Electrical Requirements
1. All installation must conform to the National Electrical Code and all applicable local codes and ordinances.
2. A means for disconnection must be incorporated in the fixed wiring in accordance with the wiring rules.
RISK OF ELECTRICAL SHOCK OR ELECTROCUTION.
Variable Speed Pump must be installed by a
licensed electrician or a qualified service professional. All installation must conform to the National
Electrical Code and all applicable local codes and ordinances. Improper installation will cause electrical
hazards, which could cause death or serious injury of users, installers or others due to electric shock, and
may also cause property damage.
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 and safety 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 230V, 50 or 60Hz single phase input power. The terminal block connections are capable of handling
up to 12AWG 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 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
piping 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.
