Note
Some changes to the settings of the DIP-switches require
a discharge of the storage capacitor (section 7.1) to become
effective.

Closing support for -MU
If the DIP-switch is in ON position, the VM1 with activated
undervoltage release -MU can be closed even if no voltage
is applied to -MU.
For VM1: OFF
Always ON (enables -MO2 in spite of failure
of the microprocessor)
