User Manual, UM1M830BNA
Spec. No: 1M830BNA, 1M830DNA Code: UM1M830BNA
Model No: M830B, M830D Revision M, May 12, 2017
DC output fuse #1 is open.
Find out and eliminate the reason the fuse is
open before replacing. Check for overload
or short circuit. If the fuse was manually
removed, check with the person that
removed it before reinserting it.
DC output fuse #12 is open.
SMDU DC Fuse Alarms (SM-DU Module must be present in system)
DC output fuse #1 is open.
Find out and eliminate the reason the fuse is
open before replacing. Check for overload
or short circuit. If the fuse was manually
removed, check with the person that
removed it before reinserting it.
DC output fuse #16 is open.
SMDUP1 [2, 3, 4, 5, 6, 7, 8] DC Fuse Alarms (SM-DU+ Module must be present in system)
DC output fuse #1 is open.
Find out and eliminate the reason the fuse is
open before replacing. Check for overload
or short circuit. If the fuse was manually
removed, check with the person that
removed it before reinserting it.
DC output fuse #25 is open.
Large DU DC Distribution Unit Alarms (Large Distribution Unit must be present in system)
