RISK OF ELECTRICAL SHOCK OR ELECTROCUTION. The SuperMax
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 SuperMax VS Variable Speed 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. The 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.
