• 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.
• High leakage currents are possible due to contribution from simultaneous multiple AC
input connections. Earth ground connection is essential before connecting the ac
source to the shelf. This connection must be achieved by ensuring that the C.O.
grounding stud is connected as shown in the Installation Section, or quality service
personnel shall ensure that the rack system is bonded per the provision below.
• In enclosed equipment cabinets, the CPS6000 mounting framework must be connected
directly to the cabinet ac service ground bus. For applications in huts, vaults, and
central offices, the CPS6000 mounting framework must be connected to the system
integrated ground grid.
• Installing fuses or circuit breakers not specified for use in these distribution modules
may result in injury to service personnel or equipment damage. Use only replacement
parts listed in this manual and on the equipment drawings.
• The telecom-type (e.g., GMT type) fuses can produce sparks during interruption or
clearing of a fault on a high energy circuit. Use only fuses provided with safety caps
for this type of circuit. Installing telecom-type fuses not equipped with safety caps
may result in injury to service personnel.
