4 Connection and installation
4.1 General notes on installation
Strictly follow the safety regulations when installing!
Type of protection IP20
Route all signal lines for the interfacing of digital inputs and contact monitoring separately.
In any case isolate 230 VAC voltages from low voltage lines, if these voltages are used in
connection with the application.
The cable lengths for digital inputs and outputs must not exceed
30 m.
Measures concerning the electromagnetic compatibility (EMC)
The KSM module is intended for use in the drive environment and meets the
EMC-requirements mentioned above.
It is also assumed that the electromagnetic compatibility of the overall system is ensured by
application of appropriate measures.
Safety note:
Electric power supply lines of the KSM and “discontinuous-action lines” of the power
converter must be isolated from each other.
Signal lines and power lines of the power converter must be routed through separate cable
ducts. The distance between the cable ducts should be minimum 10 mm.
Only shielded cables must be used to connect the position and speed sensors. The signal
transmission cable must be RS-485-standard compliant (lines twisted in pairs).
Care must be taken to ensure that the shielding is correctly connected in the 9-pin
SUB-D plugs of the position and speed sensors. Only metal or metal coated plugs are
permitted.
The shielding on the sensor side must comply with appropriate methods.
EMC-compliant installation of the power converter technology in the environment of the
KSM module must be assured. Special attention must be paid to the routing of cables, the
shielding of motor cables and the connection of the braking resistor. Strict compliance with
the installation instructions of the power converter manufacturer is mandatory.
All contactors in the environment of the power converter must be equipped with appropriate
suppressor circuits.
Suitable measures to protect against overvoltages must be applied.
