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: Default relay N.O./N.C. configuration is reversed. See page 4-35.

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.
