This will unlock the shunt (front cover) from the housing. Using the black handle, pull the cover off the housing and store in a
clean environment for reuse.
Note:
As you are rotating the black handle down to unlock the cover, you may feel resistance at an intermediate position
at approximately 45°. At this stage, the high voltage interlock connection has been broken. Continue to rotate the black
handle to 90° to fully unlock the outer housing.
3. Two High Voltage Manual Disconnects (MSD) are on every bus. These disconnects are located on the curb side, mounted to
the battery packs. Be sure to remove both (2) MSD shunt/covers to completely disconnect the high voltage battery packs from
the bus electrical system.

WARNING!
WARNING!
The high voltage system will remain energized for 10 minutes after the MSD's have been pulled due to
capacitance.
To reinstall the MSD: push the shunt/cover firmly in place while the black locking handle is on the forward or unlocked position. When the
shunt/cover is firmly in place rotate the black locking handle rearward until the orange locking button snaps into place, locking the handle.
Pull on the shunt/cover to ensure it is securely locked into position. The 12V battery must be disconnected while the MSD is being reinstalled.
Reconnect the 12V battery last.
Note: During normal maintenance, both MSD can be left in place.

WARNING!
The high voltage system has no user serviceable parts. Do not disassemble, remove or replace high
voltage components, cables or connectors. High voltage cables are typically colored orange for easy identification.
