3.13 UPS Installation for Parallel Systems

WARNING: Installation and wiring must be performed in accordance with local codes/regulations

andinstalledusingthefollowinginstructionsbyaqualiedelectricalservicetechnicianonly.

Cabinet Installation

Connect the UPS for parallel installation per the diagram in Figure 3-17.

Figure 3-17: Connections for Parallel Installation

Ensure each UPS input breaker is in “o” position and there is no output from any connected UPS. Battery groups can be

connected separately or in parallel, which means the system itself provides both separate battery and common battery.

WARNING!

Make sure the N, L1, L2 and L3 lines are correct and grounding is well connected.

1. Parallel conguration supports up to six UPS systems. Do not attempt to link more than six UPS systems via parallel

conguration.

2. Install and wire the UPS system according to section 3.13.1 and 3.13.2 guidelines.

3. When installing the parallel system, the length of input wires (L1, L2, L3, N) in one UPS must be equal to the input

wires of the other UPS. Likewise, the length of output wires (L1, L2, L3, N) must also be in equal length. If not, it will

cause unbalance current on the output load.

4. Connect the input wiring of each UPS to an input breaker.

5. Connect all input breaker wiring to a main input breaker.

6. Connect the output wiring of each UPS to an output breaker.

7. Connect all output breakers to a main output breaker. This main output breaker will directly connect to the loads.

8. If an external battery pack is used, each UPS must be connected to an independent battery pack or a common

battery pack.

9. Refer to the following wiring diagram for parallel installation:
