Transient Suppression Network Fuse Replacement


Two sizes of fuses (5 kV, 7.2 kV) are available within the Transient
Suppression Network (TSN) located inside the connection cabinet.


1. Ensure there is no power to the equipment.

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,
and the rivets are not against the clips.
