Electrical Installation - SunTech STP280-24/Vd Guia De Instalacion

Mechanical Installation
Pole mount
When installing a module on a pole, choose a pole and module
mounting structure that will withstand anticipated winds for the area.
E
General installation
Module mounting must use the pre-drilled mounting holes in the frame.
The most common mounting is achieved by mounting the module using the
four symmetry points close to the inner side on module frames.
If excessive wind or snow loads are expected, all eight mounting holes must be
used
Do not lift the module by grasping the module's junction box or electrical leads.
Do not stand or step on module.
Do not drop module or allow objects to fall on module.
To avoid glass breakage, do not place any heavy objects on the module.
Do not set the module down hard on any surface.
Inappropriate transport and installation may break module.

holes must also be used

Electrical Installation

This guide describes some of the most important typical uses as representative examples.
Grid-connected electrical system
The DC electrical energy generated by photovoltaic systems may also be converted to AC and connected to a utility grid system. As local utilities' policies on connecting
renewable energy systems to their grids vary from region to region.
Consult a qualified system designer or integrator to design such a system. Permits are normally required for installing such a system and the utility must formally approve and
inspect such a system before it can be accepted.
Grounding
The module frame must be properly grounded. The grounding wire must be properly fastened to the module frame to assure good electrical contact. Use the recommended
type, or an equivalent, connector for this wire.
If the support frame is made of metal, the surface of the frame must be electroplated and have excellent conductivity.
We recommend the lay-in lug(Cat. No. GBL4-DBT is recommended by Suntech) when grounding.First strip 16mm insulating jacket from the end of the ground wire carefully to
avoid nicking or cutting conductors, insert the wire to the feet of the lug (see the picture), and screw down the slotted screw. Be careful not to damage the wire core. And then
tighten up the screw.
