CONNECTION TO THE MAIN POWER SUPPLY 6. CONNECTION TO THE MAIN POWER SUPPLY 6.1 ELECTRICAL Hazardous voltage. Can shock, burn, or cause death. Ground pump before connecting to power supply. Disconnect power at service panel before connecting motor. Ground motor before connecting to electrical power supply. Failure to ground motor can cause severe or fatal electrical shock hazard. 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. Match supply voltage to nameplate voltage. Incorrect voltage and/or wiring can cause fire or seriously damage motor and voids warranty. All electrical wiring, grounding, and bonding must be done by a licensed electrical contractor who is familiar with commercial swimming pool installations and electrical codes and requirements. HCP Series pumps must be installed by a licensed or certified electrician, or a qualified pool service person, in accordance with the National Electrical Code, as well as all applicable local codes and ordinances. Improper installation could create an electrical hazard, which could result in death or serious injury to pool users, installers or others due to electrical shock. Improper installation may also damage property. Before servicing the pump, disconnect power at the circuit breaker. Failure to disconnect power at the circuit breaker could result in death or serious injury. NOTICE Due to wide variation in electrical equipment, power supply, and installation requirements, this manual does not make specific recommendations concerning auxiliary equipment or fusing/wiring. Wire sizing, wire type, branch circuit fuse protection, motor starter, control equipment, and related items must meet National Electrical Code and local code requirements. Motors are supplied by several manufacturers and nameplate data (service factor, maximum amperage, etc.) will vary. Consult control manufacturer and motor nameplate on your pump to correctly choose and size motor starter and control equipment for your particular installation. Specific electrical questions or problems should be addressed to the manufacturer of the electrical component in question. 6.2 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. Do not try to connect 3-phase motors to single phase power supply or single phase motors to 3-phase power supply. 12
