3. Product description
Data loggers of the blue’Log X-series record all the data of your PV system to ensure
the function of the system as well as its performance capabilities. Data such as current,
voltage, temperature, output and yield from each individual inverter are measured, as

blue’Log XM / XC
6 | 23
well as values from externally connected sensors. The blue’Log is the interface for grid-
compliant feed-in for PV systems. The X-series is available in two variants: blue’Log
XM and blue’Log XC. blue’Log XM is intended for monitoring purposes. blue’Log XC is
intended for control and regulation ("power control") purposes.
See the blue’Log data sheet for further technical details. Further information about our

before you start work on the blue’Log.
5.1 Intended use
Only the permitted signals and signal strengths may be applied to the connections of
the data logger (blue’Log) and the expansion modules (MX modules) used here.
Installation is only permitted indoors. For installation outdoors or in a dusty
environment, the device must be installed in a standardized protective enclosure.
5.2 Personnel
Installation, commissioning and maintenance of the device may only be performed by a
qualified electrician.
Given their specialist training, knowledge, experience, and familiarity with the relevant
standards and regulations, a qualified electrician is in a position not only to carry out

blue’Log XM / XC
7 | 23
The qualified electrician must comply with the occupational health and safety laws in
force.
Please note in particular:
•All national installation and set-up regulations (e.g. VDE in Germany)
•The generally accepted codes of practice
•Information on transport, installation, operation, service, maintenance and
disposal given in this user manual
•Specific values, limits, and information relating to operating and ambient
conditions on type plates and in data sheets.
Protection concepts
•The memory card (SD memory) must not be removed while the blue’Log is in
operation.
•The blue’Log may not be opened.
•The blue’Log may not be modified.
•Damaged devices must be taken out of operation immediately and checked by
a qualified electrician.
•Local regulations must be observed when using the devices.
•The safety of the blue’Log and the user cannot be guaranteed if the safety
precautions described are violated.
5.3 Internal battery
The blue’Log data logger contains an internal lithium battery (button cell) which ensures
that the time and date remain stored in the device in the event that the power supply is
interrupted.
NOTICE
The housing may only be opened by qualified personnel.
•The battery may only be replaced by the meteocontrol repair
service, since the blue’Log housing needs to be opened.
•meteocontrol GmbH accepts no liability for material damage owing
to non-compliance with this warning notice!

7. Mounting and installation
During installation, all the manuals for system modules and components must be taken
into account.
7.1 Safety instructions for installation
DANGER
Electric shock hazard!
Fatal injuries or death from contact with cables and terminals.
•Only connect or disconnect cables while they are de-energized.
•Take measures to prevent the power cable from being reactivated.
NOTICE
Damage due to improperly connected wires and cables!
Incorrectly connected cables can lead to damage or destruction of the
measuring inputs and the device.
•Connect cables only to the sockets provided for this purpose.
•Observe the polarity while connecting cables.
NOTICE
Damage due to overvoltage!
Overvoltages or surge voltages may damage or destroy the device.
•Protect the power supply against overvoltages.
Voltages of more than 24 V DC and currents of more than 20 mA on the
analog and digital inputs can destroy the respective measuring inputs.
•Ensure that voltages only up to 24 V DC and currents up to 20 mA
are applied.

7.2 Installation
7.2.1 Installing the device on a top-hat rail
Step
Action
1.
Hang the blue’Log on the top-hat rail using the clamp provided (rear panel).
2.
Push the top-hat rail latch on the front side of the device from bottom (latch
open) to top (latch closed). This will attach the blue’Log to the top-hat rail. The
icons (open/closed lock) above and below the top-hat rail latch indicate whether
the device is attached.
3.
Check that the blue’Log is securely attached to the top-hat rail.
Fig. 3: Secure mounting on a top-hat rail
7.2.2 Dismounting the device
To remove the blue’Log from the top-hat rail, push the top-hat rail latch from top to
bottom. The device can now be lifted off from the top-hat rail.
NOTICE
For installation within a control cabinet, ensure at least 3 cm of free space
above and below the device for air circulation.

7.2.3 Mounting MX modules on the device
The blue’Log can be expanded to provide additional interfaces using various add-on
modules (MX modules).
Fig. 4: MX module (example: RS485/422)
NOTICE
Risk of damage when installing add-on modules
Installing MX modules while the blue’Log is operating can damage or
destroy the blue’Log and the MX modules.
•Before installing MX modules to provide additional interfaces,
disconnect the blue’Log from the power supply.
1. If necessary, remove the blue’Log from the top-hat rail.
2. In order to add an MX module to the blue’Log, remove the cover on the right-
hand side. For this, unlock the four fasteners and pull off the cover on the
right-hand side.

Fig. 4: Unlocking the fasteners
Fig. 5: Pulling off the right-hand side cover
Set the side cover aside, as you will need to reattach it to the right side
of the MX module later. This is required in order to fasten the blue’Log
and MX modules to the top-hat rail.
3. You can now see the expansion socket on the right-hand side of blue’Log
housing.

7.2.4 Multiple MX modules
The blue’Log can be expanded with several MX modules of the same type or with
different MX modules. See the data sheet for your basic device for details on the
maximum number of expansion modules.

7.2.5 Connection sequence for MX modules
When connecting MX modules to the basic device, observe the prescribed connection
sequence in order to ensure correct functionality of the modules.
The number of arrows and lines on the bottom front panels of the blue’Log and MX
modules indicates the connection sequence. Modules with a greater number of
arrows/lines may not be installed before a module with fewer lines (e.g. two
arrows/lines). For example, a module with three arrows/lines must not be connected
before a module with two arrows/lines.
