Grounding - ABB ACS800 Series Hardware Manual

•
Fastening the cabinet by riveting or welding is not recommended. However, if
welding is necessary, ensure the return wire is properly connected in order not
to damage the electronic equipment in the cabinet. Also ensure that welding
fumes are not inhaled.
•
Ensure sufficient cooling of the unit.
WARNING! Ignoring the following instructions can cause damage to the equipment.
•
The printed circuit boards contain components sensitive to electrostatic
discharge. Wear a grounding wrist band when handling the boards. Do not
touch the boards unnecessarily.

Grounding

These instructions are for all personnel who are responsible for the grounding of the
converter.
WARNING! Ignoring the following instructions can cause physical injury or death,
or damage to the equipment.
•
Ground the converter, the generator and adjoining equipment to ensure
personnel safety in all circumstances, and to reduce electromagnetic emission
and pick-up.
•
Make sure that the conductivity of the grounding conductors is sufficient. Obey
the local regulations.
•
In a multiple-converter installation, connect each converter separately to
protective earth (PE).
•
Do not install a converter equipped with an EMC (line) filter to an ungrounded
power system or a high resistance-grounded (over 30 ohms) power system.
Note:
•
Power cable shields are suitable for equipment grounding conductors only
when adequately sized to meet safety regulations.
•
As the normal leakage current of the converter is higher than 3.5 mA AC or
10 mA DC, a fixed protective earth connection is required by EN 61800-5-1,
4.3.5.5.2. The cross-section of the protective grounding conductor must be at
least 10 mm
2 2
Cu or 16 mm Al.
