Connecting the control leads
CAUTION
The boards contain electrostatically sensitive components. Failure to handle boards
correctly can easily cause irreparable damage to these components.
See also under the measures recommended to protect ESD-endangered components in
section 1.
When installed, control leads must be shielded and isolated from the power cables, laying them at a
minimum spacing of 20 cm. The shield must be connected at both ends. The shield is attached to the
housing by means of shielding clamps. The diagram below explains how to handle the shielding clamps.
If they intersect, control and power cables must be run at an angle of 90° to each other
Fitting the shielding clamp
Releasing the shielding clamp
manually or using a screwdriver, press the clamp together and extract it in the updown
direction.
Caution!
The clamps are sharp-edged!
