Use PV rated solar cable for wiring and suitable connectors only. Ensure that they are in
perfect electrical and mechanical condition. Use only single wire cables. Select a suitable
conductor diameter to minimize voltage drop.

Please note the following instructions:
• The module must be installed so that air can freely circulate around it. Keeping the
cells' operating temperature low will allow for the best possible performance. The
module's performance will be enhanced.
• Do not install modules in systemic and ongoing shade; this can cause the temperature
of exposed cells to rise, reducing output, and may stress conductive bonds in module.
• The DC conductors must be properly gauged so that the voltage drop does not
exceed 2% of the nominal voltage.
• BenQ Solar PV modules are supplied with or without cables, according to where they
are ordered. If supplied without cables, it is recommended that cables with cross
sections between 4 and 10 mm
• The cables allow easy handling while providing high protection against overloads and
short-circuits. They are made of flexible Cu conductors, cross linked insulated
polyethylene and coated with polyvinyl chloride or similar insulation. The insulation is
flame, acid and alkali resistant and should be stored in an area free of any corrosive
gases.

• The modules should be handled and installed by qualified persons only.
• Keep all panel connectors dry and clean at all times. Do not attempt to establish an
electrical connection with wet, soiled, dusty/dirty, or otherwise faulty connectors.
• Unconnected connectors must be covered/protected at all times to prevent dust,
foreign particles, etc. from accumulating within prior to connection.
• Do not allow unprotected connectors to rest on the ground or roof surface.
• Do not climb up or walk on the module.
• Do not drop the module or throw objects on the module.
• Use the module only for the purpose to which it is designed.
• Do not dismantle the module or remove any part, label, or piece assembled by the
manufacturer without the manufacturer's authorization.
