Maintenance - SunTech Power Photovoltaic Module Installation Manual

• Notice that WEEB teeth is positioned completely under the edge of the module
frame.
• When position of solar module is finalized, torque fasteners to 20.5 N-m/15 ft-lb
using general purpose anti-seize on threads.

• When using the GBL-4DBT grounding lug, assemble the grounding lug to
aluminum frame using stainless steel M5 screw and hardware as shown above.The
star washer is fitted directly under the grounding lug and makes electrical contact
by penetrating the anodized coating of the aluminum frame; the screw assembly a
future fitted with a flat washer, then a split lock washer finally a nut to secure the entire
assembley (see the picture above). Recommended M5 screw assembly torque is 1.5N-m.
Next insert the ground wire (10-12 AWG exposed copper wire is recommended) to the
feet of the lug, and screw down the slotted screw. Be carerful not to damage the wire
core.

Maintenance

To ensure optimum module performance, Suntech recommends the following
maintenance measures:
• Clean the glass surface of the module when required. Always use clean water and
a soft non-abrasive sponge or cloth for cleaning. A mild, non-abrasive cleaning agent
may be used to remove stubborn dirt.
• Check the electrical, grounding and mechanical connections every six months to
verify that they are clean, secure,undamaged and free of corrosion.
• In the event of a ground fault condition, NEVER wash or spray modules with water
until ground fault has been identified, corrected by an authorized solar inverter service
technician and the inverter is fully operational. This can cause electrocution or a serious
safety issue.
• If any problem arises, consult a professional solar service providers for suggestions.
• Caution: observe solar manufacturers' maintenance instructions for all components
used in the system, such as support frames, charging regulators, inverters, batteries etc.
