Troubleshooting
Alarms and problems you may encounter during operating the UPS are given in the table below.
Apply
the suggestions corresponding to each anomaly as described into the table.
If your anomaly is excluded or the suggested actions do not solve your problem, consult the Technical Service.
Please give the following information to the Technical Service:
Model and serial number of the UPS, which can be found on the nameplate on the rear of the UPS.
Description of anomaly.
Risk of electric shock: do not remove the cover. The UPS contains internal parts that are
at a high Voltage and are potentially dangerous, capable of causing injury or death by
electric shock.
There are no internal parts in the UPS that are user serviceable. Any repair or
maintenance work must be performed exclusively by qualified technical personnel
authorized by TECNOWARE.
TECNOWARE declines any responsibility if this warning is disregarded.
Warning to the technical personnel authorized for service: since internal components
are connected to the batteries, they will remain powered, and therefore dangerous,
even after the UPS has been disconnected from AC power mains. Before any repair or
maintenance work, disconnect the batteries, by removing the positive cable (red colour)
from the positive pole of the battery.
