Safety information

Risk of electric shock. Dangerous voltages are still present for up to 5 minutes after the
power supply has been switched off. The protective cover must not be opened until this
time has elapsed.
When opening the protective cover for the DC link, you must activate the release.
A suitable tool (e.g. screwdriver) must be used for this purpose.
The components must only be operated when the protective cover of the DC link is closed.
Damaged components must not be used further, as this could result in secondary damage
or accidents.
The DC link discharge time warning in the local language must be attached to all of the
components.
A set of labels in 16 languages is supplied with the component.
A sufficiently high supply short circuit power is required for tripping the fuses within the
predefined time in the event of a ground fault. The ratio between the line short-circuit power
and the rated power of the Line Module must be ≥ 30. Low system fault values increase the
time to trip beyond permissible levels (e.g. fire possible).
A ventilation clearance of 80 mm above and below the components must be observed.
The Basic Line Modules conduct a high leakage current via the PE conductor. A permanent
PE connection for the Basic Line Module or control cabinet is required due to the high
leakage current of the Basic Line Modules.
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.
