4.2.1.2 Isolation
The controllers have an electrical insulation (isolating distance) between the power terminals and
the control terminals as well as to the housing:
Terminals X1 and X5 have a double basic insulation (double isolating distance, safe electrical
isolation to VDE0160, EN50178). The protection against contact is ensured without any
further measures.
The control inputs and outputs of all controllers are electrically isolated.
Danger!
Terminals X3, X4, X6, X7, X8, X9, X10 have a single basic insulation (single isolating
distance).
Protection against contact in the event of fault is ensured only by additional measures.
If an external voltage supply (24V DC) is used, the insulation level of a controller depends on
the insulation level of the voltage source.

4.2.1.3 Replacement of defective fuses
Replace defective fuses with the prescribed type only when no voltage is applied. (^ 3-7)
For single drives, the controller carries a hazardous voltage up to three minutes after mains
disconnection.
In a DC-bus connection, all controllers must be inhibited and separated from the mains.
4.2.1.4 Mains disconnection
Make a safety disconnection between the controller and the mains only via a contactor at the input
side.
Please observe that all drives connected to the DC bus must be inhibited.
