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 2.5 mm

wire between the operator panel’s quick-connect plinth

and the panel’s chassis, see 2 in drawing above.

Connect a 6 mm

or 4 mm

wire or grounding braid between the operator

panel’s chassis and the closest groun ding point on the door, see 3 in 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. Minimum

cross-section of the cable

is 2.5 mm

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.
