Reference symbols / Safety instructions
The following symbols are used in
conjunction with these important in-
structions concerning personal safety
and technical reliability.
“Safety instructions“ are
instructions with which you
must comply exactly, to
prevent injury and material
losses.
Danger through “live“ elec-
trical components.

ON/OFF switch before remo-
ving the casing.

ponents or contacts when the
