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 42 for details of trip signals.
Note 4: Refer to page 96, "Functional safety" for details

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
Please avoid conducting below procedure, because if you follow procedure describe below, the
inverter setting will be initialized.
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.
After 2)'s condition, turning on power while [Intelligent input terminal 2/3/4 are ON]
3)
and [Intelligent input terminal 1/5/6/7 are OFF].
