3.3.4 Connecting the cables to the charging station
It is imperative that all general safety instructions are observed (Chapter 1.3; Page 3).
It is imperative that the connection sequence described in this Chapter is observed, as this is the only way in which
correct commissioning can be guaranteed
The following sequence of procedures must be adhered to without fail when connecting the charging station:
•
Remove cover from terminals
•
Make holes in ring seals (supplied) and slide over each round cable
•
Connect battery cables to the terminal pairs on the charging station marked with the battery symbol (1-8). A pair of
terminals (+ und –) is planned for each battery cable. It is imperative that correct polarity is observed. The middle
terminal pair is intended for the module.
•
Connect module cables to the middle terminal pair on the charging station - marked with the module symbol.
Observe correct polarity.
•
Place ring seal in the half-cup in the charging station housing.
•
Screw terminal cover back on
•
Now the batteries can be connected for charging.
•
Tip: It is very helpful if the battery cables are marked at the end of the wire with the number of the relevant charging
station channel
3.3.5 Removal
Removal should be carried out in reverse order of installation as described above. First disconnect all the batteries.
Then the modules must be separated from the control unit. In order to avoid sparking, this must be carried out at night or
with the modules covered.
3.4 Safety measures
3.4.1 Flammability
The charging station consists exclusively of non-flammable and self-extinguishing materials. A fire cannot be started
even in situations where an unforeseen fault occurs provided no flammable substances are stored in the immediate
vicinity of the charging station and the charging station is mounted on a fireproof surface.
3.4.2 Precision protection against surge voltage
Lightning protection was not provided in this charging station for reasons of cost and space. Lightning protection must be
carried out when the equipment is installed and must be adapted to local conditions. Measures have, however, been
taken to compensate for excess voltages in the atmosphere. The latter protection is adequate for this application.
3.4.3 Single and double errors
The charging equipment has reverse battery, open circuit and short circuit protection at all inputs and outputs. The
battery output is also protected from overcharge. In addition the MPP-Tracking system prevents input overload.
Suitable measures – mainly electronic – protect the charging station from single errors (e.g. reverse battery polarity
reversal, module polarity reversal etc.).
However some double errors can lead to destruction of the control unit and components connected to it (batteries,
modules):
•
reversed poles module at a battery output
•
an incorrect source (mains supply with 230V) at the solar input
