aluminium frames for corrosion resistance. In order to properly ground the modules frames, the coating must be
penetrated. Please observe the national standards when grounding. If national standards do not require grounding,
WINAICO still recommends all PV module frames to be grounded to ensure the voltage between the exposed metal
parts (ex. frame) and earth ground is zero in all circumstances.
When installing in North America, a module with exposed conductive parts is considered to be in compliance with UL
1703, only when it is electrically grounded in accordance with the instructions presented above and the requirements
of the National Electric Code. Where common grounding hardware (nuts, bolts, star washers, spilt-ring lock washers,
flat washers and the like) is used to attach a listed grounding/bonding device, the attachment must be made in
conformance with the grounding device of manufacturer’s instructions. Common hardware items such as nuts, bolts,
star washers, lock washers and the like have not been evaluated for electrical conductivity or for use as grounding
devices and should be used only for maintaining mechanical connections and holding electrical grounding devices in the
proper position for electrical conductivity. Such devices, where supplied with the module and evaluated through the
requirements in UL 1703, may be used for grounding connections in accordance with the instructions provided with the
module.

Cleaning and maintenance
As the operator, you should regularly remove dirt from the modules and check if all system components are functioning
properly. The following points should be noted:
Never stand on the module surface. Do not exert any mechanical load on the modules.
Do not clean with water if there is a risk of frost or major differences in temperature between the module,
water and air.
We recommend decalcifying hard water. This will prevent lasting water stains. Remove standing water from
the module.
Do not use abrasive cleaning agents or detergents. Do not scrape off dirt as this may damage the surface of the
module.
Check if all cables and connector accessories are undamaged and properly secured.
PV modules are not shaded by unwanted obstacles or any foreign material.
Mounting and grounding components are tightly secured with no corrosion.
ATTENTION
:
Please make sure that the earth connection is not interrupted or damaged!
ATTENTION
: WINAICO recommends PV systems to be periodically inspected by the installer, or
other
qualified person.
