Connection and Assembly
NOTE
Housing ground/functional earth
30/51
To ensure contact protection and avoid electronic interference, the protective screen
must be refitted, and the terminal box door closed after installation of the lines for
mains supply.
As an additional protective measure, an earth connection has been attached
to the SL1200A to reduce and systematically dissipate
electromagnetic/electrical interference.
