Economy Operation
9.0 Economy Operation
9.1 General
In economy operation the load is supplied directly from the utility, however the
UPS is monitoring the utility and the output voltages and will in case of utility
failure switch to battery operation without interruptions.
The system will in order to keep the batteries fully charged at all times switch to
normal operation in a pre-programmed time sequence.
The operation of the system is the same as already described in this guide with the
exception of the following points:
- When starting up, the system will at first go into normal operation to ensure a
fully charged battery, but will then switch into bypass after the programmed
time (8-10 hours).
