2. Safety instructions
The instrument is built and tested in accordance with
DIN VDE 0411 Part 1/ EN 61010-1
and has left the factory in perfectly safe technical condition.
To preserve this condition and to ensure safe operation of the device, the user must observe the
notes and warnings given in this operating manual at all times.
Only use the temperature sensors and connecting cables included in the
scope of delivery of the BENNING SUN 2.
Do not apply any electrical contact between the temperature sensors and bare
live parts.
The BENNING SUN 2 is intended for measurements under dry ambient
conditions only.
If it is assumed that correct operation is no longer possible, the device must be switched off
immediately.
Safe operation can be assumed to be no longer possible, if
- the device or the connecting cables show visible damages,
- the device no longer works,
- the device has been stored under unfavourable conditions for a longer period of time,
- the device has been exposed to extraordinary stress during transport,
- the device or the measuring lines have been exposed to moisture.

5. General information
The BENNING SUN 2 is intended for measuring the insolation (solar irradiance) as well as the
module / ambient temperature of photovoltaic systems and solar thermal systems. Additionally,
the BENNING SUN 2 comprises a digital compass for determining the cardinal direction as well
as an inclinometer for determining the module / roof pitch.
The integrated data logger with real-time clock allows the storage of 5000 data records includ-
ing the values for insolation, module temperature and ambient temperature as well as a time /
date stamp. The measuring interval of the data logger can be set from 1 minute to 60 minutes in
increments of one minute. The data of the data logger can be read out via the integrated USB
interface and by means of the download software on the enclosed CD-ROM.
