• 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.
• A bulk output option is provided; load connections should be made in
close proximity to the power shelf.
• The main input voltage (+/-190V) shall meet UL60950-21 RFT-V
requirements. DO NOT CONNECT TO RFT-C CIRCUITS.
• 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.
• 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 are not fused in the shelf; 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.
• For applications in cabinets, huts, vaults, and central offices, the system
mounting framework must be connected to the system integrated ground
grid.
• The designed capacitance between +/-190V RFT-V conductors is 1uF and
the measured capacitance between +/-190V and earth is 1uF. DO NOT
add capacitance to the system to reach values that exceed safety limits per
the following figure:
