2.3 Safety during the individual operating phases
Following safety instructions must be observed during the assembly of the device.
Danger due to electric shock!
All utilised power supplies must be switched off prior to the work. The
electric cables must be installed according to the respective country
regulations (German VDE 0100). The measuring cables must be installed
separately from the power cord. The connection between the protective
ground conductor connection (in the respective device carrier) and a
protective ground conductor must be established.
Danger due to electric shock!
Due to any disconnection of the protective ground conductor in the device
carrier the device can become dangerous. Intended disconnections are not
permitted. The device must be shut down and secured against unintended
use in case it is assumed that a safe operation is no more possible.
Danger due to electric shock!
Do not open live devices! Active parts can be exposed during opening
devices or removing covers. Connection points can be active as well!
Attention!
The device shall never be operated despite visible defects.
Attention!
Observe the applicable accident prevention regulations for your system,
such as e.g. the German Statutory Accident Insurance Association
(DGUV) regulation 3 "electrical systems and operating materials" during
assembly, commissioning, maintenance and removal of defects.
Attention!
Clean contaminated contacts with oil-free compressed air or spirit and a
lint-free cloth.
Material damages due to electrostatic loading!
Observe the safety measures according to DIN EN 61340-51/-3 to prevent
an electrostatic loading!
Electrical connection!
The electric cables must be installed according to the respective country
regulations (in Germany VDE 0100). The measuring cables must be
installed separately from the power cord. The connection between the
protective ground conductor connection (in the respective device carrier)
and a protective ground conductor must be established.
Explosion protection!
It is permitted to use the device in explosion zone 22 and 2 with closed
lid. It is mandatory to ensure that no explosive ambient conditions, such
as e.g. development of dust, exist prior to opening the device for e.g.
parametrisation.
