2.6. Access to service area and cooling system
When installed, the UPS can only be accessed from the front. All front doors have a maximum aperture
of 90°. The area must have sufficient space for installation procedures to be carried out. Access doors
must be wide enough to permit unobstructed transport of the device (chap. 2. on page 11). To allow
correct air flow for the cooling system, leave a minimum distance of 500mm between the top of the
cabinet and the ceiling of the installation area. The UPS air intake is at the front, and the air outlet is
on the top (see Fig. 4).
