1 . VS-606PC3 INVERTER MAIN UNIT (Cont'd)
(6)
Wiring
(a) Main circuit input/output
(1) Phase rotation of input terminals Ll, L2, L3 is
available in either direction, clockwise or
counterclockwise .
(2) When inverter output terminals T1, T2, and T3 are
connected to motor terminals T1, T2, and T3,
respectively, motor rotates counterclockwise, when
viewed from opposite drive end, upon forward run
command. To reverse the .rotation, interchange any
two of the motor leads.
(3) Never connect AC main circuit power supply to
output terminals T1, T2, or T3 . Inverter may be
damaged.
(4) Care should be taken to prevent contact of wiring
leads with the VS-606PG3 cabinet, for a ground
fault or a short-circuit may result.
(5) Insert an L noise filter to the VS-606PG3 output, but
never connect power factor correction capacitor, LC
or RC to VS-606PG3 output.
(6) Be sure to tighten the main circuit terminal screws.
(7) Be sure to separate the main circuit wiring from
