Grounding; Fibre Optic Cables - ABB ACS800-U4 Hardware Manual

Grounding

These instructions are intended for all who are responsible for the grounding of the
drive. Incorrect grounding can cause physical injury, death or equipment malfunction
and increase electromagnetic interference.
•
Ground the drive, the motor and adjoining equipment to ensure personnel
safety in all circumstances, and to reduce electromagnetic emission and pick-
up.
•
Make sure that grounding conductors are adequately sized as required by
safety regulations.
•
In a multiple-drive installation, connect each drive separately to protective
earth (PE).
•
ACS800-01: In European CE compliant installations and in other installations
where EMC emissions must be minimized, make a 360° high frequency
grounding of cable entries in order to suppress electromagnetic disturbances.
In addition, connect the cable shields to protective earth (PE) in order to meet
safety regulations.
(ACS800-02: 360° high frequency grounding of cable entries is not required.)
•
Do not install a drive with EMC filter option +E202 or +E200 (available for
ACS800-01 only) on 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 drive is higher than 3.5 mA AC or 10 mA
DC (stated by EN 50178, 5.2.11.1), a fixed protective earth connection is
required.

Fibre optic cables

WARNING! Handle the fibre optic cables with care. When unplugging optic cables,
always grab the connector, not the cable itself. Do not touch the ends of the fibres
with bare hands as the fibre is extremely sensitive to dirt. The maximum allowed
bend radius is 25 mm (1 in.).
