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

If relay is connected to intelligent output, install a diode across the relay coil
Note:
(reverse-biased) in order to suppress the turn-off spike.
