Observe the following guidelines when installing DC-bus cable:
• Use only unshielded cable for DC-bus voltage
• Use 1000V rated insulation cable in this application
• Make the DC+ and DC- cable distance as short as possible to help reduce
cable inductance
• Twisting the DC-bus cable together is not required, but we recommend
twisting to make sure the DC cables are routed close to each other
• The maximum Bus Voltage Set Point reduces linearly from 750V DC to
715V DC as the DC-bus cable length per cluster increases from 0 to 70 m
(230 ft) respectively
• To prevent nuisance bus-overvoltage faults, the maximum Bus Voltage
Set Point reduces linearly from 750V DC to 715V DC as the DC-bus cable
length per cluster increases from 0 to 70 m (230 ft) respectively.
