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).
• 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 0.46m (1.5 feet)
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.
