ATTENTION: To prevent electrical shock, ensure the main power has
been disconnected before working on the drive. Verify that all circuits
are voltage free using a hot stick or appropriate voltage-measuring
device. Failure to do so may result in injury or death.

IMPORTANT

Make sure to replace the fuse with another of the same rating. (See
