UPS module
①
Control contact "ON"

Control contact "START"
③
"READY" signaling contact
④
"BUF" signaling contact
⑤
"OK" signaling contact
Using control contact "ON" (terminals "X1" and "X2",
①
), the buffer mode of the UPS
module can be deactivated if the power supply (line voltage) is scheduled to be shut down
(e.g. maintenance, pause, end of work/end of shift). This avoids unnecessarily discharging
the battery module.
Deactivation via the control contact is effective for all of the buffer components in the system.
Control contact ON
①
Explanation
X1-X2 closed
< 10
Ω
(Delivery state: via wire jumper)
Buffer mode of the UPS module enabled.
System is buffered when the power fails.
X1-X2 open
> 1
MΩ
All of the buffer components in the system deactivated.
The system is not buffered when the power fails.
Using control contact "START" (terminals "X3" and "X4",
②
), when the power supply voltage
(line voltage) is missing, the power supply system can be started using the energy saved in
the battery module (island operation).
Control contact START
②
Explanation
X3-X4 closed
< 10
Ω
The power supply system is started from the battery module.
X1-X2 open
> 1
MΩ
(Delivery state)
Starting from the battery module deactivated.
The signaling contact sufficient buffer readiness "READY" is in the form of a relay contact
(NO contact, terminals "13" and "14",
③
) - and signals that the buffer module is charged to x
% (factory setting: 85 %) and is therefore ready for buffering. The threshold value can be
freely parameterized via the Industrial Ethernet/PROFINET interface.
