4.2 Connections
4.2.1 Power supply
The product is powered through the X31 connection (Power in). Two supply cables can
be connected to the plug:
• Supply cable 1: 1L+ (U
1L
) and reference potential 1L−
• Supply cable 2: 2L+ (U
2L
) and reference potential 2L−
Both supply cables are electrically isolated from each other and functional ground.
Each pin of plug X31 (Power in) is connected to the same pin of socket X32 (Power out)
and makes it possible to pass the power on to the next device.
