DO NOT connect 220V power or a ground or neutral to the center terminal of the Phase-A-Matic static converter as the resulting dead short will damage it instantly. The single-phase neutral wire is not required for operation of the converter. Properly ground all electrical equipment. Use a grounding clip to attach the ground wire to the conduit box. Resistive or single-phase loads must only be connected to lines A and C. This product is designed for indoor use only. Do not use in wet or damp locations. Do not mount on equipment with excessive vibration.

The red indicator light should only come on when the motor is starting, and should go out once the motor has reached operating speed. The light should never stay on longer than 3-5 seconds since the converter could be damaged if it stays on longer. When testing the converter for the first few times after installation, keep your hand near the off switch to prevent damage to the converter due to a wrong or loose connection.

For machines with magnetic switch gear, DO NOT connect the Phase-A-Matic static converter until you identify which two wires operate the magnetics. To easily locate these two wires, connect 220V single-phase power to any 2 of the 3 wires on the machine, and press the start button. When the correct combination is found the magnetics will work. Connect these two wires to the outside terminals of the converter, lines A and C, and the third wire to the center terminal, line B. The magnetics should still work with the center terminal, line B, disconnected.

The horsepower of the first motor to start, or Idler Motor if used, must fall within the minimum and maximum HP range on the converter. However, after the first motor, or Idler Motor, has started, motors below the minimum range may then be started and can usually be left running as the main motor is stopped and started.

Always start a machine out of gear or in lowest spindle speed at initial hook-up to reduce load. The Phase-A-Matic static phase converter has a built-in weak link which is designed to fail rapidly if hooked to a higher horsepower motor. On a lower horsepower motor the light could stay on after the motor is running, which would cause rapid failure of the converter, thus providing protection against possible motor damage.

Fuses should not be used between the Phase-A-Matic static phase converter and the motor. A blown fuse still leaves two lines to conduct which can damage the converter. Magnetic starters are preferred. If fuses are used, they should be placed on the single-phase lines L1 and L2.

Using the Phase-A-Matic static phase converter as in "Method Number 1" will produce approximately 2/3 of the rated horsepower.

Heavily loaded applications, such as compressors, blowers, water pumps, hydraulic pumps, etc., the motor pulley diameter must be reduced by 1/3, or a 50% larger motor must be fitted. Otherwise, "Method Number 2", the Idler Motor System, could be used. Or, use our Phase-A-Matic Rotary Converter.

Power may be left on the converter without the load applied. Current draw is approximately 8mA (.008 amp). The converter operates best when mounted vertically with the conduit box on top. Installation should be performed by a qualified electrician. Refer to local codes for proper wire sizing. Wires should be sized as appropriate for the motor's rated amperage. This unit is not recommended for use with phase-loss monitors.
