Important Safety Information

·Read all instructions thoroughly and be familiar with the equipment before installing or working on it.

·Before connecting or disconnecting cables or other electrical connections, verify that the electrical

power to the system is removed. Failure to comply may cause serious damage to the motor

or injury.

·Because of the risk of electric shock, only individuals thoroughly trained in the use of multimeters

should conduct voltage tests.

·Never touch the metal contacts on the multimeter during a test.

·Always check testing equipment for proper operation before use.

Installation, operation, and maintenance must be performed by qualified personnel. Familiarization with

and adherence to the National Electrical Code (NEC), National Fire Protection Association (NFPA)

standards and to local codes are required. It is important to observe safety precautions to protect

personnel from possible injury. Personnel should be instructed for handling each of the following:

·Only apply nameplate voltage (115 or 230) with the Voltage Selection Switch in the correct position.

·Insulate all connections carefully to prevent grounding or short circuits. Reinstall all conduit and

terminal box covers.

·To avoid overheating or loss of output power, voltage to the motor control unit must be within plus

or minus 10% of the nameplate voltage.

·Make sure the unit is electrically grounded and that proper electrical installation, wiring, and

controls are used consistent with local and national electric codes. Refer to NEC Handbook and

NFPA No. 70. Employ qualified electricians for the installation and maintenance of the unit.

·Code requirements differ from state to state. Install equipment using qualified electricians

in accordance with the applicable codes and ordinances in your area and in accordance with NEC.

All electrical connections should be made and maintained by a qualified or licensed electrician.

·Make sure there are no unusual noises or vibrations when the motor is running.

·Avoid contact with energized circuits and rotating parts.

·Provide proper safeguards for personnel against rotating parts.

I n s t a l l a t i o n a n d O p e r a t i o n M a n u a l 2

·Always disconnect electrical power at the fuse box or circuit breaker panel before handling electrical

connections or performing maintenance on this unit. Allow the motor to come to a complete stop

and wait two (2) minutes. This allows the capacitors to discharge any residual voltage.

·All aspects of the installation must conform to the applicable requirements of the NEC, including

Article 430 (Motor Circuits and Controllers), as well as all local codes.

·Double-check to make sure that electrical power is removed and that it cannot be turned on while

you are working on the equipment.

·A poor electrical connection can overheat and cause terminal and/or terminal board failures.

Examine the connections carefully for any signs of physical deterioration or loose fit to the motor

terminal block.

·Care must be taken to assure connections are made to the proper terminals and adequate electrical

clearances are maintained.

·The control unit on the motor contains hazardous voltage.

·Wear safety glasses to inspect the equipment while it is running or while working on equipment.

The motor and control unit are assembled and calibrated as a set. There are no serviceable parts in the

motor or control.

·Do not lift the Neptune™1.25HP motor by the electronic control.

·To prevent permanent damage to the unit, only apply nameplate voltage.

·Do not strike the motor shaft with a hammer or other tool as this may cause damage.

·Voltage symbols vary among different multimeters and may be displayed as Vac, AC, V, or a V

beneath a wavy line. Select the correct symbol and set the multimeter to the voltage closest to but

higher than the voltage you are measuring.

·Although designed for outdoor application, the Neptune™1.25HP motor is properly packaged for

shipment and storage and should be kept in a clean and dry indoor area until installed for use.
