12 Revision
Rev.
Description
1
Draft with focus on installing Bulk fed shelves. Pictures added
2
Reformatted sections. Corrected shelf depth in reference information
Removed -190V items including rear access converter shelf. Clarified sections to support
3
downward airflow as standard configuration for fan tray. Corrected drawings
September Added transitional statements to improve flow. Added note on grounding practice
4
for best EMI performance to output connector pin out description. Added Ether net present
confirmation procedure
5
References to multi-shelf configurations removed. Network inspection added
Clarifications: Page 5, added 'converter shelf' after GR487. Page 9, Dissipation clarifications.
Page 10, Listed specific protector. Page 13, The return conductor
terminated in the ground window, (held at frame ground potential). Page 13, The tele
communication 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
6
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.

Rebranding
8
Rebranding, minor reformatting, and minor updates
Corrected typos, restored Specification of Output Voltage, added weights for fan shelf and
9
