Description
Total power rating (setting per channel) •
Maximum permitted deviation from
total power (setting per channel)
Note
Scaling the total power for parallel connection of loads
• For a connection of the load between phase and neutral conductor, the power ratings to
be configured must be scaled to 230 V.
• For a connection of the load between phase and phase, the power ratings to be
configured must be scaled to 400 V.
