Schematic design
DC UPS
The image is a schematic representation of the
design and does not contain all parts.
Observe the installation instructions.
Power supply unit
Use current-limited source (e. ? g., QUINT POWER power sup-
ply) or a suitable fuse. If loads must not be supplied in the
event of a mains breakdown or failure, they must be con-
nected directly to the output of the power supply as unbuf-
fered DC load.

Input: the input is supplied with 18 ? ? ? 30 ? V ? DC.
Output: in the event of mains interruption or failure, the
connected DC load is supplied with voltage without inter-
ruption.
Battery: the required power is made available by the pow-
er storage device. The signal cable is used for communi-
cation between the UPS and power storage device.
Signal I<I N : when connected to the I<I N output of the
QUINT POWER power supply unit, the power supply unit
is charged with the maximum charging current as quickly
as possible (fast battery charging). Supply of the buffered
DC load always has priority. This function is available
when the power supply unit makes a static power reserve
available with corresponding signal contact e. ? g., QUINT
POWER with POWER BOOST and preventive function
monitoring. Without this, charging is performed at re-
duced current.
Signal R1, R2: remote control
Power storage device
Depending on the desired buffering time, select the power
storage device listed under accessories.
VRLA power storage devices are temperature
dependent. If possible and to ensure optimum
function, install at a cool location e. ? g., at the
bottom of the control cabinet.
