Requirements and Warnings
The OutBack FW-IOB-D-120VAC is intended as a system compo-
nent and is included in a listing by ETL as indoor enclosures to UL

This enclosure is intended for battery circuits configured for 12 to
48 volts nominal.
Grounding Instructions – Each enclosure should be connected to
a grounded, permanent wiring system. For most installations, the
negative battery conductor should be bonded to the grounding
system at one (and only one) point in the DC system. All instal-
lations must comply with all national and local codes and ordi-
nances. System grounding as required by the National Electric
Code, ANSI /NFPA 70-1996, is the responsibility of the system
installer.
