5.5 Requirements on the electrical connection

WARNING: Material damage from incorrect fuses for the mains supply line

Dimension the mains fuse according to the currents specified in the technical data. In-

correct protection can result in operating errors or fire.

When connecting the conductors, please observe the following

• Only insert conductors, but not insulation, into the connection terminal blocks.

• Check that the screw connections of the connection terminal blocks are tight.

• Adapt the screw connections of the cable entries to the cable cross-section.

• Use flexible cables to simplify installation.

Input mains

• Connect the neutral conductor on the input side in any case.

The neutral conductor of the bypass always has to be connected to the neutral conduc-

tor of the mains input.
