Power Supply | 25DC Power Entry ModulesThe system requires a minimum of one load-sharing PEM to operate, but two are recommended forredundancy. Connect the E600i PEMs to the appropriate branch circuit protection as defined by localelectrical codes.For full redundancy, each PEM must be attached to an independent power source with a dedicated circuitbreaker.Figure 6-5. DC Power Entry ModuleCable and Connector Requirements1 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 peryour local electrical codes• limit voltage drop across the cable length to 0.5V or less2 Before you make the cable connections, apply a coat of anti-oxidant paste to unplated metal contactsurfaces.3 File unplated connectors, braided straps, and bus bars to a shiny finish. It is not necessary to file andcoat tinned connectors or other plated connection surfaces, such as on the PEM studs.Install the DC PEMsTo install a DC PEM:Step Task1 Make sure that the remote power source (the circuit breaker panel) is in the OFF position.2 Make sure that the over current protector (located on the PEM front panel) is in the OFF position.48V in48V in StatusStatus-48/-60Vdc 75A-48/-60Vdc 75ACAUTION -CAUTION - Use copperUse copperconductors onlyconductors onlyCC-E600-PWR-DCVoltage LED Status LEDStudsOver Current ProtectorFinger BarrierLocking ScrewsHandle
