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 trip 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.
