Only allow electricians to carry out the electrical connection.
The choice of cable, the installation and the electrical connection of the
device must conform to the requirements of VDE 0100 "Regulations on the
Installation of Power Circuits with Nominal Voltages below 1000 V" and/or
the appropriate local regulations.
If contact with live parts is possible while working on the device, it must be
completely isolated from the supply.
Earth the device at the PE terminal to the protective earth conductor.
Ensure that this line has at least a cross section identical to that of the sup-
ply lines. Earth/ground cables must be routed in a star configuration to a
common earthing point that is connected to the protective earth of the sup-
ply installation. Do not loop earth cables, i.e. do not run them from one
device to another.
In addition to a faulty installation, also incorrectly set values on the thermo-
stat could impair the orderly function of the following process or lead to
other damage. Restrict the setting to expert personnel. Please adhere to
the safety regulations for this case.
Terminals and connections are suitable for internal wires
The connection is suitable for stationary line
Line insertion without strain relief
The device corresponds to protection class I.
Capillary tube without protective earth function!
For the probe and the capillary line, the user is
responsible for the required protection against electrical shock.
