Connect the two battery cables to the two battery packs’ connectors
respectively. For each battery cable, use the two screws and two
standoffs (provided in the package with the battery cable) to firmly fix the
battery cable on the battery pack. See
Figure 13
.

NOTE:
There are two identical external battery connectors on the
Delta external battery pack, and you may use either of the battery
connectors to connect to the UPS.
y
Parallel the Delta External Battery Packs with the 5/ 6/ 8/ 10kVA UPS
To extend the backup time, you may parallel the Delta external battery packs
before connecting them to the UPS. The Delta external battery pack has two
models, RT-6KB and RT-10KB. The two models’ parallel methods are similar.
Thus, in
Figure 14
, only the illustration of RT-6KB model is taken for example.
WARNING:
For parallel application, only use the same type of Delta external
battery packs (same material No.).
1
Use the provided battery cable (
1
) to connect each parallel Delta
external battery pack’s battery connector (
4
). Each Delta external
battery pack has two identical battery connectors; you can choose either
of them for connection. Make sure that the positive cable (+) connects to
the positive pole (+) and the negative cable (-) connects to the negative
pole (-). Use the screws (
2
) and standoffs (
3
) (provided in the
battery cable’s package) to fix the battery cable firmly on the parallel
Delta external battery packs. Please see
Figure 14
.
NOTE:
If you want to connect more than two Delta external battery
packs, follow the steps mentioned above.

After paralleling the Delta external battery packs, follow the steps
mentioned in ‘
Connect the Delta External Battery Pack with the
5/ 6/
8/ 10kVA
UPS
’ to complete the connection between the UPS and the
parallel Delta external battery packs.
y
Connect the 15/ 20kVA UPS (Single Unit) with the Parallel Delta External
Battery Packs
WARNING:
For parallel application, only use the same type of Delta external
battery packs (same material No.).
If it is not for common battery application, each 15/ 20kVA UPS must connect
to at least two external battery packs, and the number of battery packs must be
the multiple of two and only two of the battery packs need to be connected to
the 15/ 20kVA UPS. The Delta external battery pack has two models, RT-6KB
and RT-10KB. The two models’ parallel methods and UPS connection methods
are similar. Thus, in the following instructions and
Figure 15
, only one 15/
20kVA UPS connecting to four parallel Delta external battery packs (model RT-
10KB) is taken for example.
1
Each Delta external battery pack has two identical battery connectors;
you can choose either of them for the battery cable connection
mentioned below. Use the battery cable (provided in the Delta external
battery pack) to connect the 1
st
and 3
rd
parallel Delta external battery
packs’ battery connectors. Use the battery cable (provided in the Delta
external battery pack) to connect the 2
nd
and 4
th
parallel Delta external
battery packs’ battery connectors. Make sure that the positive cable (+)
connects to the positive pole (+) and the negative cable (-) connects to
the negative pole (-). Please see
Figure 15
.

After paralleling the Delta external battery packs, follow the steps
mentioned in ‘
Connect the Delta External Battery Pack with the 1
5/
20kVA
UPS
’ to complete the connection between the UPS and any two
of the parallel Delta external battery packs. Please see
Figure 15
.

Connect the 15/ 20kVA UPSs (Parallel Units) with the Delta External
Battery Packs
If it is not for common battery application, each 15/ 20kVA UPS must connect
to at least two external battery packs, and the number of battery packs must
be the multiple of two and only two of the battery packs need to be connected
to the 15/ 20kVA UPS. The Delta external battery pack has two models, RT-
6KB and RT-10KB. The two models’ parallel methods and UPS connection
methods are similar. Thus, in the following instructions and
Figure 16
, each
of the two parallel 15/ 20kVA UPSs connecting to two parallel Delta external
battery packs (model RT-10KB) is taken for example.
1
Use the two battery cables (provided in the 1
st
parallel 15/ 20kVA UPS’s
package) to connect the 1
st
parallel 15/ 20kVA UPS with its two Delta
external battery packs. Use the two battery cables (provided in the 2
nd
parallel 15/ 20kVA UPS’s package) to connect the 2
nd
parallel 15/ 20kVA
UPS with its two Delta external battery packs. Please see
Figure 16
and
cross-refer to ‘
