Table 34: Information on the power supply for the actuators
Attention:
The reverse polarity protection only works if the supply
of the actuators is protected with an overcurrent fuse (10 A, mT) and
switched off upon short-circuit within 10 to 100 ms at the latest.
Warning:
In case of polarity reversal, a power supply unit with current
regulation or an incorrect fuse will lead to destruction of the module.
