Installation and Connection
19 General Installation Instructions
For electric installation the local regulations in the respective countries (in Germany e. g.
VDE 0100) must be referred to.
WARNING
Separate protection
The NFP power supply must be separately protected by a 6 A slow-blow fuse and has to be
isolated from other facility parts (separate turn-off, e. g. by using an automatic cut-out with
>B< characteristics).
Before feeding the rated voltage the transmitter and sensor installation must be correctly
completed. The installation should be carried out by qualified personnel only.
Further statutory standards, regulations and technical rulings have to be taken into account.
All outer circuits, wires and lines connected to the device must have a minimum isolation re-
sistance of 250 kOhm. If the voltage exceeds 42 V DC an isolation resistance with 500 kOhm
min. will be required.
The cross-sectional dimension of the power supply wires must be 0.75 mm
2
(0.03 in
2
) and
must be in accordance to IEC 227 or IEC 245. The device protection rating is IP65. The max-
imum allowed switching voltage on the relay contacts must not exceed 250 V. According to
Ex protection it must be checked if the devices power supplies must be integrated into the fa-
cility’s emergency shutdown conception.
