Inspect Voltage Sensing Board
The input VSB cable connections and output VSB wire connectors must be
firmly fastened and show no signs of damage or accumulation of dirt, dust, or
debris.
Replace Voltage Sensing Board

ATTENTION: To prevent electrical shock, disconnect the main power before
working on the Voltage Sensing Board. Verify that all circuits are voltage-free,
using a hot stick or appropriate high voltage-measuring device. Failure to do so
may result in injury or death.
