and thus voids the warranty for any possible re-
sulting damage. Note in this regard Sect. “3.3
Intended use” on p. 13.
2.7 Safety information for handling current
transformers
The field of transformer technology groups the
totality of all devices that perform the function of a
current, voltage or measuring transformer together
as sensors.
The usage information for our devices, modules and
components contains the terms current transform-
er, voltage transformer or transformer, which are
representative for sensors.
A further distinction is made by the terms CT (cur-
rent transformer) and LP-CT (low-power current
transformer):
The term "current transformer" is used for special
transformers for the primary-proportional conversion
of currents of large magnitudes to directly measur-
able, smaller current values.
In contrast, the term "LP current transformer"
(low-power current transformer) is used for special
transformers for the primary-proportional conversion
of currents of large magnitudes to directly measur-
able, smaller voltage values (low power).
Current transformers and LP current transformers
provide safe galvanic isolation between the primary
circuit and the measurement circuit due to their de-
sign and their physical operating principle. For Janit-
za measurement devices, modules and components,
use only "transformers for measuring purposes"
that are suitable for the energy monitoring of your
system! Observe the corresponding warning notices!
Basic devices use only the term "current trans-
former" in the display for the configuration of both
current transformers and LP current transform-
ers.

800-CONModules
WARNING
Risk of injury or damage to the meter due to high
measured currents/measured voltages 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)!
· Only use current transformers with basic insu-
lation to IEC61010-1:2010!
· 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!
· Ground connections present on the secondary
windings of the current transformers must be
connected to ground!
· 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 measurement in-
puts of the modules with respect to the supply circuits
of the basic device can cause dangerous voltages
at the measurement input or damage to your device
(module)/system.
· Ensure reinforced or double insulation with
respect tothe supply circuits!

Please note before installing the module:
The scope of delivery of the 800-CON transfer
modules (set of 2) includes an input and an out-
put bus connector, so that each transfer module
can be used with the corresponding bus connec-
tor at the output or input of a series of measure-
ment devices and modules.

4.3 Connection of device and module series with
the 800-CON transfer modules (set of 2)
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
If the basic device does not recognize the module(s)
during the power-up procedure, the module functions
are not supported. If there is no communication be-
tween the basic device and the modules, proceed
as follows:
· 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,
