6.3 External Backup Battery Installation
In case of power failure, the external backup batteries automatically maintain uninterrupted
power to the Vertical SUMMIT IP System. The external batteries must provide 24V DC; this
is generally accomplished by connecting two 12V batteries in a series arrangement as
shown in Figure 6.3-1. It is strongly recommended that a fuse (10A@250Volts) be installed
as over-current protection. Both the SUMMIT IP KSU and EKSU should be connected to
separate back-up batteries.
Figure 6.3-1 External Backup Battery Installation
To wire the Battery Back-up,
1. Using the Battery Back-up cable provided, connect the Red wire to the positive
terminal of one of the batteries.
2. Connect the Blue wire of the connector to the negative terminal of the second
battery.
3. Connect the non-terminated negative and positive battery terminal s together with a
fuse (10 A @ 250 Volts). This series connection will provide the 24 VDC required by
the SUMMIT IP Battery Backup circuit.
4. Insert the Battery Backup connector in to the ‘BATT’ connector.
5. Repeat Steps 1 to 4 for the EKSU.
NOTE
Battery operation is controlled by the PSU. The PSU will provide charging current to the
batteries during normal AC power operation at a maximum of 200mA. PSU battery
operation will be halted if the AC power is re-connected or if the battery voltage is too low
to maintain full-system operation.
