Instructions in accordance with Directive 2014/34/EU TÜV 98 ATEX 1380 X
Isolating amplifier VP-… Edition: 08.2017
I Range of application
The isolating amplifiers VP-… are primarily used to supply electronic fill level sensors and forward the meas-
ured data to a superordinate evaluation system.
II Standards
The isolating amplifier is designed in accordance with the following European standards
EN 60079-0:2012 + A11:2013 Equipment - General Requirements
EN 60079-11:2012 Equipment protection by intrinsic safety "i"
III Instructions for safe …
III.a … use
The isolating amplifier serves as associated equipment and is not suitable for use in potentially explosive
area. The intrinsically safe sensor circuits may be routed into the Zone 0 or Zone 20 and are applicable for
all gas groups (IIA, IIB and IIC) as well as all dust groups (IIIA, IIIB and IIIC).
The approval applies to the device versions
VP-1 Isolating amplifier with eight intrinsically safe sensor circuits
VP-2 Isolating amplifier with two intrinsically safe sensor circuits
VP-4 Isolating amplifier with four intrinsically safe sensor circuits
III.b … assembling and dismantling
The isolating amplifier is manufactured with an open plastic housing for DIN rail mounting. The housing
must not be opened!
III.c … installation
The wiring must be carried out only with the power disconnected. Special rules and regulations, including
EN 60079-14 and local installation regulations, must be observed.
The isolating amplifier must be installed outside the potentially explosive area in a housing with degree of
protection of at least IP20. If the isolating amplifier is mounted outdoors, the housing protection class must
be at least IP54.
For the wiring (preferably blue cable) from the sensor to the isolating amplifier, the permissible inductance
and capacitance under item V must not be exceeded.
