Power loss
The manufacturer (switchgear manufacturer) of the system is responsible for
calculating the power loss. The calculation must take into account the fact that
the ventilation switches off in the event of a fire. It continues to run in normal
operation.
Please note the power loss information below when installing devices in
empty enclosures.
