8. Maintenance
I. General
The UPS is virtually maintenance free: take care of proper environmental
conditions and keep air inlets-outlets free of dust.
II. Fuses
If the AC input fuse is defect, be sure it is replaced by a compatible fuse
from the same make and type.
Never short circuit batteries. When working with batteries, remove watches,
rings and other metal objects, and only use insulated tools.
III. Battery-module replacement
Battery tray removal on tower models.
This operation can be performed when the UPS is switched ON, and
plugged into AC source. Although for safety reasons NEXT UPS Systems
recommends to perform this operation when the unit is turned OFF and
unplugged from AC source.
