1.5.3 Multiple Battery Module Back-up Time at Full Load
Standard EX RT 5/7/11 systems (one Power Module and one Battery Module), offers a standard back-up time of
5 to 12 minutes at full load.
To increase back-up time, it is possible to connect up to 5 additional Battery Modules to the standard system.
See Section 2.8 for connections between standard system and Battery Module (EX RT EXB 5/7/11)

1.5.4 Battery Extension Cable Kit
(6 ft./1.8 m, Part number 86006)
This extended battery cable kit will be used instead of the standard battery cable when Battery Modules (EXBs)
are distant from each other (located in two different enclosures, for instance).
The battery extension cable kit includes a 6 ft. long, straight connector battery power cable, and a 6 ft. long
battery detection cable.
