Note 1: The two terminals [L] are electrically connected together inside the inverter.
Note 2: We recommend using [L] logic GND (to the right) for logic input circuits and [L]
analog GND (to the left) for analog I/O circuits.
Note 3: Refer to page 39 for details of Alarm signals.

Note: If relay is connected to intelligent output, install a diode across the relay coil
(reverse-biased) in order to suppress the turn-off spike.
Caution for intelligent terminals setting
In turning on power when the input to the intelligent terminals become the following operations,
the set data might be initialized.
Please ensure not becoming the following operations, in changing the function allocation of the
intelligent input terminal.
1) Turning on power while [Intelligent input terminal 1/2/3 are ON] and [Intelligent input
terminal 4/5/6/7 are OFF].
2) After 1)'s condition, turning off power.
3) After 2)'s condition, turning on power while [Intelligent input terminal 2/3/4 are ON]
and [Intelligent input terminal 1/5/6/7 are OFF].
