4.2 Wiring and terminal description

ELB
Power source,
3-phase or
1-phase, per
inverter model
Refer to QRG (section 5.7) when using
external equipment for source logic
output and/or external power supply.
Intelligent inputs,
7 terminals
1kΩ～2kΩ
Note 1) Above shows an example of voltage (O) input. Changeover of SW6 must be done in case of current (OI) input. (Refer to page 9).

- Use [L1] and [N] terminal in case of 1-ph. 200V power supply
Connect 3-ph. motor
First, remove the short circuit bar between PD/+1 and P/+ terminal.
Then connect optional DC link choke for improving the input harmonics.
To make grounding. Be sure to make this grounding to avoid electric shock, and for improving
the EMC performance. The terminal is located on the heatsink.
