Electrical

Maintenance of the electrical components might require the following:

Expose personnel to high voltage.

Allow personnel to come into direct contact with high voltage.

Power down the POD during the execution of the maintenance item.

You must explicitly state and acknowledge if a POD power down will be possible. If a power down is not possible, LLS inspections will be conducted and further action will be taken at your discretion.
