Vertiv Liebert APM2 - Clearance; Cable Access Mode

3.7.3 Clearance
Because the UPS has no grille at the two sides, there is no special clearance requirement on the two sides.
Besides the local regulations, to enable routine tightening of the power terminals within the UPS, it is recommended that
clearance around the front of the UPS should be enough to enable free passage of personnel with the door fully open.
Meanwhile, maintain at the back of the cabinet a clearance at least 200 mm to permit adequate circulation of air coming out of
the UPS.
3.7.4 Cable access mode
The Vertiv™ Liebert® APM2 UPS uses the bottom cable access method. Refer to Power cable connection steps on page37
and Signal cable connection steps on page51 for more information.
NOTE: For Liebert® APM2 (120 kVA 400 V CE) side cable needs to be added for top cable access method.
