Installation And User Manual SCHOTT Solar Photovoltaic Modules Tips for the installer
PLEASE READ THIS MANUAL CAREFULLY BEFORE INSTALLING OR USING THE MODULES. This manual contains important safety instructions for the PV module that must be followed during the installation and the maintenance of PV modules. Failure to follow these instructions may result in bodily injury or damage to property. Working on a photovoltaic system requires specialized knowledge and should only be attempted by qualified professionals. Introduction Thank you for choosing a SCHOTT POLY™ photovoltaic (PV) module.

Danger of Death from Electric Shock The 1. 2. 3. inverter can produce dangerous, high voltage. Be sure to follow all manufacturers’ instructions before installing any PV modules. Use extreme caution when wiring or installing inverter. Be sure to shut down inverter before installing or removing PV modules. Danger of Death from Electric Shock When exposed to light, PV modules produce direct current. When disconnecting any PV modules from a string, a deadly arc can occur. 1.
1.3 Installation Safety 1. Always wear protective head gear, insulating gloves and safety shoes (with rubber soles). 2. Due to the risk of electrical shock, do not perform any work if the terminals of the PV module are wet. 3. Do not install PV modules in the rain, snow or windy conditions 4. Insert interconnect connectors fully and correctly. Check all connections. Cables should be secured to the PV module frames, support structure or raceway to prevent movement. Keep connectors out of direct sunlight.
1.6 Mounting and Installation There are several approved ways to mount the SCHOTT POLY™ modules to a support structure. They may be mounted in either portrait or landscape orientation using either the bolt holes provided or using frame clamps (not provided). For all mounting methods a minimum gap of 1/4” (7 mm) between modules is required to allow for thermal expansion. For roof mounted systems a minimum gap of 1” between the module and the roof surface is required to allow for greater ventilation.

2 PV MODULE ELECTRICAL INSTALLATION All SCHOTT POLY™ modules are pre-wired with (2) Tyco 4 mm2 PV1-F 90°C UL listed wire and terminated with Tyco Solarlock connectors. This wire intended for interconnection wiring of grounded and ungrounded photovoltaic power systems as described in Section 690.31(A). MINUS is indicated on connector, POSITIVE is not marked. Make sure that all connections are not under load while being connected.

3 MAINTENANCE SCHOTT PV modules are designed for long life and require very little maintenance. If the angle of the PV module is 5 degrees or more, normal rainfall is usually sufficient to keep the module glass surface clean under most weather conditions. If dirt build-up becomes excessive, clean the glass surface only with a soft cloth using water. Do not use high pressure spray or chemicals to clean the modules.
