The possible accuracy depends on the quality of the synchronization signal because the
synchronization uses the zero crossings of the signal.

3.4.1 Protection
1 2 3 N
~ ~ ~
The current outputs are protected against open-circuit and overload conditions. The current amplifier
is additionally protected against overtemperature.
NOTICE
Equipment damage possible.
Infeed of currents from external sources may damage the current outputs. Only in the non-operative
state, the current outputs are protected by short-circuit relays against external infeed.
