Redundancy
N + ... Redundancy level: N+1, N+2.
Note: the redundancy level can only be updated when IEMi Operation Mode is disabled (Enabled: No).
In order to enjoy the benefits of IEMi Operation Mode operation a system programmed for N+1
redundancy requires a parallel installation of at least three UPSs, while four UPSs are required
for N+2 redundancy.
The IEMi Operation Mode must be available on all units in a Parallel System.
In case of RPA Parallel System
If IEMi Operation Mode is currently disabled (No) and Q1 is closed, when programming
it to enable (Yes) the selected configuration will automatically be propagated to all
units in the RPA Parallel System.
If IEMi Operation Mode is currently enabled (Yes) and Q1 is closed, when programming
it to disable (N) all stand-by inverters in the system will be switched on-line.
The activation / deactivation of IEMi Operation Mode is indicated each time in the event list. In order to
force a test of all Inverters in the system, at least 1 minute of normal operation must be programmed
during the week (the Yes/No parameter is automatically disabled if this condition is not satisfied).
In case this minimum time in normal VFI operation is not respected, the IEMi Operation Mode will be
disabled. If the value is "No", the UPS is operating in normal VFI / double conversion mode at all times.
When the UPS is in IEMi Operating Mode the IEMi LED is ON (green light).
NOTE !
The configuration of the activation schedule can only be updated when IEMi
Operation Mode is disabled (Enabled: No).
DAY
For the weekdays from "Monday to Sunday", the edit mode (edit day) allows to define time intervals
when the UPS is operating in IEMi Operation Mode. The hour is given in 24-hour format.
These intervals are defined by:
Start Time:
The hour of the day after which the IEMi Operation Mode is enabled.
The IEMi Operation Mode is enabled until the following "Stop Time" time is reached (the
"Stop Time" time of the same day if this is later than the "Start Time" time, the "Stop
Time" time of the following day otherwise).
Stop Time:
The hour of the day before which the IEMi Operation Mode is enabled.
The IEMi Operation Mode is enabled starting from the preceding "Start Time" time (the "Start Time" time
of the same day if this is earlier than the "Stop Time" time, the "Start Time" time of the previous day
otherwise).
Identical times for "Start Time" and "Stop Time" maintain the existing mode only in case the previous
command was "Start Time" and the following command will be "Stop Time".

Critical Power
IEMi SCREEN (option)
This screen is displayed only when IEMi
Operation Mode is available (option).
Enabled
This parameter (values Yes/No) enables
or disables the IEMi Operation Mode.
If the value is "Yes" and the current time
is in the interval for the current day, the
