4 Safety
Safety Statements
Please read and follow all safety instructions and warnings before installing, maintaining, or repairing
the CPS6000 System:
•
The CE Mark demonstrates compliance with the European Union Council Directives for Low Voltage and EMC.
•
The CPS6000 platform is Underwriters Laboratories (UL) Listed per Subject Letter 1801, DC Power Distribution
Centers for Telecommunications Equipment.
•
CPS6000 shelves equipped with QS820A ringers (in development) have hazardous secondary voltages on the
secondary bus output connectors.
•
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.
•
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).
•
This equipment has been evaluated for continuous use in ambient temperature from - 40°C to 75°C when used with
the QS862A rectifier.
•
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 and all local requirements for proper connections. All national and local rules and regulations
should be followed when making field connections.
•
Load connections to Bulk Output Modules should be made in close proximity to the power shelf.
•
The main output voltage (48V) meets SELV requirements.
•
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.
•
Battery 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 (J1) are not fused within the distribution panel; therefore, current
limiting protection for these contacts must be provided by external circuits. Maximum ratings for alarm
connections are 60Vdc and 0.5 amperes. Exceeding these maximum ratings could result in fire or damage to the
unit.
•
Fuse and/or circuit breaker loads must not exceed 80% of the fuse and/or circuit breaker current rating. Distribute
loads across the panel.
The short circuit current capability of the battery input to the distribution panel must not exceed 10,000A.
•
•
AC branch circuits to this equipment must be protected with either fuses or circuit breakers sized as required by
the National Electric Code (NEC) and/or local codes. The maximum size of the over-current protector is based on
the type of shelf. Refer to the equipment ratings to assure rating of equipment will not exceed 80% of the value of
the protector chosen.
•
An accessible ac disconnect/protection device to remove ac power from the equipment in the event of an
emergency must be provided.
