NFP - rev. 04 / 23.05.2018

page 11

WARNING

Disconnect the systems from mains

Maintenance, cleaning and/or repairs (by qualified personnel only) may only be performed

when de-energised.

Disregarding may lead to electric shocks.

Putting into operation by trained experts only

The entire measurement system shall be installed and put into operation by trained expert

personnel only.

Integrated buffer battery

The exchange of the integrated buffer battery shall be carried out by NIVUS staff or per-

sonnel authorised by NIVUS only. Otherwise the guarantee expires.

Liability disclaimer

The manufacturer reserves the right to change the contents of this document including this li-

ability disclaimer without prior notice and cannot be held responsible in any way for possible

consequences resulting from such changes.

For connection, initial start-up and operation as well as maintenance of the unit the following

information and higher legal regulations of the respective country (in Germany e. g. VDE reg-

ulations) such as applicable Ex regulations as well as safety requirements and regulations in

order to avoid accidents shall be observed.

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 safe-

ty and guarantee.

Operate the transmitter only in technically perfect working order.

Improper Use

Not being operated in accordance with the requirements may impair the safety. The manufac-

turer is not responsible for failures resulting from improper use.

Use in accordance with the requirements

Note

The instrument is intended solely for the purpose described below.

Modifying or using the instruments for any other purposes without the manufacturer’s writ-

ten consent will not be considered as use in accordance with the requirements.

The manufacturer cannot be held responsible for any damage resulting from improper use.

The user alone bears any risk.

The permanent flow meter Type NFP - NIVUS Full Pipe including the accompanying sensors

is designed for continuous flow measurement of slight to heavily polluted media in permanent

full pipes.
