1. Disconnect power from the DL50.
Disconnect power before servicing. Failure to follow this
warning could result in electrical shock.
ATTENTION:
!
2. Loosen the screws securing the front cover latches of the DL50. There are
6 door latches on the small displays (Catalog No. 2706-F11J, -F11JC) and
10 latches on the large display (Catalog No. 2706-F21J, -F21JC).
Note: Do not completely remove the screws securing the latches.
Loosening the screws allows the latches around the door to move freely
but still keep the door secured
The next step allows the front cover to open downward. Make
sure there is adequate clearance. Failure to provide proper
clearance may cause damage to the display.
ATTENTION:
!
3. Carefully turn the latches away from the door. After all of the latches
have been turned, the front cover can be lowered.
4. If possible, determine why the fuse has blown. Do not replace the fuse
until the fault for the fuse blowing has been corrected.
