Operating manual
The relay contacts are closed, if
all string currents are equal,
|
all string currents are flowing in the same direction,
|
negative string currents (reverse currents) are  1 A, and
|
the string currents of all connected strings I < 20 A.
|
2. Check the plausibility of all measured string currents. Note the
following:
The measured current depends, for example on
the solar module type,
|
the type of input configuration (for double-allocation of inputs, there
|
are double the string currents),
the irradiation conditions,
|
the inclination angle of the solar modules.
|
3. Switch the DC disconnect to Off.
The relay contacts are open.
4. Measure every string current. Note the following:
The string currents of all connected strings must be I = 0 A.
|
The string currents have been measured and the relay contacts have been
checked.
