2.8.1 Power supply
The installation of the mains power supply for connecting to our equipment must be
carried out in accordance with the international specifications and the regulations derived
from them. These essentially include the recommendations of at least one of the following
commissions:
− International Electrotechnical Commission (IEC)
− European Committee for Electrotechnical Standardization (CENELEC)
− Association of German Electrotechnicians (VDE)
Our units are built to VDE protection class
I and must be connected to a protective conductor.
Interference suppression measures
If the mains power supply is subject to electric interference, interference suppression
measures must be taken on site, e.g.:
− provision of separate mains cable to our equipment.
− in problem cases, insertion of capacitively decoupled isolating transformers or other
suppressors into the mains supply lines to our equipment.
