METHOD NO.1 INSTALLATION:
Static Phase Converter used to start the load motor
1. 220V single-phase lines L1 and L2 are connected to the A and
C terminals of the converter.
2. Do not connect 220V power, or a ground or neutral wire from
the utility, to the B terminal of the converter, as the resulting dead
short would damage it instantly. The single-phase neutral wire is
not required for operation of the converter.
3. Properly ground all electrical equipment for safety. Use a
grounding clip to attach the ground wire to the conduit box.
4. Fuses should not be used on the three-phase lines 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. Fuses
can be used on the single-phase lines L1 and L2 from the
utility power to the converter. Single-phase wires and fuses
should be sized as appropriate for the rated amperage of the
motor. See chart below.
5. Size the breaker on the single-phase approximately twice the
amperage rating of the motor at the 220V configuration. See
chart below.
6. For machines with magnetic switchgear, resistive or
single-phase load: Resistive or single-phase loads and/or
magnetic switchgear must be connected only to lines A and C
from the converter. DO NOT connect the PHASE-A-MATIC
static phase 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 PHASE-A-MATIC
converter, terminals A and C, and the third wire to the center
terminal, B. The magnetics should still work with the center
terminal (line B) disconnected. Your motor’s magnetic
overload protection remains the same; no changes are
necessary.
7. For indoor use only. Do not use in wet or damp locations.
8. Do not mount on equipment with excessive vibrations.
9. Refer to NEC Code #455 for details on field installation issues.
