Code Alarms Meaning
4570 OVERLOAD
The UPS-System is in an overload condition >125% on
Inverter, or >150% on Utility.
With Utility unavailable, a sequence of “stop operation”
starts.
Time out depends on Load quantity.
4571 OVERLOAD: LOAD ON UTILITY
With Utility Bypass supply available and load >115%,
the Load is transferred on Utility.
Load will be transferred again automatically on Inverter
when Load <100%.
4581
INVERTER AND UTILITY NOT
SYNCHRONIZED
The voltages of Utility and Inverter are not
synchronized, which causes the opening of K6.
4608 ECO CONFIG FAILURE
The propagation of the eBoost / IEMi configuration to
other units in a Parallel System failed.
4681
MAIN BOARD BATTERY CHANGE
NEEDED
Notice to replace the Lithium Battery located on the P3
- IM0007 Control Board.
4682 DC CAPACITORS CHANGE NEEDED Notice to replace the DC Capacitors.
4683 AC CAPACITORS CHANGE NEEDED Notice to replace the AC Capacitors.
4684 FAN REPLACEMENT NEEDED Notice to replace the Fans.
4685 SERVICE MAINTENANCE OVERDUE Notice to do the Service Maintenance.
4697 BATTERY OVERTEMPERATURE
Detection of Battery over temperature condition.
Can be deactivated by Service Center.
4698 BATTERY POWER INSUFFICIENT
In case of Utility Failure, with the actual Load, the run
time would be below stop operation time (default 3
minutes).
4700 DC LOW
Battery voltage is at the lowest limit.
Will stay Off Inverter until the battery voltage reaches
the value in parameter.
4701
POWER SUPPLY BOARD
FAILURE
Failure detection on the +24V derived from the DC-link
voltage.
4900 LOAD LOCKED ON INVERTER
The Load is locked on Inverter after 3 Load transfers
within 30 seconds.
After time out (default 30 seconds) Bypass will be free.
4955 OVERTEMPERATURE
An over-temperature condition has been detected on
Inverter.
Elapsed “stop operation” time, Inverter shutdown.
With Utility OK, Load is transferred on Utility.
4998
LOAD OFF DUE TO EXTENTED
OVERLOAD
Load Off after time-out of “stop operation” for overload
on Inverter or Bypass (time depending on the % of
overload).
4999
LOAD OFF DUE
TO LOW BATT. OR TEMP.
Load Off after time-out of “stop operation” with missing
Utility due to Battery low voltage or over-temperature
condition.
