as Line-Neutral-Ground systems.
This pump must be permanently connected by a circuit
breaker as specified in the local electrical code.
1. Be sure all electrical breakers and switches are turned
off before wiring motor. Always wait five (5) minutes after
disconnecting the power from the pump before opening
or servicing the drive.
2. Choose a wire size for the pump in accordance with the
current National Electrical Code and all applicable local
codes and ordinances. When in doubt use a heavier
gauge (larger diameter) wire. Be sure the wiring voltage
is within the operating range.
3. Be sure all electrical connections are clean and tight.
4. Cut wires to the appropriate length so they do not overlap
or touch when connected to the terminal board.
5. Permanently ground the motor using the ground screw
located on the inside rear of the controller interface (see
Figure 3). Use the correct wire size and type specified by
the current National Electrical Code. Be sure the ground
wire is connected to an electrical service ground.
6. Bond the motor to all metal parts of the pool structure
and to all electrical equipment, metal conduit and metal
pipping within 5 feet (1.5 M) of the inside walls of the
swimming pool, spa or hot tub in accordance with the
current National Electrical Code. UL requires use of a
solid copper bonding conductor not smaller than 8 AWG.
See Figure 3.
Note: For Canada, a 6 AWG or larger solid copper
bonding conductor is required.
7. The pump should be permanently connected to either a
circuit breaker, 2-pole timer or 2-pole relay. If AC power
is supplied by a GFCI circuit breaker, use a dedicated
circuit breaker that has no other electrical loads.
8. Connect the pump permanently to a circuit. Make sure
no other lights or appliances are on the same circuit.

The field wiring compartment has a 1/2" NPT threaded
conduit port for the liquid tight fitting.
The bonding lug should be used to bond the motor
frame to the equipment pad.
