Chloride Active and E-Series UPS User Manual 3
Chapter 2 Display and Operation Elements (Active)
The Uninterruptible Power System (UPS) is connected between AC power and the load. It protects the load
against mains disturbances, especially power failures.
Its operation is based on the on-line principle. The connected load is supplied power through the UPS’s
inverter. Power disturbances from the mains are suppressed which increases the loads’ operational security
(PC, network server, multi-user systems etc.)
In the event of a mains failure, maintenance-free batteries provide an uninterrupted supply of energy. In
practice, mains failures are of relatively short duration, dependent on the mains quality. Therefore, the UPS’
energy is in most cases sufficient to ensure continuous operation of the connected systems, until the mains
is reestablished. In the event of a longer lasting mains failure it allows for controlled shutdown of connected
systems.
The UPS indicates by acoustical (buzzer) and optical (LED) alarms that a mains failure has occurred and is
still persistent. Battery runtimes vary depending upon load, number of batteries and environmental
conditions.
The following chart shows the approximate values of the emergency runtime (assuming fully charged
battery at the onset of the mains failure.)
Load in % A700 A1000 A2000 A3000
OVERLOAD >105
95-105 6 min 7 min 10 min 6 min
LOAD 75-95 7 min 8 min 11 min 7 min
55-75 10 min 11 min 16 min 10 min
35-55 15 min 17 min 24 min 15 min
1-35 28 min 33 min 37 min 28 min
• The actual battery capacity can be read from the LED-”battery” chain (see table below).
Battery Capacity
Battery 1 - 35%
35 - 55%
55 - 75%
75 - 95%
95 - 100%
The most reliable method for determining actual battery runtime is the application of Chloride MopUPS ®
software. With this software, the prospective remaining battery capacity is indicated before and during an
AC power failure. Furthermore, shutdown procedures can be automated. Depending on the application
program, operating system and computer hardware, it can be ensured that in the event of a power failure the
application programs are automatically closed, the subscribers logged in at the server are logged out, the
data is stored and the operating systems are shut down. For further information please refer to our
publication about the Chloride ManageUPS™
NET SNMP Adapter.
After return of the mains voltage, the UPS automatically initiates a restart. The connected systems are
restarted according to their specifications.
In the event of overload or internal failure, the load is supplied from the mains via an automatic bypass. As
soon as the normal status is reestablished, automatic switchover to inverter operation is performed.
