Safety pointers for the installation
Life threatening voltage inside the instrument:
Connecting electrical lines is extremely dangerous. Parts of the system can also be damaged.
Local regulations must be observed at all times for electrical installations.
Further, the following basic principles must be observed:
It is imperative that the protective conductor is connected.
Because the instrument has no main switch, a suitable disconnection device (switch,
plug) should be installed near the service voltage. It must be designated and easily ac-
cessible.
The instrument box must not be charged with voltage until the installation is complet-
ed and the front cover is mounted.
On instruments with an optional mains device, a back-up fuse with a max. tripping
current of 16 A must be present. The cables must be able to withstand this load.
If faults cannot be remedied, the unit must be put out of operation and protected
against inadvertent operation.
The installation and commissioning of the Modbus RTU and Profibus DP field bus interfaces
are described in the Reference Manual.
