Wideband line
Wideband line filters function in the frequency range from 2 kHz to 30 MHz.
filter
Load frequency harmonics are effectively limited using a wideband line filter.
They are required when sensitive loads, such as electronic power supplies, etc.,
are operated on the same line supply. This can prevent impairment, damage,
and premature aging of these loads.
Basic line filter
Basic line filters function in the frequency range from 150 kHz to 30 MHz. This
especially suppresses disturbances for radio–based services.
Safety information
Caution
!
The line filters are only suitable for the direct connection to TN systems.
The line filters listed conduct a high leakage current over the PE conductor. A
permanent PE connection for the line filter or control cabinet is required due to
the high leakage current of the line filters.
Only the line filters described in this Configuration Manual should be used.
Other line filters can cause line harmonics that can interfere with or damage
other loads powered from the line supply.
It is not permissible to connect other loads after the line filter.
Measures according to DIN EN 61800–5–1 must be taken, e.g. a PE conductor
10 mm
the same cross–section as the original PE conductor.
Danger
!
The 100 mm clearances above and below the components must be observed.
The mounting position must ensure that cool air flows vertically through the
filter. This prevents thermal overloading of the filter.
A hazardous voltage will be present at the terminals for up to 30 minutes after
the system has been shutdown depending on the DC link capacitance.
For this reason, opening the device or removing the cover is permitted only
after 30 minutes have elapsed since the device was switched to the
voltage–free state. All covers must be reattached before the line voltage is
switched on.
Danger of death!
Touching live terminals, cables or device parts can result in serious injury or
death!
Note
If the system is subject to a high–voltage test using AC voltage, any existing
line filter must be disconnected in order to obtain a correct measurement result.
