Safety
Safety Statements
Read and follow all safety instructions, warnings, and precautions in this manual and the manuals of all
equipment before installing, maintaining, or repairing the power system. Equipment manuals contain
additional safety statements, warnings, and precautions specific to the equipment.
• The H569-445 Secondary DC Power Distribution Bay is Underwriters Laboratories (UL) Listed per
Subject Letter 1801 (DC Power Distribution Centers for Telecommunications Equipment) for use
in the USA.
• Install only in restricted access areas (dedicated equipment rooms, equipment closets, or the like).
• Use this equipment in a controlled environment (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). Evaluated maximum ambient
temperature: 104°F (40°C).
• Do not install this equipment over combustible surfaces.
• Compression Connectors
• For installations in the U. S. or Canada, use Listed/Certified compression connectors to terminate
Listed/Certified field-wire conductors where required.
• For all installations, apply the appropriate connector 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.
• The field wiring connections have been evaluated for connection of minimum 90°C conductors sized
per the U.S. National Electrical Code using 75°C ampacity tables.
• Torque electrical connections to the values specified on labels or in the product documentation.
• The short circuit current capability of the battery input to the distribution panel must not exceed
10,000 amperes.
• Use only fuses and circuit breakers specified in the product documentation to avoid possible in injury
to service personnel or equipment damage. They may not be provided with the equipment.
• Size fuses and circuit breakers as required by the National Electric Code (NEC) and/or local codes.
Refer to the equipment ratings to assure current does not exceed:
• Continuous Load (List 1) - 64% of protector rating
• Maximum Load (List 2 - typically end of discharge) - 80% of protector rating.
• Field-wired Conductors - Follow all National Electric Code (NEC) and local rules and regulations when
making field connections.
• Size field-wired conductors based on listed recommendations, National Electric Code (NEC)
and/or local codes based on 70°C ampacity.
• Insulation rating (minimum): 90°C; 105°C if internal to enclosed equipment cabinets.
• Dress cables to avoid undue stress on the connectors and damage to the conductors caused by
routing around sharp edges or routing in areas where wires could get pinched.
