6.C Electrical Wiring Method
To ensure proper system operation, correct cable connection polarity (Figure 2) must be observed when
connecting the modules to other modules. If not connected correctly, the bypass diode could be destroyed. If
modules are connected in series, the total voltage is equal to the sum of the individual module voltages. Only
connect modules or series combinations of modules with the same voltage. If modules are connected in parallel,
the total current is equal to the sum of individual module current.

6.D Correct Wiring Scheme
Match the polarities of cables and terminals when making the connections; failure to do so may result in
damage to the module.
Avoid immersion of cables and connectors in water and site them away from areas prone to water
collection. Ensure a minimum clearance of 10mm between the ground/roof surface and the
cables/connectors after installation.
Fix the cables/connectors to the module or mounting structure before commissioning the system.
Use the tool recommended by connector manufacturer when disconnection of connector is needed.
Example: open-end spanner PV-MS (Figure 3).
When routing cable, ensure forces on the cable do not create a visible deformation in the sealing portion of
the insulation. Do not create cable bends less than the 26mm minimum bending radius of our cables
(Figure 4)
In order to limit voltages induced by indirect lightning strikes, keep the area of all conductor loops to a
minimum
