5.1 COMMANDS AND SIGNALS
5.1.1 Switching on with mains power present
See note
After the mains power supply has been connected, the
internal battery-charger is activated automatically and the
UPS goes into by-pass mode.
Press the ON button for about 2 sec. (until you hear a
beep) to activate the UPS and power your equipment.
After a few seconds for the self-test, the LEDs will be as
shown in the figure on the left.
The mains power supply is regular and constant and the
batteries are in charging or floating. This is normal
operation.
Your application is powered by the UPS and continuous
power is guaranteed.
If the UPS is switched on with mains absent, follow the
same procedure as described above and after the self-test
the UPS will go into battery-powered operation.
The consumers are powered by the batteries, which will
progressively discharge.
An intermittent acoustic and visual alarm will indicate that
the UPS-ENTERPRISE is operating on battery power.
It is recommended to switch on in this way only if the protected
equipment has to be switched on under emergency conditions
and with the minimum indispensable load.
Your application is powered for the residual time given by
the batteries
Note
Under normal conditions (mains present), the associated LED may be flashing, indicating inversion of the phase
/ neutral polarities: in this case, insert the plug the other way to eliminate the problem.
