Figure 11-4 – Recommended Mains Cable Routes within 15U Cabinet
The 8U cabinet has space for a pair of 12V batteries up to 17Ah. The
15U cabinet has space for a pair of 12V batteries up to 40Ah.
Many non-brigade-connected systems will require larger battery
capacities to meet the 72 hour standby operation requirements.
Batteries greater than 40Ah (or 17Ah) will require a separate battery box,
which must be located adjacent to the
MX1
cabinet.
The wiring between any external battery cabinet and the
MX1
should use
4mm
2
cable to minimise voltage drop. The lead interconnecting the two
batteries is provided with the panel and includes an inline 20A blade
fuse.
