Revision History
Issue Comments
9 2013 December Corrected typos, restored Specification of Output Voltage, added weights for fan shelf and baffle,
updated figures showing converter shelf output side, updated figures showing baffle and filter holder installation,
and added section for Maintenance – Filter Cleaning.
8 2013 July Rebranding, minor reformatting, and minor updates.
7 2008 January Rebranding.
6 2007 December Clarifications: Page 5, added ‘converter shelf’ after GR487. Page 9, Dissipation clarifications. Page
10, Listed specific protector. Page 13, The return conductor of the -48V shall be terminated in the ground window,
(held at frame ground potential). Page 13, The telecommunication line cable, carrying the +/-190V between the
equipment and the primary protectors, shall be minimum 26 AWG, and rated minimum 200V. Page 13, Airflow must
be provided at a rate of 175 lfm across the entire cross section of the shelf for operation in environments up to 65 C,
when measured at the inlet of the warmest converter shelf. Page 13, For multi-shelf systems (up to 3), this equipment
has been evaluated for continuous use in ambient temperature from -40°C to 50°C when used with the QS982A
converters. Page 28, added: Otherwise all alarm cards should be left in their factory default state of address 0,0. Skip
this step if no QS941 will be present in the system. Page 28, added text and changed picture to show angle required
to remove alarm card. Page 38, Measurement from the exterior of the CPS3200U shelf to the cabinet or building
ground bus should indicate a resistance of less than 10 Ohms. Page 56, cleaned up some of the tense grammatical
errors.
Changes: Pages 7 and 9: L1 and 2 currents. Page 13, changed J1 to TB1. Page 49, Step 12 “J6” changed to “P6.”
Page 65, changed outdoor applications to 2 shelf system configurations between fan shelves. The operating
temperature section now reads:
The CPS3200U is rated to work to 65 C in stacks of two shelves in outdoor cabinets without baffles. Note: in outdoor
cabinets where the air entering the second shelf may be heated above 65C inlet temperature, additional airflow
beyond the 175 linear feet per minute is required. These cases require an engineered solution.
In Central Office environments when baffles are required for safety reasons, a three shelf system is rated to operate
in 55C environments.
5 2007 March References to multi-shelf configurations removed. Network inspection added.
4 2006 September Added transitional statements to improve flow. Added note on grounding practice for best EMI
performance to output connector pin out description. Added Ethernet present confirmation procedure.
3 2006 June Removed -190V items including rear access converter shelf. Clarified sections to support
downward airflow as standard configuration for fan tray. Corrected drawings.
2 Reformatted sections. Corrected shelf depth in reference information.
1 Draft with focus on installing Bulk fed shelves. Pictures added.
