❏ 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 common 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.
