4. Connecting DC loads
(Solarix 400 RI / 550 RI / 900 RI only)
Note!
Never connect cable to terminals when consumers are on.
Further the current for DC consumers is limited to 15 A.

5. Connecting AC consumers
-
connect AC connection
cable, assembled as de-
scribed above, to connec-
tor box at appliance
6. Installing strain relief
Fasten all cables 10 cm below appliance using a strainrelief (e.g.
cable clip).
The appliance is ready for service now!
CALIBRATING LOAD DETECTION
After having installed the Solarix, it has to be adjusted to the type of
battery that is used. This is necessary for optimum performance of the
stand-by mode (load detection mode), so that even small loads will be
recognized.
Attention!
The following procedure should be performed
periodically, especially if the load detection threshold shifts with
time as the battery is aging!
-
Disconnect all AC loads from the Solarix. Preferably the AC connection
cable should de disconnected at the connector box.
-
By pressing the operating mode key put the device into sleep mode
(left LED must be dark)
-
Now press operating mode key for at least 3 seconds until left LED
starts to blink rapidly. Release key.
-
The device will now perform an internal calibrating process, the result
of which will be stored in non-volatile memory. The left LED will show
the following sequence: rapid blinking -> approximately 1 second
green -> brief red flash -> calibration finished.
-
the Solarix is ready for service now; defaut is the energy-saving
standby-mode (load detection mode).
-
Re-connect the AC connection cable
If a load is connected to the AC output, the Solarix will switch into
continuous operation. The threshold for successful load detection is
typically in the range of 5-25W, depending on the load characteristics.
If a small load is not recognized by the system, the operating mode has
to be changed manually to “continuous operation”.
