5.6. Output
All devices that must be supplied without interruption
in the event of a supply voltage failure
("Buffered Load"), are connected to the "" and
"Output -" terminal blocks of the DC output (Fig. 08). It
is recommended that all other loads, which do not
require buffering ("Unbuffered Load"), are connected to
the 24 V DC output of the power supply.
This increases the buffer time, as this time depends
on the output current (see Fig. 10). The internal diode
ensures that the buffered loads are isolated from the
unbuffered loads.
5.7. Battery Module
The battery module is connected to the
QUINT-DC-UPS via the "B" and "Battery -"
terminal blocks. To interrupt the charge/discharge
current of the battery module, the "Battery module
selection" selector switch
$
must be set to "Service".
The fuse on the battery module
must be removed when installing or
replacing the battery module.
The QUINT-DC-UPS is optimized for use with
QUINT-BAT/24DC type battery modules.
The following battery modules are recommended:
QUINT-BAT/24DC/3,4AH (Order No. 2866349)
QUINT-BAT/24DC/7,2AH (Order No. 2866352)
QUINT-BAT/24DC/12AH (Order No. 2866365)
When using QUINT-BAT/24DC/3,4AH, the maximum
output current of 25 A must not be exceeded.
Following successful installation, the capacity of the
connected battery module must be selected using the
"Battery module selection" rotary switch
$
.
5.8. Signaling Outputs
The signal outputs are connected via terminal blocks
11/12/13
4
, 21/22/23
5
or 31/32/33
6
. The contacts
are
fl
oating contacts. The plug-in bridge provided can
be used to 24 V to grouped contacts 11,21,31.
This means that N/C contacts 12,22,32 and N/O
contacts 13,23,33 can be evaluated as switching
outputs with 0 V and +24 V voltage levels.
