Power supply
Note: 1. To ensure safety, connect the power input to the inverter via a magnetic
contactor and earth (ground) leakage circuit breaker or no-fuse breaker, and
use the magnetic contactor to switch power on-off.
2. The output is three-phase 200V.

Connect to the commercial power supply. Keep these
terminals open when using the high power factor
converter (FR-HC) or power regeneration common
converter (FR-CV).
Connect a three-phase squirrel-cage motor.
Connect the optional brake resistor across terminals P-
PR (+ - PR) (not for 0.1K and 0.2K).
Connect the optional brake unit, high power factor
converter (FR-HC), and power regeneration common
converter (FR-CV).
Disconnect the jumper from terminals P-P1 (+ - P1) and
connect the optional power factor improving DC reactor.
(can not be connected to the single phase 100V power
input specification inverter)
For earthing (grounding) the inverter chassis. Must be
earthed (grounded).
