Additional Installation Tips

6 AdditionalInstallationTips

When experiencing communication problems in for example noisy environments

or when operating close to temperature limits, the following recommendations

are to be noticed.

6.1 GroundingtheOperatorPanel

5350

Door

Operator panel

Ferrite core

Mounting plate in the cabinet

Power supply

24 V DC

The operator panel’s mounting clamps do not provide a secure grounding

connection between the panel and the device cabinet, see 1 in drawing above.

Connect a wire that is sized correctly according to local electrical codes

between the operator panel’s quick-connect plinth and the panel’s chassis, see

2indrawingabove.

Connect a wire or grounding braid that is sized correctly according to local

electrical codes between the operator panel’s chassis and the closest grounding

point on the door, see 3 i n drawing above.

Connect a strong but short grounding braid between the door and the device

cabinet,see 4 in drawing above.

Twist the cables onto the 24

V DC feed, see 5 in drawing above.

2 turns around the ferrite core provide 4 times the suppression of 1 turn.

3 turns around the ferrite

core provide 9 times the suppression of 1 turn.

A ferrite core suppresses disturbances to the 24 V feed, see 6 in drawing above.
