Terminal Connection Diagram

Sink logic
*1. DC reactor (FR-HEL)
Be sure to connect the DC reactor
Main circuit terminal
supplied with the 75K or more.
Control circuit terminal When a DC reactor is connected to
the 55K or less, remove the jumper
across P1-P/+.
Three-phase AC
power supply
*2. To supply power to the
control circuit separately,
remove the jumper across
R1/L11 and S1/L21.

when the frequency setting signal
is changed frequently.
CAUTION
⋅
To prevent a malfunction caused by noise, separate the signal cables more than 10cm from the power cables.
⋅
Be sure to earth (ground) the inverter and motor before use.

This connection diagram assumes that the control circuit is sink logic (initial setting). Refer to the instruction manual for the connection in the case of
source logic.
