If you have noticed an abnormality in operation; check the Protective Ground/Earth connections, examine the

suggestions corresponding to each anomaly.
If your issue is excluded or the suggested actions do not solve your problem, consult the Technical Service.
Risk of electric shock: do not remove the cover. The UPS contains internal parts which
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 which 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,

maintenance work to the UPS unit, turn off the Battery circuit breaker on the rear side
of Battery Box unit and then disconnect the Battery cable.
