2.15 Grounding Checks
Perform these checks to ensure that a safe grounding system is provided.
• If a rack distribution system is being used.
– Ensure power is removed from the rack.
– Connect the Galaxy 55 power cord to the rack distribution and the enclosure.
• If a direct connection is made with the Galaxy 55 power cord, ensure that it is connected to the enclosure.
Warning Some electrical circuits could be damaged if external signal cables or power control cables are
present during the grounding checks.
• Check for continuity between the earth pin of the IEC 320 connector on one of the Power Supply/Cooling
modules and any exposed metal surface of the Galaxy 55 enclosure.
