2.7 Safety information for handling current
transformers/current sensors
Definition of the terms current transformers/cur-
rent sensors:
In this user manual, the term "current transformer"
is used for special transformers for the proportional
conversion of currents of large amperages to directly
measurable, smaller current values.
In contrast, the term "current sensor" is used for
special transformers for the proportional conversion
of currents of large amperage to directly measurable,
smaller voltage values.
Current transformers and current sensors provide a
safe galvanic isolation between the primary circuit
and the measurement circuit due to their construc-
tive design and their physical operating principle.
WARNING
Risk of injury due to large currents and high elec-
trical voltage on the current transformers!
Current transformers operated while open on the
secondary side (high voltage peaks pose a hazard
when touched) can result in severe bodily injury or
death.
· Avoid operating the current transformers while
open; short circuit the unloaded transformers!
· Before interrupting the current supply, short
circuit the secondary connections of the cur-
rent transformers. Switch any test switches
that automatically short circuit the secondary
lines of the current transformers to the “Test”
status (Check the test switch/short circuiting
connection beforehand)!
· Only use current transformers/current sensors
with basic insulation according to IEC 61010-
1:2010!
· Caution, even current transformers rated as
safe for open operation can pose a hazard
when touched during operation while open!
· Make sure that screw terminals for the current
transformer connection on the device are ade-
quately tightened!
· Comply with the information and provisions in
the documentation of your current transform-
ers!

800-CONModules
CAUTION
Risk of injury or damage to the meter due to high
measurement currents at the connections of the
current transformers!
High measurement currents can cause temperatures
of up to 80°C (176°F) on the connections of the
current transformers
· Use wiring that is designed for an operating
temperature of at least 80°C (176°F)!
· The current transformers can be hot even after
the power supply has been switched off. Allow
the connections of the current transformers
and the connecting cables to cool down before
touching them!
CAUTION
Risk of injury or damage to the basic device (mod-
ule) and/or your system due to a short circuit!
Inadequate insulation at the current measuring inputs
of the modules with respect to the supply circuits of
the basic device can cause dangerous voltages at the

with the 800-CON transfer modules
To ensure trouble-free operation of your device
series with modules and thus your system, connect
your transfer modules via shield clamps. The shield
connection serves as protection against overvoltag-
es and electromagnetic interference. Also provide a
strain relief during installation that protects the data
cable from being torn out unintentionally. Connect
the transfer modules with the recommended data
cables. Please note the warnings and information
below!

INFORMATION
The basic device does not recognize modules during
the power-up procedure!
If there is no communication to modules, the module
functions are not supported (e.g. current measure-
ments).
· Disconnect your system from the power supply
and check the condition of the bus connectors
and the connections of your modules to the basic
device (JanBus interface). If necessary, push the
contacts of the module bus connectors into the
sockets of the basic device bus connector or the
attached modules so that the bus connectors
(devices) are coupled.
· For remote module series, check the connection
of the transfer modules with the connection via
the shield clamps.
· If necessary, restart the basic device.
· If these measures do not lead to the desired
result, please contact our Support – www.janitza.

ATTENTION
Incorrect installation of the data cable can destroy
your basic device with modules or your system!
A faulty or incorrectly installed data cable between
the transfer modules can lead to the destruction of
your basic device with modules and thus to material
damage.
· For the connection between the transfer modules,
use a stranded twisted pair, shielded data cable
with a 1:1 cable connection (see Sect. “5.2 Data
cable for connecting the 800-CON transfer
modules” on p. 23)!
· Always connect your transfer modules via
shield clamps with a strain relief!
· Protect your system against overvoltages and
electromagnetic interference by connecting the
data cable shield to the shield clamp!
· Always connect the data cable shield (ground)
within the same grounding potentials! With dif-
ferent ground potentials, connect the data cable
shield at least at one end!

INFORMATION
The transfer modules (800-CON) of the set of 2 are
suitable as output or input modules!
However, make sure to mount the correct bus con-
nectors (output and input)!
Always mount components of your JanBus system
from the output bus connector to the input bus
connector. This will avoid an incorrect connection of
remote JanBus systems! Cf. Sect. “5.1 Data transfer
with 800-CON module” on p. 22.
INFORMATION
The transfer modules are supplied with the neces-
sary screw terminals and bus connectors (JanBus
interface) for connection to the basic device or other
modules.
