5.3.1 Resetting the device

The UPS is equipped with internal protections which block the system or some of its
sections. The alarm can be cleared and normal operation can be resumed via the DEVICE
RESET page. In case the failure persists, the UPS will return to the previous failure condition.
In some cases the RESET is necessary to simply reset a failure signal, then the UPS will
resume operation. The failure conditions which impose a manual reset are:
➢ Activation of the battery fault alarm (alarm A10)
➢ Static switch re-transfer block (alarm A17)
➢ Scheduled maintenance request (alarm A29)
➢ Booster shutdown due to the operation of the load symmetry sensor (alarm A33)
➢ Inverter shutdown due to voltage control loop error (alarm A39)
➢ Booster shutdown due to voltage control loop error (alarm A41)
➢ Booster shutdown due to current control loop error (alarm A43)
➢ Block due to the disconnection of one parallel cable (alarm A50)
➢ Block due to the disconnection of two parallel cables (alarm A55)
