CONNECTION

The polarities ( + and – ) of solar panel and batteries are absolutely to be observed!
Observe the cross-sections and length measures of the cables!
Connection of the solar controller to the battery »Board I« should be effected first�
Cable Protection: the fuses near the batteries into the + cables (protection against
cable fire)!
The solar panels should be protected from direct sunlight (by covering or shading)
prior to connection�
Main Battery »MAIN I« (must be connected):
Connect the battery connections of the controller – (Minus) and + (Plus) to the
12 V main battery, observing the correct polarity and the cross section of the cables
(refer to connection plan)�
Never operate the controller without the battery »Main I«� If the battery is not con-
nected, the unit will not deliver a defined output voltage�
In case of wrong polarity of battery I, the internal safety fuse will be released�The
replacement fuse should have the same capacity, and it should be of the same type
(car fuse)!
Parallel charging of two or several batteries of the same voltage (12 V) is admissi-
ble� The batteries are to be »paralleled«
Solar Panel (must be connected):
Shade the panels to minimize sparking during connection and to avoid damages
due to eventual wrong polarity� Observe the cable cross-sections (refer to connection
plan)! If several small solar panels are used, they are connected in parallel (refer
to connection plan)� Partial shading of the panels results in average higher capacity
(see connection plan)�
Starter Battery »START II« (Option, can be connected):
Connect the second charging port to the second battery using the red connec-
tion cable (wire cross section 1�5 – 2�5 mm²)� This cable may be longer� In case
of non-utilization, this terminal is left free� If used, the output for starter battery II
will be working with reduced voltage and charging current rates� Thus, the valuable
solar power will be supplied to board/solar battery I being more suitable� However,
the vehicles starter battery II will be kept in a condition, that starting will always be
possible, even in case of longer downtimes and during winter operation�
Connection of the negative pole »START II« is not required, if the negative pole
»BOARD I« is connected to the vehicle body� Depending on the length of the cable,
it may also be connected to the common negative connection of the solar controller
or to the negative pole of »BOARD I«�
