Important notes
Lethal electric shock by live parts with more
than 50 V!
WARNING
Exclusively operate the device
●
with plugged on connectors (even if there haven't been any lines con‐
nected to the connectors) and
●
with connected equipment grounding conductor!
Notes on installation
●
The cable is connected to the connection point using ring cable lugs.
●
Measure the necessary cross section of the connection cables accord‐
ing to the determined phase current I
LN
and the mains fuse.
