IEMi Operation Mode screen (option)
This screen is displayed only when IEMi Operation Mode is
available (option).
Enabled (Y / N / Wait)
Y/N
This parameter (values Y/N) enables or disables the IEMi
Operation Mode.
If the value is Y and the current time is in the interval for
the current day, the IEMi Operation Mode is active.

Redundancy
N + …
Redundancy level: N+1, N+2.
Note:
the redundancy level can only be updated when IEMi Operation Mode is disabled (Enabled: N).
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.
If IEMi Operation Mode is currently disabled (N) and Q1 is closed, when programming it to
enable (Y) the selected configuration will automatically be propagated to all units in the
Parallel System.
If IEMi Operation Mode is currently enabled (Y) and Q1 is closed, when programming it to
disable (N) all stand-by inverters in the system will be switched on-line.
When programming IEMi Operation Mode for scheduled activation, IEMi must be left inactive for at least 1 minute
the week (otherwise, IEMi Operation Mode cannot be enabled).
This configuration forces a weekly test of all Inverters in the system.
DAY OF WEEK (d1 ÷ d7): Enabling time in function of weekdays
Note:
the configuration of the activation schedule can only be
updated when IEMi Operation Mode is disabled (Enabled: N).
For the weekdays from d1 to d7 (Saturday to Friday) 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.
Status of the LCD Home Page with UPS functioning in IEMi Operation Mode.
These intervals are defined by:
IEMi START:
The hour of the day after which the IEMi Operation Mode is enabled.
The IEMi Operation Mode is enabled until the following IEMi STOP time is reached (the IEMi STOP time of the same
day if this is later than the IEMi START time, the IEMi STOP time of the following day otherwise).
IEMi STOP:
The hour of the day before which the IEMi Operation Mode is enabled.
The IEMi Operation Mode is enabled starting from the preceding IEMi START time (the IEMi START time of the same
day if this is earlier than the IEMi STOP time, the IEMi START time of the previous day otherwise).
Identical times for IEMi START and IEMi STOP maintain the existing mode only in case the previous command was
IEMi START and the following command will be IEMi STOP.
HOURS / DAY:
The number of IEMi Operation Mode hours per weekday (from d1 - Saturday to d7 - Friday) is displayed in the
operation mode parameter window (ceiling value).
