Control cabinet installation
Installation
For high frequency interference currents, the housing of the ADI4 module must be connected
with low-resistance to the back wall of the control cabinet, and this wall in turn must be
connected with low-resistance to the motors/machines. The module should be installed on a
bare mounting wall. The connection between the mounting wall and the motors/machines
must be electrically conductive and have a large surface area. Coated cabinet walls and DIN
rails, or similar mounting means with a small contact area, do not meet this requirement.
Cable routing
Power and signal cables must always be routed separately. All I/O interface (X6-1/X6-2)
signal lines should exit jointly. Single strands that are related from the signal point of view
must be twisted together. Signal cables and encoder cables should be installed separately.
All cables and lines within the control cabinet should always be placed as close as possible
to the control cabinet walls. Extended installation through open space can cause interference
injections (antenna effect). The proximity to sources of interference (contactors,
transformers, etc.) must be avoided by placing a shield plate between the cable and the
source of interference, if necessary. Cables and conductors should not be extended using
terminals or similar devices. To protect against interference injections from external sources,
signal cables must be shielded.
The module has been designed for operation in an enclosed control cabinet. Operation
outside an enclosed control cabinet is not permissible.
