CAUTION!
Electromagnetic fields!
Disturbances or failure of the system possible!
The rules described below must be observed for installation, in
order to rule out the consequences of excessive disturbance effects
as far as possible.
 In correlation with electronic controls, no inductive loads must be
switched without suitable interference elimination.
 For DC operation, suitable interference elimination can be
achieved by arranging recovery diodes. For AC operation,
commercially available erasing elements matching the
connector type can be used.
 Only the interference elimination element mounted immediately
at the point of inductivity serves its purpose. Otherwise, the
switching pulse may even emit increased interference via the
interference elimination elements. It is much easier to avoid
sources of interference in the first place, than to eliminate the
effects of existing interference.
 In no case must the contacts switching unerased inductive loads
be arranged in the same room as the PacDrive™ components.
The same goes for cables carrying unerased, switched
inductivity and cables running parallel to them. The controller
must be separated from such "disturbers" by a Faraday cage
(own section in the switching cabinet).
5.7 Commissioning
We urgently recommend that you use ELAU staff for
commissioning.
You should do so not only for warranty reasons. At the same time
 the equipment is checked,
 the optimum configuration is determined,
 and the operating staff are instructed.
DANGER!
High leakage current!
Life hazard!
 The leakage current is greater than 3.5 mA. Therefore the units
must have a firm connection to the power grid (according to DIN
EN 50178 - equipment of high-voltage systems).
