Line connection
4.6 Wideband Line Filter for Active Line Modules
The line filters listed conduct a high leakage current via the protective ground conductor. A
permanent PE connection for the line filter or control cabinet is required due to the high
leakage current of the line filters.
Furthermore, the following measures must be taken according to EN 61800-5-1:
Either protective ground conductor cross-sections ≥ 10 mm
protective ground conductor of the same cross-section as the first one.
Risk of electric shock. Dangerous voltages are still present for up to 5 minutes after the
power supply has been switched off.
Note
If a high-voltage test is conducted with alternating voltage in the system, the existing line
filters must be disconnected in order to obtain accurate measurements.
CAUTION
Only the line filters described in this Manual must be used. Other line filters can lead to line
harmonics that can interfere with or damage other loads powered from the line supply.
NOTICE
The air intake for the external heatsinks may not be drawn from heavily polluted
machining/processing areas. The reason for this is that substances, for example, cooling
and lubricating medium, can destroy the fan.
