2 SAFETY
All instructions and safety information should be read and understood before attempting to handle, install, or
electrically connect First Solar modules. Failure to follow safety, installation, and handling instructions may
result in injury. Only qualied personnel should install, operate, or maintain PV modules or systems.
Series 6 Modules are designed for 1000V systems at altitudes up to 5000 m (16404 ft) and 1500V systems
at altitudes up to 3000 m (9842 ft) per IEC 61730-1.
Select installation locations and module support structures to ensure modules and connectors (open or
mated) are never submerged in standing water.
DANGER The Series 6 Modules may produce up to 275 Volts DC (VDC) and up to 4.0 Amps when exposed to
sunlight. A single module or multiple interconnected modules can create a lethal shock hazard
during daylight hours, including periods of low light levels. The danger increases as modules are
connected together in series and/or parallel.
DANGER
To avoid re and/or injury due to ground faults 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.
`Replace modules with damaged wires immediately. Keep all array wiring out of reach of non-qualied
personnel.
`Do not concentrate light on the module in an attempt to increase power output.
`Never allow the PV array system voltage to exceed 1500VDC under any condition.
`Replace broken modules immediately.
`Repair ground faults immediately.
`Do not work on modules or systems when the modules or wiring is wet.
`All building mounted PV systems should utilize Ground Fault Detector Interrupters (GFDI) and ARC Fault Circuit
Interrupters to minimize risk of electrical shocks and res.
Series 6 Modules have a maximum series fuse rating of 6.0A as dened by UL 1703 and a maximum
overcurrent protection rating of 6.0A as dened by IEC 61730-1/IEC 61730-2. PV systems should be
designed to comply with and provide module overcurrent protection consistent with local codes.
