Manual Integrator Supercal 531 06-06-2011 11
Furthermore, attention has to be paid that the integrator is electrically compatible with the tempera-
ture sensors:
Pt100-temperature sensors must not be connected to an integrator which is designed for Pt500-
temperature sensors (and vice versa).
To avoid unauthorized access, the installations points have to be sealed after installation.
2.4.3.2 Interfering factors
If there is a risk of electric or electro-magnetic interferences, temperature sensors in 2- and 4-wire
technology with shielded cables or shielded cables on the connection heads have to be used. The
shields always have to be connected to the electric mass provided in the integrator.
The risk of interfering influences rises with the length of the sensor cable.
2.4.3.3 Security advice
Risk of accident in case of improper dismounting of directly immersed temperature sensors!
Mounting and dismounting may only be carried out by authorized personnel.
2.5 Installation guidelines
The installation and start-up of a heat meter may only be carried out by authorized personnel and
in accordance with the current standards, the local security and installation instructions.
The installation guidelines acc. to EN 1434-2 and EN 1434-6 have to be followed strictly. Please
note that the heat meter will only provide the requested precision and reliability if the local regula-
tions for electric installations and the guidelines given by the manufacturer are followed.
