Terminal Name
OI Analog current input
O Analog voltage input
H +10V analog reference
SP, SN Serial communication terminal
AL0, AL1, AL2 *3 Relay common contact
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.
