Energy Manager The 'Energy Manager' function can be used to control the floating switch contact so that
(in the Relay this acts as an actuator.
Menu) A consumer connected to the floating switch contact can therefore be controlled by assign-
ing a switch-on or switch-off point depending on the feed-in power (effective power).
The floating switch contact is automatically switched off,

To activate the Energy Manager function, select 'E-Manager' and press the 'Enter' key.
When the 'Energy Manager' function is activated, the 'Energy Manager' icon is shown at
the top left of the display:

Permanent As soon as "Permanent" mode is selected, the relay will be switched
on. As soon as the power module reports an error and switches from
regular grid power feed operation to an error state, the relay is opened.
This way, the relay can be used for fail safe functions.

Application example

When using single-phase inverters at a multi-phase location a phase
equalization might be necessary. If an error occurs with one or more
inverters and the connection to the grid is disconnected, the other in-
verters must also be disconnected in order to maintain phase equilib-
rium. The "permanent" relay function can be used with the
datamanager or an external protective device to detect or signal that
an inverter is not being supplied or is disconnected from the grid, and
that the remaining inverters should also be disconnected from the grid
via remote control.
Active output:
ON: The floating NO switch contact is constantly switched on while the in-
verter is operating (as long as the display lights up or displays).
OFF: The floating NO switch contact is switched off.
Energy Manager:

in the following "Energy Manager" section.
1000 W
set switch-off point up to the inverter's nominal output (W or kW)
500
0 up to the inverter's set switch-on point (W or kW)
when no current is being fed into the public grid by the inverter;
when the inverter is manually switched to standby mode,
when there is an effective power assignment < 10% of the inverter's nominal output.
