Protecting the connection cables
To protect the connection cables at U
L1
, U
L2
and U
L3
, make sure there is adequate cable
protection, especially after cross-section transitions.
If short-circuit resistance according to IEC 61439-1:2009 is ensured by the design, there is
no need for separate cable protection for the AI Energy Meter 480VAC ST.
