Safety in the individual operating phases
When installing the control unit and during operation, the following safety instructions must be
observed.
Danger of Electrocution!
Before working on the device, switch off all power supplies used. The
electrical cables must be laid according to the respective national
regulations (in Germany VDE 0100). The measuring cables must be laid
separately from the power lines. The connection between the connector
for the functional earth (in the respective equipment carrier) and a
protective earth must be established.
Danger of Electrocution!
Any interruption of the protective earth in the equipment carrier can result
in the device becoming a hazard. Intentional interruptions are not
permitted. If there is a suspicion that it is no longer possible to operate
the device safely, it must be shut off and secured against being
unintentionally switched on.
Danger of Electrocution!
Do not open the device when it is connected to the voltage! When
opening the devices or removing covers and parts, live parts may be
exposed. Connection points can also be live!
Attention!
The device must never be put into operation even if damage is
recognisable.
Attention!
During installation, commissioning, maintenance and troubleshooting,
observe accident prevention regulations for your system, e.g. DGUV
Regulation 3 "Electrical installations and equipment".
Attention!
Clean dirty contacts with oil-free compressed air or ethyl alcohol and a
lint-free cloth.
Warning of material damage caused by electrostatic charge!
Observe the safety measures according to BS EN 61340-51/-3 to avoid
electrostatic discharge!
Electrical connection!
The cable shielding belongs to the measurement earth.
The effects of interference fields can be prevented through use of twisted
and screened measuring lines.
