12.2.2 Power supply requirements

WARNING: Dangerous contact voltage

Only use power supply units that ensure safe isolation between the primary and

secondary circuits according to EN 50178.

For additional power supply requirements, please refer to the documentation for

your bus coupler and the power terminals.

Inline: Supply voltage requirements that differ from the system specifications

The specifications for Inline system supply voltages are described in “Technical data for

Inline” on page 154. However, some terminals have specific requirements. Therefore, al-

ways refer to the corresponding data sheet.

This section provides information about the various possible requirements within an In-

line system.

If you are using Inline in a system with other product ranges, also observe the tech-

nical data for these product ranges. Please refer to the corresponding documenta-

tion for this technical data.

Two options are available when using terminals, which have special requirements regard-

ing the power supply:

1 Observe the specific parameters for the power supply in the entire system.

2 Observe the specific parameters in the main circuit where the terminals are located.
