Tripp Lite Modular E3 Series 3-Phase UPS Systems provide a better approach to parallel connection. All models are parallel-ready, eliminating the need to differentiate between parallel and non-parallel SKUs. Tripp Lite provides everything needed for a parallel connection, including non-proprietary wall-mounted parallel distribution panels with integral system level maintenance bypass connections. Parallel communication between the Tripp Lite UPSs requires only a simple DB9 cable connection (provided with each UPS). It does not require the purchase and installation of an additional proprietary controller/distribution cabinet, like some competitors' models require.
