Regulations
■
Connect the power supply and implement all safety
measures (e.g. RCD circuit) in accordance with
IEC 60364-4-41, the connection requirements of
your local power supply utility, and VDE or national
regulations.
■
Disconnect the system by means of a device that
simultaneously separates all non-earthed conductors
with at least 3 mm contact separation.
In addition, we recommend installing an AC/DC-sen-
sitive RCD (RCD class B ) for DC (fault) cur-
rents that can occur with energy efficient equipment.
Danger
Incorrect core assignment can result in serious
injury and damage to the appliance.
Never interchange cores "L" and "N".
