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 re and/or injury due to ground fault and associated electrical hazards:
• Do not unplug PV module connecons while under load. Do not disconnect the module connectors during
daylight hours unless the module is in an open circuit condion 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-qualied
personnel.
• Do not concentrate light on the module in an aempt to increase power output.
• Never allow the PV array open-circuit voltage to exceed 1000VDC under any condion.
• 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 connuous reverse current overload condions may
cause a re 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 pracces 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.

4 Installaon
4.1 Mounng
Physically damaged modules may cause ground faults and associated electrical hazards. To avoid these
condions:
• Handle modules with care during installaon, as heavy impact on the front, back, or edges could result in damage
to the module.
• Do not stack or carry mulple modules on top of one another aer removal from factory packaging to minimize
the risk of breakage.
• Do not li or pull on modules using lead wires or strain relief wire loops to minimize the risk of wire damage.
Do not install the modules in high wind or wet condions to reduce the likelihood of injury.
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.

Damaged wires, connectors, or juncon boxes may cause ground faults, and associated electrical hazards,
including electrical shock. To avoid these condions:
• Protect unmated connectors from dust and moisture by using sealing caps (not provided, available from connector
manufacturer).

FS Series 3 PV Module User Guide—North America | Page 7 of 13
PD-5-200-03 NA | REV 2.1 | 02771_UG_NA_24OCT12
• Limit module connectors to 10 or fewer plug cycles.
• Do not pull lead wires ght at any me. Aer installaon, the connected wire must not be under stress or tension.
• Do not use juncon box assembly or lead wire strain relief loops to secure excess wire or to bear weight in excess
of a module’s own wire and mated connector pair.
• Connector bodies and cables should not be ghtly secured at both ends to any mounng structure to allow for
thermal expansion and contracon.
• Secure wire or connected components so that no loose wires or components are hanging within 1.5 feet (0.46m)
of the ground in free eld applicaons, and so that wire/components are hanging clear of roof coverings or pooled
water in rooop applicaons.
• Ensure connectors are fully mated.
• Ensure wire securement methods, such as use of cable es, do not damage wire insulaon. The minimum module
lead wire bend radius is 5 mes wire diameter. Observe minimum bend radius specicaons on all other PV
system wiring.
• Ensure wires are not in contact with sharp edges of the mounng structure to avoid abrading the wire sheath.
• Inspect and maintain wire management requirements over the life of the plant.
Modules with dierent FS Series numbers (i.e. FS 2 vs. FS 3) have signicantly dierent electrical operang
characteriscs and should not be interconnected within the same inverter to prevent power output loss and
voltage imbalance condions that may create the risk of reverse current overload.
