Orange curve:
battery current
The current from the battery increases while the battery voltage sinks (the power in the
buffered supply remains constant).
Grey and yellow: "Status: Warning" and "Status: Critical" are based on the battery voltages
13.2 V (warning) and 12.8 V (critical warning). The measurement makes it clear that a fully
charged battery has sufficient reserves for several subsequent buffering processes.
Even when the battery reaches a low charge, buffering capacity is still available.

Battery Extension Cable
Using an extension cable, the battery can be located away from the device; the extension
cable must be connected between the battery and the ETV 1591-H.
However, the cable and the additional connector must be included in the calculation of the
battery voltage measurement. The UPS calculates the voltage drop.
The UPS is configured via the Windows service "SigmatekUpsMonitor". For the configura-
tion of the cable type, see the chapter "Named Pipe Write Functions".
Order number for the battery extension cable (1 meter): 01-940-010
5.9
Battery Exchange
The "SigmatekUpsMonitor" method to evaluate the battery for the "Battery exchange need-
ed" status and instructions for exchanging it.
5.9.1
Exchange Battery Status
The battery is evaluated by the Windows service "SigmatekUpsMonitor" when the main
supply is turned off. The status "Battery must be exchanged" can then be read via the
Named Pipe Windows service.
A battery is described as defective when the voltage, despite sufficient charging time, falls
below a specific limit with connected to a load.
Reasons:
Because of reduced capacity due to aging or improper use of the battery, the
voltage drops faster than normal when under load.
