26 CHAPTER 2: INSTALLING THE ADVANCED RPS CAUTION: The Type 3 DC Power Module is for installation by suitably qualified service personnel only. Refer to the Type 3 Power Module Installation Guide. CAUTION: Only use the cables designed for the power module you are installing. CAUTION: When mating the RPS connectors to the inlet and outlet sockets, take special care to ensure that the retaining spring, where fitted, locates outside the plug casing. CAUTION: If Type 3 Power Module DC cables are used, all screws must be tightened with a suitable tool. Standard DC Cables Use the standard DC cable supplied with the power module to provide power redundancy. If the power module has a protective cover over the D-type connector, remove this first and keep somewhere safe as it will need to be replaced if you remove the cable at any time. Connect one end of the cable to the power module outlet and the other end of the cable to the Redundant Power System socket on the rear of the SuperStack unit. For more information, refer to the documentation that accompanies the power module you are installing. Optional 'Y' DC Cables Refer to the Advanced RPS Type 3 Power Module Installation Guide and Advanced RPS Type 3 'Y' Cable Installation Guide. Use a DC 'Y' cable of the appropriate type (available from your supplier) to provide full redundancy (resilience). Connect one short lead to each of the two module outlets and the long lead to the Redundant Power System socket on the rear of the SuperStack unit. For more information, refer to the documentation that accompanies the power module and the 'Y' cable you are installing. CAUTION: Do not attempt to use a 'Y' cable to power two separate SuperStack units. The equipment will not operate.
