WArning:
• In normal operating conditions, the green MAINS LED [2] is lit.
• During operation with battery power, the yellow BATTERY LED [2] is lit.
• The UPS indicates it is operating with battery power by emitting a slow acoustic sound
(one beep every 12 seconds).
Battery reserve, i.e. the opportune moment for the user to shut down the open procedures
on the computer connected to the UPS, is indicated by an alternating, slow-fast
intermittent sound together with the corresponding flashing of the yellow BATTERY LED
[2]. The end of battery autonomy is signalled by the flashing of the yellow BATTERY LED
and the continuous sounding of the buzzer for a total length of 15": in this state, the load
is no longer supplied.
• The red ALARM LED flashes to indicate the presence of an excessive load on the output.
In this case, if mains is present, the load is supplied through the bypass with mains power, otherwise
the operation of the UPS will be blocked after 15 seconds of continuous overload.
If the red ALARM LED [2] flashes with a rapid intermittence it signals a fault in one or more of
the power modules; if the intermittence is alternating short-long it signals an anomaly in the
connection of the UPS (wrong connection of neutral conductor).
If the neutral is wrong invert the plug on the UPS power supply cable.
• In all cases, when the operation of the UPS is blocked due to any anomaly, it completely and
automatically shuts down after approximately 15 seconds.
