Operation principle
The EMC C1 filter (+E223 or +F316) is used for EMC compliance, see page 13 .
The main switch-disconnector – called main switch in this supplement – (+F278 or
+F316) is used for switching off the input power of the drive and disconnecting the
drive securely from the AC power line.

Using the main switch-disconnector
To use the main switch:
1. Stop the drive.
2. Wait until the motor has stopped.
3. Turn the main switch to the OFF position.
4. Attach a lock to the main switch. This is essential if you must work on the drive,
motor or machinery.
Note: It is best practice to stop the drive before opening the main switch to the OFF
position, even though the switch is dimensioned to withstand the full load current of
the drive.
WARNING! The main switch (+F278 or +F316) does not isolate the input
cables and terminals from the input power supply. Before removing the front
cover and working on the drive, isolate the input cables from the main supply at the
distribution board or by opening the disconnector of the supply transformer.
WARNING! The maximum number of drive power-ups is five in ten minutes.
Too frequent power-ups can damage the charging circuit of the DC capacitors.
