E600i DC Power Modules

The system requires a minimum of one load-sharing PEM to operate, but two
are recommended for redundancy. Connect the E600 PEMs to the appropriate
branch circuit protection as defined by local electrical codes.
You must provide your own cables to connect to a remote power source in your
equipment rack. Verify that your cables are:
• Rated for at least 80A service to allow for a fully loaded E600i system at low
input voltage per your local electrical codes.
• Limit voltage drop across the cable length to 0.5V or less.
Before you make the cable connections, apply a coat of anti-oxidant paste to
unplated metal contact surfaces.
File unplated 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 PEM studs.
