2.7 Safety information for handling current
transformers and devices with residual
current measurement
WARNING
Risk of injury due to large currents and high
electrical 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 trans-
formers!
·Before interrupting the current supply,
short circuit the secondary connections of
the current 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 with basic
insulation 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 cur-
rent transformer connection on the device
are adequately tightened!
·Comply with the information and provisions
in the documentation of your current trans-
formers!
CAUTION
Risk of injury or damage to the device due to
high measurement currents on the connections
of the current transformers!
High measurement currents can cause tempera-
tures 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

To be able to use the modules 96-PA-RCM and
96-PA-RCM-EL, the basic devices of the UMG96-
PA series require firmware from version 2.0 and
hardware from version 4.
The devices of the UMG96-PQ-L series already
have module capability in the standard version.
The hardware version of your basic device is
specified on the rating plate. For more detailed in-
formation on this, refer to the user manual ofyour
basic device.
You can check the installed firmware version in
the user interface of your basic device via:
Menu > Configuration > System > Version.
You can find the latest firmware as a download for
your corresponding basic device at www.janitza.
de.
Your Janitza partner or the support team are
happy to be of assistance to you with regard to
questions on updating the hardware version or
firmware installation.

CAUTION
Disregard of the installation instructions may
cause property damage or personal injury!
Non-observance of the assembly instructions may
cause damage to your basic device with module or
destroy it and/or may also result in personal injury.
·Observe the assembly instructions of your
basic device.
·Disconnect your basic device from the pow-
er supply prior mounting the module!
·Provide adequate air circulation in your
installation environment and cooling, as
needed, when the ambient temperatures are
high.
·Before mounting, remove the transport pro-
tection from the module connector plug of
the module and the protection from the mod-
ule connector socket of the basic device.
Mounting module:
1. Disconnect the system (basic device) from the
power supply!
2. Remove the transport protection from the
module connector plug of the module and the
protection from the module connector socket
of the basic device.
3. Slide the module into the slot on the rear side
of thebasic device and use slight pressure to
press it into thebasic device until the module
connector audibly snaps in.
4. Connect the system (basic device) to the
power supply. The basic device recognizes
the plugged inmodule automatically.
4.2 Module mounting
INFORMATION
The basic device supports the module functions
only if the module is detected during the startup
process (e.g. residual current or DC power)! If
there is no communication with the module:
· Disconnect your system (the basic device) from
thepower supply and check the positioning of
the RCM module. Carefully press the module
onto the basic device until it audibly snaps into
place.
· If necessary, restart the basic device (section
„8.3 Restarting the basic device“ on page 40)!
