WARNING
Risk of injury due to high currents and high electri-
cal voltages!
Severe bodily injury or death can result from:
·Touching bare or stripped leads that are ener-
gized.
·Inputs of devices, components and modules are
dangerous to touch.
Therefore, please note for your system:
·
Disconnect the supply of power before starting
work!
·
Secure it against being switched on!
·
Check to be sure it is de-energized!
·
Ground and short circuit! Use the ground connec-
tion points with the ground symbol for grounding!
·
Cover or block off adjacent live parts!
INFORMATION
·When setting up your meter and module topolo-
gy, bear in mind that the UMG 801 as the basic
device allows the mounting of
up to 10 modules
.
·Always mount components of your JanBus sys-
tem from the output bus connector to the input
bus connector (from left to right). This will avoid an
incorrect connection of remote JanBus systems!
·Use end brackets and shield clamps with strain
relief to set up your meter and module topology
on a suitable DIN rail (for DIN rail types, see Sect.
“8. Technical data” on p. 25).
·For recommended data cables, refer to Sect. “5.2
Data cable for connecting the 800-CON transfer
·When setting up your meter and module topology,
observe the maximum bus length of the JanBus
(see Sect. “8. Technical data” on p. 25).

5.1 Data transfer with 800-CON module
Your 800-CON transfer module (set of 2) in combina-
tion with a basic device (UMG 801) and, for exam-
ple, current measuring modules, serves to connect
remote measurement points.
With the transfer modules, you can implement
meter and module topologies (e.g. UMG 801 with
800-CT8-A current measuring modules) with flexible
arrangement of your DIN rails in the switchboard
cabinet or small distribution board (for DIN rail types,
see chapter „8. Technical data“ on page 25).
