2.4 Intended use
Only use the device within the framework of the corresponding technical data. Any operating
conditions that deviate from this shall be considered as improper use. Solely the user of the
device shall be liable for any resulting damage.
Please note the following:
• In case of improper use, the liability and warranty claims become void. Solely the user of the
device shall be liable for any damage resulting from improper use. Uses not complying with
the intended use include e.g.:
– Use of components, accessories, spare or replacement parts that have not been
released and approved for the respective application by Benning
– Non-observance, manipulation, changes or misuse of the operating manual or the
instructions and notes contained therein
– Any form of misuse of the device
– Any use other than or beyond that described in this operating manual
• Warranty and liability claims are generally excluded if the damage is the result of force
majeure.
• If any prescribed services are not performed regularly or not on time, according to the
manufacturer’s specifications during the warranty period, a decision about a warranty claim
can only be made once the findings are available.
Direct any questions to Technical Support [}page9].
Using the device
Please observe the following basic obligations when using the device:
• Before carrying out tests and measurements, disconnect all poles of the PVgenerator from
the PVinverter. The PVgenerator must be isolated from the electric power supply! Neither
the positive nor the negative pole of the PVgenerator must be earthed!
• Make sure that all switching and disconnecting devices are open and all PVstrings are
insulated from each other.
• Please observe that the PVgenerator must not exceed the maximum open-circuit voltage of
1 000V, the maximum short-circuit current of 15A and the maximum DCpower
(P=V
OC
xI
SC
) of 10kW.
• Carry out the tests and measurements only on individual PVstrings. Please observe that
the short-circuit currents (I
SC
) of PVstrings connected in parallel add up and might
additionally increase due to existing capacitances of the PVgenerator.
• Make sure that no power optimisers are installed in the PVgenerator. In the event of a
short-circuit, power optimisers might generate transient current peaks that significantly
exceed the specified short-circuit current (I
SC
) of the PV generator.
• The device may only be used in a technically perfect and safe condition. Always check the
device for damages before using it.
• The personnel must be qualified for the respective task.
• Observe relevant regulations on occupational safety and health as well as those on
environmental protection.
• The device may only be used in dry environments.
• Do not use the device in potentially explosive environments.
• Use suitable (approved) safety measuring lines.
• In order to prevent any danger due to incorrect measurements, replace discharged batteries
immediately.
• In order to prevent any danger, replace a defective fuse immediately.
