Up to 4 plus pole strings and 4 minus pole strings can be connected to
each device.
Possible earthing of the solar generator
When using some thin-film modules as well as special solar modules with
contacts on the rear, it may be necessary to earth the solar generator.
Please contact the manufacturer of the solar module to check whether this
is required.
Risk of fatal injury due to earthed solar generator!
A fault in the DC cabling can cause a short circuit or arcing. If there is an
insulation fault in the solar generator, touching the solar generator can
cause death or serious injury. The risk of fatal injury is increased in an
earthed solar generator. Service engineers must be advised of the earthing
so that they can operate accordingly in the event of malfunction.
Clearly mark earthed solar generators.
|
If you have to earth the solar generator, use the supplied jumper (terminal
X23, see circuit diagram).
Please note:
Only insert or remove the jumper when the device is completely de-
|
energised.
The earthing of the solar generator must satisfy the applicable safety
|
regulations, standards and local regulations.
It is possible to earth the solar generator at both poles.
|
Earthing of the solar generator is permissible only in conjunction with
|
a galvanically isolated transformer coil.
Ensure that you have the required specialist knowledge or contact an
|
expert.
In the Extras submenu of the device display
|
adjust the earthing of the solar generator,
|
define the behaviour of the device in the event of an earthing fault.
