Chloride Active and E-Series UPS User Manual 29

Chapter 12 Display and Operation Elements (E-Series)

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 % E61 E101 E203

OVERLOAD >105 w/BPE101

95-105 9 min 9 min 15 min

LOAD 75-95 10 min 10 min 20 min

55-75 13 min 13 min 25 min

35-55 21 min 21 min 45 min

1-35 40 min 40 min 90 min

OTE: *E-Series Model E203 does not contain internal batteries.

• 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.
