out maintenance work on the modules.

• Do not touch the terminals while the module is exposed to light.

• Install with suitable protection to redirect a discharge of 30 or more direct current

volts to if delivered any person on the installation team.

• Please prevent adherent of oil such as paraffin liquid, animal oil and vegetable oil form

molding parts. It may be cracked or broken and loose the performance of Junction

Box and connectors.

BenQ Solar PV modules have a clearly marked grounding hole on each side of the frame for

inserting the ground contact. The grounding screw and bolt are separately used from the

mounting parts of the module.

Please make sure the grounding screw removes the anodizing from the surface of the

grounding holes, or scratch off the anodizing before the grounding connection is made since

the frame is fully insulated by anodizing.

An anti-oxidation compound should be applied to the bare aluminum surface for protection.

Using a layer of insulation is an especially critical step if the material of support structure is

different with the material of frame (aluminum).

If the support structure be a non conductor, a ground cable must be connected by means of a

suitable fastening system. The fastening system will be joined to a cable with a minimum

2.5mm

cross section, together with all the grounding conductors from each module. Please

make sure that each module is grounded properly. The recommended assembly of grounding

screw is shown below in Figure 5.

Per NEC 250.136, electrical equipment secured to and in electrical contact with a metal rack

or structure provided for its support and grounded by one of the means indicated in 250.134

shall be considered effectively grounded.
