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.
