Safety instructions 15

Grounding

These instructions are intended for all who are responsible for the grounding of the

drive.

WARNING! Ignoring the following instructions can cause physical injury,

death, increased electromagnetic interference and equipment malfunction:

• Ground the drive, motor and adjoining equipment to ensure personnel safety

in all circumstances, and to reduce electromagnetic emission and

interference.

• 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).

• 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.

• Do not install d drive with EMC filter options +E200 or +E202 on an

ungrounded power system or a high-resistance-grounded (over 30 ohms)

power system. See page 89.

Note:

• Power cable shields are suitable for equipment grounding conductors only

when adequately sized to meet safety regulations.

• Standard EN 61800-5-1 (section 4.3.5.5.2.) requires that as the normal touch

current of the drive is higher than 3.5 mA AC or 10 mA DC, you must use a

fixed protective earth connection and

• a cross-section of the protective earthing conductor of at least 10 mm

or 16 mm

Al,

• automatic disconnection of the supply in case of discontinuity of the

protective earthing conductor,

• a second protective earthing conductor of the same cross-sectional area

as the original protective earthing conductor.
