Control Logic Signal Specifications Section 4-3
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 4-5-11 Force Operation
from Digital Operator on page 188.

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.
