IMPORTANT SAFETY INSTRUCTIONS
Read all instructions, cautionary markings, and all appropriate sections of this installation and user
manual as well as other component manuals before using the system.
Be cautious around electricity, electrical components, and batteries. Shocks, burns, injury, and even
death can occur if an installer comes in contact with electricity. The FLEXware Surge Protector is
designed for dry, indoor installation and should not be exposed to water.
Install all components and wiring according to national (NEC in the United States) and local
electrical and building codes. This includes submitting a plan to the local building department and
passing an inspection.
NOTE: The FW-ACA, which houses the surge protector, is designed as a wireway between FX
Series Inverter/Chargers and OutBack enclosures (508A Industrial Control Panels) including the
FLEXware 500 and FLEXware 1000. The FW-ACA’s knockouts are not intended for conduit, but can
accommodate exible cables with appropriate strain relief.
OutBack Power Systems cannot be responsible for system failure, damages, or injury resulting from
improper installation of their products.
