Attach AC power and control wiring to the UPS. The power wires are coiled in the bottom of the PDU. There are five main input wires, four bypass input wires, and four output wires coiled on the floor of the PDU. Each set of wires is labeled. The control wires for the UPS Maintenance Bypass control board and the UPS EPO control board are also coiled in the PDU. The diagram below provides an overview of the connections that you will make between the PDU and the UPS.
