(∗1) Among the inverters. assignment to the digital input terminals can be arbitrarily changed
in some inverters. Select the external alarm input by function setting.
(∗2) Do not short-circuit the not using terminals of the control PCB in the DB unit.
(∗3) The parallel connection of the DB units is up to two units.
When necessary to connect 3 or more DB units, contact us separately.
(∗4) Connect a lump-sum alarm output of the DB unit and braking resistor to the external alarm
input, and construct a sequence to open the electromagnetic contactor by the lump-sum
alarm output of the inverter.
