Two sizes of fuses (5 kV, 7.2 kV) are available within the Transient
Suppression Network (TSN) located inside the connection cabinet. The
18-pulse drive contains three TSNs.
1. Ensure there is no power to the equipment.
A T T E N T I O N A T T E N T I O N 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.
2. Fuses are held in a place with a fuse clip. To remove the fuse
pull firmly.
3. To replace the fuse, hold it in position and push firmly until the
fuse is seated within the fuse clip. Install fuses so that the rating
is visible.
