Type 3 (325 W) Power Module — 3C16075
This module is suitable for powering a specific range of SuperStack
units. See Appendix C for a list of these units. This module provides
+27 V through the connector. A Type 3 DC power cable is supplied
with each module.
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.
If you cannot find your SuperStack unit listed in Appendix C, consult
the User Guide that accompanied the unit for its DC power rating, or
your supplier.
Power Module Cables
There are two types of DC cable available for each power module:
■
Standard DC Cable — supplied with each power module.
Use the standard DC cable to provide power redundancy by
connecting the outlet of the power module to the Redundant
Power System socket on the rear of the SuperStack unit.
■
Optional ‘Y’ DC Cable — obtained from your supplier.
Use a DC ‘Y’ cable of the appropriate type to provide full
redundancy by connecting the two short leads to two power
module outlets and the long lead to the Redundant Power System
socket on the rear of the SuperStack unit.
CAUTION: Do not attempt to use a ‘Y’ Cable to power two separate
SuperStack units. The equipment may not operate.
Type 1 DC Cables
Use a standard DC cable, supplied with each Type 1 60 W and 100 W
Power Module, to connect a Type 1 Power Module to a SuperStack
unit.
An optional ’Y’ DC cable (3C16079) is available to connect two
Type 1 60 W or two Type 1 100 W Power Modules to a SuperStack
unit for full redundancy.
