8.2.12 Output Distribution Module.
2.4.2 Moving The Cabinet
Warning
1. Ensure that any equipment used to move the UPS has sufficient lifting capacity. For the UPS weight, refer to
Table 11-3.
2. The UPS is fitted with casters. Take care to prevent the cabinet from moving when unbolting the cabinet from the
shipping pallet. Ensure that adequate personnel and lifting aids are available when removing the shipping pallet.
3. The UPS casters are just strong enough for cabinet moving on flat surface. They may not function well when you
move the cabinet on uneven surface.
4. The cabinet can be pushed forward or backward only. Pushing it sideward is not allowed. When pushing the cabinet,
take care not to overturn it as the gravity center is high.
The UPS can be moved by means of a forklift or similar equipment. It can also be moved short distances by its
casters.
2.4.3 Clearances
The UPS has no ventilation grilles at either side, therefore, no clearance is required at either side.
The component layout of the UPS supports front access and rear access in UPS service, diagnosis and repair. To
enable routine tightening of power terminations within the UPS, in addition to meeting any local regulations,
it is recommended to provide adequate clearance in the front and at the back of the cabinet for unimpeded
passage of personnel with the front and back doors fully opened.
2.4.4 Cable Entry
The UPS uses top cable entry and bottom cable entry, with cable entry holes provided both at the bottom and
on the top of the UPS.
2.4.5 Final Positioning And Fixing
When the UPS has been finally positioned, ensure that the adjustable feet are set so that the UPS will remain
stationary and stable.
2.4.6 Installing Power Module And Output Distribution Module
The installation positions of the power modules and output distribution modules are shown in Figure 2-1. If
four output distribution modules are configured, the position of the SPM monitoring module shown in
Figure 2-1 is used to install an output distribution module.
Install the power modules and output distribution modules from bottom to top to avoid cabinet toppling due
to high gravity center.
