DRIVE 1
Relay Drive 1
Connect the ground side of an external relay coil here.
Relay operation is controlled by the FM 3617i/FM 3717i/FM 3817i and
is specified in Vehicle Properties of front end user software.
Coil current must not exceed 200mA

interruption
Connect to external relay coil, if starter interruption is required.
External coil current must not exceed 200mA.
NOTE: Do not interrupt starter circuit while current is flowing
(especially at higher voltages than 24V)
– the relay contacts may
undergo excessive wear, damage or arcing and fire may result.
