1.4.2 Moving the Cabinets 

Warning 

Ensure that any lifting equipment used in moving the UPS cabinet have sufficient lifting capacity. The UPS is 

fitted with castors 

– take care to prevent movement when unbolting the equipment from its shipping pallet. 

Ensure adequate personnel and lifting aids are available when removing the shipping pallet. 

 

Ensure  that  the  UPS  weight  is  within  the  weight  loading  capacity  range  of  any  hoisting  equipment. 

See 

Table.9-3 for UPS weight.

 

UPS and optional cabinets can be handled by means of a fork lift or similar equipment. The UPS cabinet can 

also be moved by its wheels (where are present) only for short distance. 

Note:

 

Care must be taken when handling units fitted with batteries. Keep such moves to a minimum.

 

1.4.3 Distances Required for Operating 

It’s no necessary to leave free space in lateral part of the UPS. 
To permit first commissioning, the tightening of power terminals inside the UPS and all service activity, it is 

recommended to leave enough free space to enable the passage of personnel with the doors fully opened. It 

is important to leave  a  distance of 500mm  in  the  rear  side of  the  rack  to permit adequate  circulation  of  air 

coming out the unit. 

1.4.4 Front Access & Rear access 

The  UPS  system  is  designed  for  front  and  rear  access.  For  common  service  activity  and  replacement  of 

power modules is required only front access, for installation is required rear access. 

1.4.5 Final Positioning 

When  the  equipment  has  been  finally  positioned,  ensure  the  adjustable  feet  are  set  so  that  the  UPS  will 

remain stationary and stable. 

1.4.6 Installation of Adjustable Feet 

Installation  diagrams  in  Chapter  4  of  this  manual  identify  the  location  of  the  holes  in  the  base  plate  through  which  the 

equipment  can  be  bolted  to  the  floor.  If  the  UPS  is  to  be  located  on  a  raised  floor,  it  should  be  mounted  on  a  pedestal 

suitably designed to accept the UPS point loading (more than 800 kg).   

1.4.7 UPS Composition 

The UPS structure is shown in 

Fig. 1-1

. The UPS configuration is available in 

Table. 1-1
