Motor housing and braking resistor can attain very high
operating temperatures! Danger of injury!
Prior to any work on the machine (e.g. exchange of tools),
disconnect the machine and secure against unintended
restart!
Safely secure movement range of machine during operation!
Danger of injury!

The connections on the control terminal strip and the encoder
inputs show a safe seperation in accordance with VDE 0100.
The person who sets up the systems or machines must
ensure that the existing or newly wired circuit meets the VDE
requirements for safe seperation.
A trouble-free and safe operation of the servo system is only warranted when the
following connection instructions are observed.
When deviated from, malfunctions and damages may occur in isolated cases.
– The servo controller KEB COMBIVERT S4 is only designed for a fixed connection.
– Do not interchange power cable and motor line.
– Lay control and power lines separately (min. 10 cm distance).
– Connect control lines only to switching elements and setting devices (relay,
switch, potentiometer), that are suitable for extra-low voltages.
– Use shielded/twisted control lines. Connect the shield only single-sided to PE of
the servo controller.
– Use shielded motor cables. Connect shield to the Servo controller to PE and
extensively connect to motor housing.
– Earth servo controller very well: star-shaped earthing, avoid earth loops,
shortest connection to main earthing terminal.
