3 Safety notices
3.1 Symbols used
Important information
Non-observance can lead to malfunction.
General warning
Non-observance can lead to damage or malfunction.
Warning of dangerous electric voltage
Non-observance can lead to physical injury!
3.2 Intended use
The device is used as an energy calculator for heating, cooling and air conditioning applications in
district heating or cooling, in building management services and in industrial energy metering.
It is part of a combined heating/cooling or air conditioning meter, consisting of a calculator, a pair of
temperature sensors and a flow meter, or as a transducer for a flow meter.
The environmental conditions described in the technical specifications, as well as the installation and
operating instructions must be complied with.
3.3 Inappropriate use
The device must not be used:
•In explosion-risk zones (no ex-risk protection!)
•In a wet environment (condensing, splashing or dripping water)
•Outdoors, without suitable protection
•In environmental conditions (temperature, humidity, vibrations, electromagnetic in-
terference etc.) that do not comply with the technical specifications
•In all other instances that do not conform to its intended use
The device can be dangerous if it is not used as intended, or not in accordance with the installation
and operating instructions. In order to avoid this, it is essential that the safety instructions, operating
conditions (see technical specifications) and the relevant chapters of these instructions are strictly
adhered to.
The manufacturer accepts no liability for damage arising from inappropriate use.

3.4 Installation guidelines
The installation should be performed by authorised, skilled personnel, in compliance with
the regulations in force (EN1434 part 6 Regulations and recommendations for installation
and operation) and the recommendations of the industry-specific associations (e.g. the
AGFW series of leaflets on district heating supplies).
The skilled personnel must have read and understood these instructions. The require-
ments in the instructions and the applicable regulations on electrical installations must al-
ways be observed.
Work on electrical circuits with hazardous voltages (> 24 VAC or >42 VDC) may only be
carried out by authorised, skilled people, in compliance with the locally applicable regula-
tions!

Wiring diagram
The wiring diagram is on the
inside of the housing cover.
Connecting to mains power supply 100 - 240 VAC
The mains supply must be connected via a two-pole separator and be adequately protected
against unauthorised interruption.
The mains supply 100 - 240 VAC
may only be connected to the fol-
lowing terminals:
Terminals L, N (supply module)
Terminals 110, 115 (relay module 2x240
VAC)
The device must be protected by a 10 AT external fuse.
The device is fully isolated and requires no grounding connections.
Connection to other terminals is extremely dangerous and can permanently dam-
age the instrument!
Connecting to low voltage supply 24 VDC
