CAUTION!

Control cables must be separated from AC and DC power cables.

Parallel Board

The built-in parallel board connects two or more UPS systems in parallel, either to obtain increased system reliability or to obtain higher output power. The parallel board also ensures correct load-sharing between paralled systems.

NOTICE!

For reliability reasons, APC recommends separate battery packs in redundant/parallel conigurations.

To prepare the UPS for parallel/redundant mode, disconnect all sources of AC and DC power supply to the UPS and connect the ribbon cable from the parallel board to the main controller board (the ribbon cable is delivered with the UPS).

CAUTION!

DO NOT connect ribbon cable between controller and parallel card in single configurations.

Ribbon cable is for parallel operation only.

Complete the parallel system set-up by connecting the external control cables (see below). Follow the instructions in the “Programming Parameters for Advanced Parallel” section of this guide to execute necessary re-programming.
