Cable and Connector Requirements

You must provide your own cables to connect to a remote power source (for example, a circuit breaker panel) in your equipment rack or office. Cables must be sized to meet the following criteria:

•rated for at least 150A service to allow for a fully loaded E1200i DC system at low input voltage per your local electrical codes

•limits voltage drop across the cable length to 0.5V or less

Before you make the cable connections, apply a coat of antioxidant paste to un-plated metal contact surfaces. File un-plated connectors, braided straps, and bus bars to a shiny finish. It is not necessary to file and coat tinned connectors or other plated connection surfaces, such as on the E1200i DC PEM studs.

Installing DC PEMs

Each E1200i DC system requires at least one load-sharing DC PEM to operate. Two units are recommended for full facility redundancy.
