Installation notes
CAUTION!
The electrical connection must only be made by qualified personnel.
The choice of cable, the installation and the electrical connection must conform to the requirements of
VDE 0100 „Regulations for the installation of power circuits with nominal voltages below 1000 V", or the
appropriate local regulations..
If contact with live parts is possible while working on the unit, it must be completely disconnected from
the supply.
Earth the instrument at the PE terminal to the protective conductor. This cable must have a cross-section
that is at least as large as the supply cables. Earth cables must be run in a star configuration to a com-
mon earth point which is connected to the protective earth of the supply. Do not loop earth cables, i.e.
do not run them from one instrument to another.
Apart from faulty installation, incorrect settings on the thermostat can affect the proper functioning of the
following process or lead to damage. Setting up must therefore be restricted to qualified personnel.
Please observe the appropriate safety regulations in this respect.
