3.5 UPS Installation for Parallel System
Warning:
Installation and wiring must be performed in accordance with the local codes/regulations and installed using the
following instructions by a qualified service technician only.
If the UPS is only for single operation, you may skip this section and proceed to
section 3.6
.
1) Parallel configuration supports up to three UPS systems. Do not attempt to link more than three UPS systems via parallel
configuration.
2) Install and wire the UPS system according to the
section 3.4
guidelines.
3) The total length of the input cable must be equal to the total length of the output cable for a parallel configuration on all units.
4) Connect the input wiring of each UPS to an input breaker. Breaker specification for SVT20KX / SVT30KX is 300V, 63A.
5) Connect the output wiring of each UPS to an output breaker. Breaker specification for SVT20KX / SVT30KX is 300V, 63A.
6) Connect all output breakers to a main output breaker. This main output breaker will directly connect to the loads.
7) If an external battery pack is used, each UPS must be connected to an independent battery pack.
Note: The parallel system cannot use a common external battery pack. This will cause permanent damage to the entire system.
8) Refer to the following wiring diagram for parallel installation:

3.6 External Battery Connection
The UPS comes with a robust internal battery system; external batteries
are needed only to extend runtime. Adding external batteries will increase
runtime and require additional recharge time. This UPS supports Tripp Lite
external battery model BP240V135*.
The illustration at right shows the location of the UPS system’s external
battery connector A where the battery pack connects. Follow the
installation instructions for your battery pack as they appear in your battery
pack Owner’s Manual. Ensure the cables are fully inserted into their
connectors. Small sparks may occur during battery connection; this is
normal.
Do not connect or disconnect battery packs when the UPS is running on
battery power.
*Limit three external battery packs per UPS.
