DANGER!
Danger to life due to electrical current!
Energized parts are dangerous to life.
Therefore:
m The device, the mounting range and the parts, which are to be mounted (for exam-
ple supply cables) must be off circuit during complete mounting
m The cross-section of the grounding conductor must be greater than 10 mm

NOTE!
Installation notes:
m Don’t connect mains filters in parallel.
m Don’t connect mains filters of the same type in series - the attenuation character-
istics will not be approved.
m Connect the PE-terminal on the load-side of the filter with low impedance to the
mounting board. Ideal is a zinc plated L-bracket or with a HF-earth strap.
m Suppress each drive individually from interferences. In case you have to suppress
all of the drives from interferences together, do not interrupt any of the screens be-
tween converter and the mains filter. This means the screened lines are not inter-
rupted by fuses, contactors or others, except with eventual necessary power
chokes.
