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
1. Remove the Voltage Sensing Board input and output cables.
2. Remove the eight nylon nuts to remove the Insulation Board from the
cabinet side sheet.
Figure 27 - Remove the Insulation 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.
