1.3 Safety
The FS Series 3 PV Modules may produce voltage in excess of 70 Volts DC (VDC) and current in excess of 2.2
Amps when exposed to sunlight.
A single module could create a lethal shock hazard during hours of daylight
,
including periods of low light levels. The danger increases as modules are connected together in series and/or
parallel.
To avoid fire and/or injury due to ground fault and associated electrical hazards:
•
Do not unplug PV module connections while under load. Do not disconnect the module connectors during
daylight hours unless the module is in an open circuit condition or all modules in series and parallel are
covered with an opaque material, such as a tarp or blanket.
•
Repair or replace damaged wires immediately. Keep all array wiring out of reach of non-qualified
personnel.
•
Do not concentrate light on the module in an attempt to increase power output.
•
Never allow the PV array open-circuit voltage to exceed 1000VDC under any condition.
•
Replace broken modules immediately.
•
Repair any ground faults immediately.
•
Do not work on modules or systems when the modules or wiring are wet.
Reverse currents higher than the rated values for a First Solar module (reverse current overload), may result in
module failure, including module breakage. Extreme and continuous reverse current overload conditions may
cause a fire or create electrical shock hazards. To avoid reverse current overload:
•
Maintain equivalent voltage in parallel strings by installing an equal number of modules per string within
the same source circuit. Failure to install modules with balanced voltage in parallel strings can result in
voltage imbalance.
•
Comply with all previously noted practices to prevent and repair ground faults.
Wear safety glasses (ANSI Z87.1-2003) and cut-resistant gloves when working on non-interconnected modules or
systems.
Wear electrically rated PPE when working on interconnected modules or system components.
