6. Initial Start-Up
6.1. Electrical connection
The electrical connection may only be carried out by authorised personnel in a de-energised condition.
Signal outputs must not be used in safety circuits.
As far as the electrical safety is concerned, the protection against unintentional contact of the con-
nected and therefore electrically interconnected apparatus and the insulation of the feed cables must
be designed for the highest voltage, which can occur in the device.
To avoid EMC disturbances, the physical ambient and operational conditions at the place where the
product is installed, must meet the provisions laid down in the paragraph “Electromagnetic Compatibility
(EMC)” of DIN EN 60204-1.
