Siemens SITOP UPS1600 Manual page 29

This can occur if the UPS was remotely shut down via the interface.
Note
From UPS Manager Version V4.71.13 and UPS1600 Version V2.1.0, when starting from the
battery, buffer operation is identified when powering up. After the set time "Shut down PC on
power failure" the PC is correctly powered down and switched off. For earlier versions of the
UPS Manager and the UPS1600 Version, when starting from the battery after the buffer time
expires, the output of the UPS1600 is switched off without first having powered-down the
PC.
Charge current setting (pin 10 / 11 / 12)
For uncoded batteries, the size of the charge current can be changed by placing jumpers
between terminals X2.10 (-) and X2.11 or X2.12. These settings are only effective if the
"Connection threshold" rotary coding switch is not set to REN.
Table 2- 5
Remark
The charge current can be automatically reduced if the charge current plus the load current
at the UPS1600 results in an overload of the feeding power supply. The charge current can
also be reduced if the ambient temperature of the UPS1600 is higher than 40 °C - or if the
input voltage at the UPS1600 is less than 24 V.
