Commissioning and functional check
Removing and inserting of preliminary fuses
The preliminary fuses must be re-inserted for commissioning and functional
check of the meter with communication unit CU-Bx. While the terminal
cover is not screwed on there is danger of contact with the connection ter-
minals. Contact with live parts is dangerous to life. The fuses should always
be removed to make any modifications to the installation and kept in a safe
place until work is completed to prevent other persons re-inserting them
unnoticed.
The installed meter with installation unit CU-Bx should be put into operation
and checked as follows:
1.
Connect a signal source to the interface to check the S0 interface. If
the meter is prepared for processing the signal, check after a time
whether the register(s) concerned has/have changed.
2.
Perform a data readout via the interface to check the RS485 or RS232
interface with a suitable unit (laptop, handheld terminal).
3.
Ensure that the units connected to the RS485 interface have different
addresses. These are the IEC unit address for IEC 61107 or the
physical unit address for dlms.
4.
Also ensure that all units connected have the same bit rate for the
RS485 interface.
