Chapter 5 Operational Characteristics
5.1 Ready for Operation Check
To check the emergency supply feature of the UPS, it must be disconnected from the mains.
When correctly functioning with charged batteries, an acoustical signal in intervals of 4 seconds will be
heard. The LED “LINE” (line voltage) indicator disappears. When the interval between the acoustical
signals is reduced to 1 second, the UPS will supply energy for a maximum of 3 more minutes before it is
automatically switched off.
The load will be supplied from the batteries during the specified emergency supply period. If this is not so,
then please check in chapter 8 “Troubleshooting” on page 28.
Reconnect the UPS with the mains.
The UPS is now again ready for normal operation. Please note, that the batteries have to be recharged before
the complete emergency supply period is again available.
5.2 Self Test
The self test is a LED test.
With the UPS connected to the AC power, switch | has to be operated for at least 1 second.
• Acknowledgment of the input is given by a single acoustical signal.
• The elements of the LED “BATTERY” chain are illuminated according to the battery’s load status. The
“LINE” and “BYPASS” indicators are illuminated.
• Initially all elements of the LED “LOAD” chain are illuminated. Beginning with the top indicator, all
elements of this chain will extinguish one after the other. Thereafter the elements are on according to the
UPS load status.
• The “BYPASS” indicator turns off after approximately 5 seconds and the “Inverter” indicator
illuminates. The load is supplied through the inverter, the energy is taken from the mains.
