1.4.4 Operation Space
As UPS has no ventilation grills at either sides, no clearances are required for the sides.
To enable routine tightening of power terminations within the cabinet, it is recommended that
clearance around the front and back of the equipment should be sufficient to enable free passage of
personnel with the doors fully opened.
1.4.5 Front and Back Access
The component layout of the UPS supports front and back access for servicing, diagnosing and
repairing the UPS, thus reducing the space requirement for side access.
1.4.6 Final Positioning
When the equipment has been finally positioned, ensure the adjustable feet are set so that the UPS
will remain stationary and stable.
