Safety Statements
Please read and follow all safety instructions and warnings before installing, maintaining, or repairing the CPS3200U
System:
• The CPS3200U platform is Underwriters Laboratories (UL) Listed per UL60950-21.
• CPS3200U shelves have high, current limited, voltages on the output connectors with ground fault protection.
• For the product to be safe the chassis must be grounded by a permanent means.
• The return conductor of the -48V shall be terminated in the ground window, (held at frame ground potential).
• Install only in restricted access areas (dedicated equipment rooms, equipment closets, or the like) in accordance
with articles 110-16, 110-17, and 110-18 of the U.S. National Electric Code (NEC), ANSI/NFPA No. 70, and
pursuant to applicable local codes.
• The telecommunication line cable, carrying the +/-190V inside the cabinet between the equipment and the
primary protectors, shall be minimum 26 AWG, and rated minimum 200V. Consideration shall be taken at the
time of installation to verify cable rating.
• Primary protection must be provided on all the telecommunication line cable consistent with UL 497.
• 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.
• This equipment is to be used in controlled environments (an area where the humidity is maintained at levels that
cannot cause condensation on the equipment, the contaminating dust is controlled, and the steady-state
ambient temperature is within the range specified).
• For multi-shelf systems (up to 3), this equipment has been evaluated for continuous use in central office
environments with ambient temperatures from -40°C to 50°C when used with the QS982A converters. For multi-
shelf systems (up to 2), this equipment has been evaluated for continuous use in outside plant cabinet, CEV, and
hut applications with ambient temperatures from -40°C to +75°C. Proper airflow is required in all cases to ensure
maximum performance.
• This equipment must not be installed over combustible surfaces.
• For installations in the United States, Listed compression connectors are to be used to terminate Listed field-
wired conductors where required. For all installations, the appropriate connector is to be applied only to the
correct size conductor as specified by the connector manufacturer, using only the connector manufacturer's
recommended tooling or tooling approved for that connector.
• If the proper connector for the country of installation is not provided, obtain appropriate connectors and follow
manufacturer’s requirements and all local requirements for proper connections. All national and local rules and
regulations should be followed when making field connections.
• The subject product is not provided with a dc mains disconnect. Provision for mains disconnect such as branch
circuit breakers shall be provided by the end product installation.
• The main output voltage (+/-190V) meets UL60950-21RFT-V requirements. DO NOT CONNECT TO RFT-C
CIRCUITS.
• Insulation on field-wired conductors should be rated no less than 90° Celsius. Wire conductor size should be
sized per electrical codes for 75° Celsius wire, and based on the ampacity of the associated protection device.
Wiring internal to enclosed equipment cabinets should be rated at 105° Celsius (minimum).
• Torque electrical connections to the values specified on labels or in the product documentation.
• Input cables must be dressed to avoid damage to the conductors (caused by routing around sharp edges or
routing in areas where wires could get pinched) and undue stress on the connectors.
• Alarm contacts on the office alarm connector (TB1) are not fused within the distribution panel; therefore, current
limiting protection for these contacts must be provided by external circuits. Maximum ratings for alarm
