Connection examples
NOTE
The current measurement input I4 of the basic
device with module:
· is only approved for a current measurement
using the current transformer.
· is designed for the connection of current
transformers with secondary currents of ../1 A
and ../5 A.
· has the current transformer ratio set to 5/5 A
by default.
· does not measure DC currents.
Because of the missing multiplier with a voltage,
only an apparent current measurement is

· has the current transformer ratio set to 5/5 A
by default.
· does not measure DC currents.
Because of the missing multiplier with a voltage,
only an apparent current measurement is
performed during the current measurement input
I4. Therefore, no power measurement is possible
through this input. No connection diagram can be
confi gured for the current measurement input.

Connection examples
NOTE
The current measurement input I4 of the basic
device with module:
· is only approved for a current measurement
using the current transformer.
· is designed for the connection of current
transformers with secondary currents of ../1 A
and ../5 A.
· has the current transformer ratio set to 5/5 A
by default.
· does not measure DC currents.
Because of the missing multiplier with a voltage,
only an apparent current measurement is
performed during the current measurement input
I4. Therefore, no power measurement is possible
through this input. No connection diagram can be
confi gured for the current measurement input.

Temperature sensor
• In the Measurement window, select the entry
Temperature sensor and press key 6 Enter.
• Select a suitable temperature sensor from
the list:
- PT100 (standard setting)
- PT1000

- KTY84
• Confi rm using key 6 Enter.
NOTE
With respect to all module-related settings,
also observe
· the specifi cations in the user manual relating
to the module, in particular the warning and
safety instructions.
· Step 10 “Connection examples”.
The user manuals for modules and basic devices
are available for download (www.janitza.de).
All module-related settings can also be easily
confi gured in the GridVis
®
software.
ATTENTION
Damage to the basic device, the module and/or
your system due to short circuit!
Too little insulation of the operating resource (such
as temperature sensor) at the analog inputs with
respect to the power circuits can cause damage to
your basic device, module and/or system.
· Ensure a reinforced or double insulation
of your operating resources with respect
to the power circuits!
· Use shielded lines to connect the temperature
sensor!

Connection example 1 - Residual current monitoring Connection example 2 - Residual current monitoring
NOTE
For the residual current monitoring, the basic de-
vice with module requires the mains frequency. For
this purpose, apply a measured voltage or confi g-
ure a fi xed frequency.
The residual current monitoring monitors the
residual currents via external current transformers
and, if a threshold value is exceeded, can trigger a
warning signal.
The basic device with module is not an indepen-
dent protection device against electric shock!
Recommendation: To confi gure the basic device
with module, use the GridVis

1) Power is determined from inputs I5 and I6 (U6) during the DC
power measurement. A voltage (U6) is converted into a current
signal by an active current transformer. The current signal
responds proportionately to the value of the input voltage.
2) For the setting of the transformer type 0 .. 20 mA at CH2, confi gure
a primary voltage for the measurement transformer ration and a
proportionate secondary current.
ATTENTION
During the start-up process, the basic device does not
recognize the module!
If there is no communication to the module, the module
functions are not supported (such as residual current or DC
power).
· Disconnect your system (the basic device) from
the power supply and check the position of the RCM
module. If necessary, apply slight pressure to press the
module onto the basic device until it audibly snaps in.
· If necessary, restart the basic device.
