General Precautions
WARNING
• All power wiring and communication cable installation must be performed by authorized service providers working in accordance with local,
state, and National Electrical Code (NEC) regulations related to electrical equipment and wiring, and following the instructions in this manu-
al. Failure to do so will lead to electric shock and bodily injury or death.
• Undersized wiring will lead to unacceptable voltage and will cause a fire, which will cause bodily injury or death.
• Ensure that all power wiring / communication cables are properly terminated and firmly attached. If power wires and communication cables
are not properly terminated and firmly attached, there is risk of fire, electric shock, and physical injury or death.
• Do not install the wiring in reversed phase or missed phase. Connect all wires appropriately. If the system operates in reversed phase
or missed phase, it will result in a fire, electric shock, and will cause physical injury and / or death.
• Install appropriately sized breakers / fuses / overcurrent protection switches and wiring in accordance with local, state, and NEC regulations
related to electrical equipment and wiring, and following the instructions in this manual. Generated overcurrent could include some amount
of direct current. Using an oversized breaker or fuse will result in electric shock, physical injury or death.
• Familiarize yourself with the location of the circuit breaker. Be sure that a circuit breaker or some other emergency power cutoff device is in
place before any power wiring is done to the system. Failure to do so will cause bodily injury or death.
• Be sure that main power to the unit is completely off before proceeding. Follow all safety and warning information outlined at the beginning
of this manual. Failure to do so will cause electric shock and bodily injury.
• Never touch any power lines or live cables before all power is cutoff to the system. To do so, will cause bodily injury or death.
• Properly ground the / all chillers. Ground wiring must always be installed by a qualified technician. Ground wiring is required to prevent
accidental electrical shock during current leakage, which will cause bodily injury or death.
• Properly ground the chillers.
wiring; or to the building plumbing system. Ground wiring must always be installed by a qualified technician. Failure to properly provide a
NEC-approved earth ground can result in electric shock, physical injury or death.
• Properly ground the / all chiller/s. Ground wiring must always be installed by a qualified technician. Improperly ground wire can cause com-
munication problems from electrical noise, and motor current leakage.
• Do not install the wiring in reversed phase or missed phase. Connect all wires appropriately. If the system operates in reversed phase
or missed phase, it will damage the compressors and other components.
• Install appropriately sized breakers / fuses / overcurrent protection switches and wiring in accordance with local, state, and NEC regulations
related to electrical equipment and wiring, and following the instructions in this manual. Generated overcurrent will include some amount of
direct current. Using an oversized breaker or fuse will result in equipment malfunction and property damage.
• Do not connect ground wire to refrigerant, gas, or water piping; to lightning rods; to telephone ground wiring; or to the building plumb-
ing system. Failure to properly provide a NEC-approved earth ground can result in property damage and equipment malfunction.
• Verify the power imbalance is no greater than 2% between phases at each unit. Power imbalances will damage the compressors and other
components.
