11. Installation
To ensure, the EMC protection requirements are fulfilled, the connecting cable has to be
shielded.
The shield of the mounted cable of the HBLS is el. connected to the connector housing.
The user has to fit a metal flange connector and its case has to be grounded.
All extending lines (serial communication interface, counter modules, enabling switches, E-
Stop) have also to be shielded and grounded at a central grounding point at the control.
Suitable RS 422-receiver circuits are necessary for the transmission of the handwheel
signals A; /A and B; /B (e.g. 75176).
It is not permitted to use TTL level signals (only A and B, without /A or /B).
The serial communication interface requires an RS 422A transmitter circuit and an RS 422A
receiver circuit.
For the correct choice of the wire diameters, the whole cable length is to be calculated.
