Electrical installation
4.6 AC mains connection (power supply)
The mains connection cable is always to be laid shielded. The shield connection at the
device is made using the shield lug on the connector X8 (Line IN).
For interference suppression on the ServoOne CM system, an optimised filter from KEBA
is to be fitted to the connection X8 (Line IN) on the supply unit. The supply current and
the total motor cable length must be taken into account for sizing the filter. You will find
details in chapter "A.6 Mains filter".
Use a shielded cable to connect the mains filter to the supply unit. Connect shield at
both ends, see figure (length L ≤ 1.5 m).

Connection example, mains supply
At the device end, the connection is made to the shield lug on the connector X8
(Line IN). Good shielding of the connection on the mains filter can be achieved by
