The loads of 2400 Pa, 3800 Pa and 5400 Pa are under IEC standard. The installation
methods applicable for 5400 Pa are also relevant for 3800 Pa and 2400 Pa. The installation
methods applicable for 3800 Pa are also relevant for 2400 Pa.
**
The module clamps must not come into contact with the front glass or deform the
frame in any way. Avoid shading effects from the module clamps and insertion systems.
Drainage holes in the module frame must not be closed or obscured by the clamps.
***
Measurement A stands for the distance from the module edge to the clamping
zone. Measurement A is 150mm for T series 35 mm thickness, 180mm for W series 35mm
thickness, 280mm for V series 40mm thickness. The clamping zone defines the range for the
middle point of the clamp.

Electrical Installation
General installation
•
Any hardware used must be compatible with any other used material to avoid
galvanic corrosion. Defects caused by corrosions void the warranty.
•
It is not recommended to use modules with different configurations (grounding,
wiring) in the same system.
•
Excessive cables must be organized or fixed in an adequate way, e.g. attached to
the mounting structure by using non-metallic cable ties.
Solar cables, connectors and
juction boxes should not be exposed to water exposure, and snow, and rain or water
submersion for a long period of time(IP65/67).
•
For applications requiring high operating voltage several modules can be
connected in series to form a string of modules; the system voltage is then equal to the
sum of the voltage of each module.
•
For applications requiring high operating currents several strings of modules can
be connected in parallel; the system current is then equal to the sum of the current of
each string of modules.
•
The maximum system voltage is 600 volts or 1000 volts depending on the product
family DC according to standards.
•
The maximum number of series connected modules depends on system design,
the type of inverter used and environmental conditions.
•
Based on the maximum series fuse rating of module and local electrical installation
code, always make sure Suntech PV modules with more than two strings in parallel for
connection are assembled with the appropriate string fuse for circuit protection.
•
There is no limitation on the number of modules that can be connected in parallel,
the number of modules is determined by system design parameters such as current or
power output.
•
To prevent the cables and the connectors from overheating, the cross section of
the cables and the capacity of the connectors must be selected to suit the maximum
system short circuit current. The recommended cable is PV wire with a cross section of
at least 4mm
2
.
•
Caution: do not metalize the cables too tight. Any cable damage caused by cable
management system is not covered under Suntech's warranty.
•
Always refer to the cable manufacturer's bending radius which includes the radius
just behind the connectors.
