Service life

To determine the service life of a specific configuration, the current consumption of all available expert modules must be summed, refer to the following table. Place the value as determined in the equation below. The result will be the expected service life in days for a given system configuration.

Where I is the total battery current load of all modules in the rack (in A).

The following table shows the modules and their associated current consumption:

Module	Current Consumption (A)
ERT 854 00	70
ESI 062 00	150
ESI 062 10	150
MMB 102 00	200
MMB 104 00	200
MMD 102 00	200
MMD 104 00	200

Calculating Service life example

Considering that the XCP 900 00 battery box provides battery backup for the RAM ESI 062 10 and two MMB 102 00 modules.

The service life can be calculated as follow:

NOTE: If a module is operated from two batteries, the service life is also doubled.
