The back of the charging station must be mounted on a fireproof surface with the cable
openings facing downwards. There must also be no flammable material underneath it when
mounted.
The charging station is designed for mounting on vertical walls. This is the only way the
charging station can be adequately cooled by rising air (chimney effect) and so function
properly. In order to ensure proper ventilation the charging station must not be obstructed.
Clearance of at least 200mm must be observed.
3.2.2 Fixing the charging station
First mark the position of the holes with the enclosed drilling template, then drill holes and if
required insert plugs into the wall. Screw all four screws into the wall leaving 8-10mm. Hang
the charging station fixing plates onto the screws and tighten the screws.
The charging station must only ever be used as a marking template and
never as a drilling template
Once the charging station has been screwed to the wall wiring can be commenced.
3.3 Cabling
3.3.1 General points
Photovoltaic modules generate electricity when they admit light. Even with a low incidence of light the voltage is at its full
level. Provide the photovoltaic modules with a cover that is impervious to light, holding it in place with sticky tape. The
modules can be rendered dead by covering them.
•
Under no circumstances must the photovoltaic modules be switched to dead by means of a short circuit.
Sparking will occur!
•
Only use properly insulated tools!
•
Never touch bare lead ends!
•
Insulate immediately every bare lead end that is not going to be connected straight away!
•
Only carry out installation work on a dry surface! Components (photovoltaic modules, cables etc.) must not be
wet or damp during installation!
•
It is imperative that correct polarity is observed during the cabling process!
N.B.:
Earthing of components in island units is not necessary, not usual or can be forbidden by national regulations (e.g. DIN
57100 Part 410 Ban on earthing protective low voltage circuits).
3.3.2 Cables required
(These measures only apply if no cable tree has been purchased.)
A plus and a minus cable, both round (
∅
ca. 6.7mm), each with a cross section of 16mm² should be provided for the
supply lines from the solar generator. Also the module junction box should not be more than ca. 15m away from the
charging station.
A round cable (
∅
ca. 7.5mm) should be provided for each battery with two isolated conductors for the plus and minus
lines. Each isolated conductor should have a cross section of 2,5mm². Also the batteries should not be further than ca.
10m away from the charging station.
Before making a start on cabling check that the planned modules are suitable and have the correct circuits (check unit
voltage of 24V).
3.3.3 Preparation
(These measures only apply if no cables have been purchased with the unit.)
in principle all the cables must be prepared before connection:
•
Cut into sections
•
Strip both ends and if necessary press on end sleeves or fit suitable pole shoes or holders for the batteries.
