5 Electrical connection
Danger of death through electric shock!
Touching live parts can result in death.
Make sure the polarity is correct when connecting
the modules. Reverse polarity can lead to destruction
of the protective diodes.
Before installing check junction box, the cables and
connectors for obvious damage.
For safety reasons the junction box must not be
opened.
Do not use the plug connectors if the plug contacts
are dirty!
Do not install damaged solar modules!
The solar modules, and in particular the connectors
and tools, must be dry during installation.
In exposed locations, installation of lightning protec-
tion is recommended. If lightning protection equip-
ment is already present, the solar modules must be
integrated properly. Follow the respective current
regulations.
During normal conditions PV module may supply a
higher current and/or voltage than specified under
test conditions.
For determining the voltage design values of the
components, the current design values of the con-
ductors, the ratings of the fuses and the control units
connected to the solar module output, the values of
ISC and UOC specified on the module should be multi-
plied with a factor of 1.25.
The solar module is equipped with high-quality solar
cables and the Tyco plug connector system, which
is protected against reverse polarity and accidental
contact. The connection polarity is marked.
The minimum cable cross-section should be 4 mm2.
5.1 Tyco Solarlok plug connector system
The Solarlok plug connector system is designed for
convenient, reliable connection of individual solar
generators and the Solar Inverter.
Plug connections
The positive/negative coded connectors are marked
with polarity symbols and a coloured ring (blue =
negative, red = positive. They are equipped with
coding ribs for assignment, which ensure that only
connectors of the same polarity can be connected to
each other.
Connecting socket and plug:
The system is only correctly locked if the locking
hooks are recessed flush in the mating piece.
CAUTION
The plug connectors must not be disconnected or
connected under load current! They may be con-
nected and disconnected while voltage is present.
Release the locking mechanism by pressing on the
ribbing of the locking hooks and pulling the connec-
tors apart.
5.2 Application class
Sunways Solar Modules conform to application class
A according to the international safety standard
EN 61730 and therefore meet the requirements of
protection class II.
Sunways Solar Modules can be used in systems with a
DC voltage in excess of 120 VDC.
5.3 Earthing of the modules
An overview of the solar module can be found in sec-
tion 2, Your Solar Modules. A diagram indicates the
holes for connecting the earthing cables.

Proceed as follows to ensure correct earthing of the
modules:
1. Place the lock washer (4) and the ring terminal
with the earthing cable (2) over the earthing hole
(3) on the front of the module.
2. Insert the fastening screw M6 (1).
3. Then push the spring washer (6) from the under-
side of the module onto the fastening screw (1)
and fasten the nut (7).
6 Care and maintenance
Check your solar generator approx. every three years
for soiling. This occurs especially on the lower edge
of the modules and forms a haze that cannot be
washed off even by heavy rain.
In the event of significant dirt build-up we recom-
mend cleaning the glass surface. Use plenty of
lukewarm water and a soft brush. This prevents loss
of yield.
CAUTION
Do not use strong cleaning agents and metallic
objects, in order to avoid damage to the hardened
glass surface!
Occasionally check the cables for damage, corrosion
and make sure they are secure.
