1 Notes on this operating manual
This manual is a key aid when it comes to ensuring proper operation of the device. It contains important
information and safety notes to help you use the devices correctly, economically and in the intended
manner.
The manual helps to avoid dangers, to reduce repair costs and downtimes, and to increase the reliability
and operating life of the devices.
During installation, all the manuals for system modules and components must be taken into account.
2 Safety instructions for operation
2.1Intended use
Only the permitted signals and signal strengths may be applied to the connections of the data loggers and
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.
2.2Personnel
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 work on electrical systems but also
to recognize and avoid possible dangers unaided.
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),
§all generally accepted codes of practice,
§information on transport, installation, operation, service, maintenance and disposal
given in the documentation for the devices used,
§specific values, limits and information relating to operating and ambient conditions on
type plates and in data sheets.

4 Cabling
4.1RS485 and RS232/422
The two RS485 and RS232/422 interfaces are used to query information recorded on various bus devices
such as inverters, power quality analyzers, etc.
The RS232/422 interface can also be used as an RS485 interface. In order to do this the interface has to
be operated in RS422mode (for this, please refer to the manual of your IBC-SolControl data logger).
Which interface you should use to connect inverters and accessories depends on your specific driver.
Please refer to the appropriate driver datasheet
Please note the following regarding thebus cabling:
§All devices on a bus must use the same protocol to communicate.
§The data logger functions exclusively as a master on the bus.
§The maximum permitted number of bus devices has to be observed (see driver
datasheets).
§The order of the bus devices on the busis unimportant.
§The use of a repeater is necessary for every 32nd bus device and for long cableruns.
§The bus should be cabled with a twisted and shielded pair of wires.
§The shield of the bus cable must be grounded at one end of the connection only. The
data logger does not have its own grounding
§When you wire the bus wires, make sure that AC andDC cables are routed separately.
§Do not switch the buses signal wires.
§Different manufacturers interpret the RS485 interface’s underlying standard differently.
A and B wire labels may be different for different manufacturers. The + and –indicators,
on the other hand, are unambiguous.
§To prevent reflections, the bus must always be terminated with a parallel terminator.

Daisy chain
If you want to connect more than one device to the bus, you must daisy-chain the connection. This means
that different devices can only be queried jointly if they use the same communication protocol and the
same serial communication parameters (baudrate, data bits, parity, stop bits).
The first and last device on the bus must be terminated with a resistor. The data logger is provided with
integrated terminating resistors that are permanently activated.

8
Star wiring
Another possible way of operating multiple devices on the RS485 bus is called star wiring. In this wiring
variant, a HUB 6 Port RS485 S is used to seperate the bus into a serveral bus strings. To connect the
HUB 6 Port RS485 S to the IBC SolControl, pleaseuse a Connect Universal RS cable.
Various devices can only be queried together if they communicate with the same protocol and have
identical serial communication parameters (baud rate, number of data bits, parity, stop bits).
Each bus string can have a maximum length of 1200 m. All the devices on the same bus string are wired
together in a daisy chain. The first and last device of each bus string must be terminated with a resistor.
The HUB has integrated terminating resistors at each interface, which are permanently activated.
In this wiring variant, the total number of bus devices may not exceed the maximum permissible number of
bus devices.

§The sensor outputs (power signal) must have a resistance of approx. 500 Ω for a
correct measurement. Since the data logger has an internal load resistance of 70 Ω, we
recommend you to install a commonly available 430 Ω load resistor on the sensor
output.
§Pyranometers can be used to measure irradiance either on the horizontal plane or on
the module plane.
