4.2 Electrical Safety
Be familiar with the basic principles of electricity and electrical equipment. Use properly
insulated tools and appropriate protective equipment such as safety shoes and insulated gloves
as well as protection goggles. Do not remove any parts originally installed or disassemble the
module.
Short circuits on the DC side of the installation can cause arcing. This is a burn and fire
hazard. Unlike arcs occurring in conventional low voltage AC wiring, these arcs are not self
extinguishing. The high temperatures generated by these arcs can destroy contacts and
connectors. If not handled and installed according to instructions, solar modules can present a
lethal hazard.

Cover module face(s) completely with opaque material to halt the production of electricity
when working with module wiring.

Disconnect module(s) from other sources of electricity, such as batteries or inverters,
when any work on the installation is being done.

Avoid contact with terminals when modules are exposed to light.

Exercise utmost caution when working on wiring, including the inverter installation.

Do not attempt to install or use a module with broken front cover glass or a damaged
back glass. They represent a shock hazard due to leakage currents, especially when
wet.

Do not connect HS modules directly to motor loads. Variation in PV module output power
as a function of solar irradiance may damage directly connected loads.

Make sure that all electrical connections are completely dry before they are assembled.
Materials, tools and working conditions need to be clean and dry.
