orientations.
Liability
The installation must always be designed and made according to applicable local laws and
regulations. ABB does not assume any liability whatsoever for any installation which
breaches the local laws and/or other regulations.
Switching, disconnecting and protecting solution
To arrange the switching, disconnection and protection of the ACS880-04, you can use the
following solutions.
The switching, disconnecting and protecting equipment can be placed outside the drive
cabinet in the following way:
1. The AC supply is first connected to the main switch-disconnector [Q1.1] or main circuit
breaker [Q1].
2. The AC fuses are connected after the switch-disconnector.
3. The main contactor [Q1.2] is connected between the AC fuses and the supply module.
For the connection diagram, see chapter Electrical installation.
