The trip times that can be checked for the autotest match with the values given in the table and detected by
the system, apart from a negligible error.
The autotest procedure is as follows:
•
from the start menu, select the
Tools
(
) icon;
•
use the arrow keys (
) from the status bar to scroll to the second page and select the
Commands
(
) submenu;
•
select the relevant icons from the
Autotest
submenu; carry out the following tests in sequence:
minimum voltage and maximum voltage; minimum frequency and maximum frequency;
•
press the
Run Command
(
) button to enable the test: the trip value starts
varying until it matches with the measured value (see Figure 90);
•
if the test succeeds, the inverter temporarily disconnects from the grid and the test window
shows the value of the trip threshold causing the inverter to stop and the time when the
protection has tripped;
•
if the test fails, the inverter does not stop. This means that the interface protection has tripped.
Please contact the Customer Service of Elettronica Santerno SpA.

Maintenance
The degree of protection IP65 limits scheduled maintenance only to the external parts of the product.
Every two years, clean the external fans and the rear heatsink with compressed air to remove dust. The
frequency of scheduled maintenance may need to be increased depending on the installation conditions. It
is to be increased if the inverter is installed outdoor or in a dusty environment.
It is recommended that the inverter operation be periodically checked using the diagnostic means made
available from the touchscreen display. It is advisable to read the alarm history and to perform the autotest
procedure.
