Electrical isolation

5.1.2 Electrical isolation
The control connections (X2) are double−insulated (safe electrical isolation to
EN 61800−5−1). The protection against accidental contact is ensured without any further
measures.
If an external voltage supply (24V DC) is used, the insulation level of the regenerative
power supply depends on the insulation level of the voltage source.
