Protecting the drive and input power cables in short-circuits

￭

Cabinet-installed multidrives

To protect the input cable in short-circuit situations, install fuses or a suitable circuit
breaker at the supply side of the cabling.
The drive is equipped with fuses as standard. In case of a short-circuit inside the drive,
the fuses protect the drive, restrict drive damage, and prevent damage to adjoining
equipment.

Multidrive modules

To protect the input power cable in short-circuit situations, install fuses or a suitable
circuit breaker at the supply side of the cabling.
To protect the drive in short-circuit situations, install the ABB-specified fuses for the
supply unit, inverter units and other units. See the appropriate hardware manuals.
In additon, drive with ACS880-304LC...+A019 supply module: If you use parallel cables,
protect each cable against short-circuit individually. Obey the cabling and protection
instructions in ACS880-304LC...+A019 diode supply modules hardware manual
(3AXD50000045157 [English]).

Protecting the motor and motor cable in short-circuits

￭
The drive protects the motor cable and motor in a short-circuit situation when:
• the motor cable is sized correctly
• the motor cable type complies with the motor cable selection guidelines by ABB
• the cable length does not exceed the allowed maximum length specified for the
drive
• the setting of parameter 99.10 Motor nominal power in the drive is equal with the
value given on the motor rating plate.
The electronic power output short-circuit protection circuitry meets the requirements
of IEC 60364-4-41 2005/AMD1.
