SITOP UPS1600 / UPS1100

24 Operating Instructions, 05.2014, C98130-A7628-A1-4-7629

Start from the battery (pin 14)

The start from the battery is initiated by closing the contact pin 14 to ground (pin 10). This

jumper must not provide a permanent connection, but must be controlled using a button. The

input is designed so that a single lamp with a permissible supply voltage of between 12 and

30 V and 8 to 15 mA can be switched in series to the switching contact. If while pressing the

button, the UPS1600 enters buffer mode, the set buffer time will be started. For example, if

5 minutes is set, the UPS1600 sets itself off after 5 minutes. If the input voltage returns

during the buffer time, the UPS1600 switches to normal operation.

If the input voltage is available, the DC UPS starts in the normal operation.

If the UPS1600 is switched-off remotely via the interface (also possible when input voltage is

available), start from the battery can be used to restart the UPS1600.

Charge current setting (pin 10 / 11 / 12)

For uncoded batteries, the size of the charge current can be changed by placing jumpers

between the terminals X2.10 (ground) and X2.11 or X2.12.
