ty requirements and regulations in order to avoid accidents shall be observed.
The safety-related values of the connected iXT0 shall comply with the technical
specifications or the specifications contained in the according EC type examina-
tion certificate.
Interconnecting several active devices within an intrinsically safe circuit may result
in different safe maximum values. In such cases the intrinsic safety may be im-
paired!
All operations on the device which go beyond installation or connection measures
in principle shall be carried out by NIVUS staff or personnel authorised by NIVUS
due to reasons of safety and guarantee.
