viewing, remove the front plastic 

bezel by pulling forward evenly on 

both sides. The unit has two front 

panel overlays. Remove the outer 

overlay (used for tower installation). 

This reveals a horizontally oriented 

front panel overlay for rack mount-

ing. Snap the front bezel back into 

place.

10.Once the UPS is installed in the 

rack, the load may be connected. 

Ensure the load equipment is 

turned off; plug all loads into the 

output receptacles on the rear of the 

UPS.

11.Plug the UPS into a dedicated wall 

receptacle properly protected by a 

circuit breaker or fuse in accordance 

with national and local electrical 

codes. Use a 20 amp rated device for 

the 2700VA, 208V unit. The wall 

receptacle must be grounded.

12.Turn ON the UPS by pressing the 

ON button; then turn on the con-

nected load equipment. The UPS is now providing conditioned power to 

your equipment.

Optional Liebert external battery cabinets may be connected to the UPS to 

provide additional battery run time. External battery cabinets are designed to 

be placed all on one side of the UPS or stacked beneath the UPS. There is no 

limit to the number of external battery cabinets that can be used but each 

cabinet will increase the battery recharge time.

1. Visually inspect the external battery cabinet for freight damage. Report 

damage to the carrier and your local dealer or Liebert representative.

2. For slide rail installations, first remove the top/side fin. Top/side fin slides 

forward and then lift up to remove. Optional rack-mount handles are 

shipped with the external battery cabinet and may be installed at this time 

if desired.

3. Securing hardware and slide rails are sold separately. Please contact your 

local dealer or Liebert representative for these additional options and any 

assistance needed. Fasten the slides into position with the screws per the 

instructions included with the slide rails.

The external battery cabinet(s) are heavy (see Specifications 

section). External battery cabinets can be used in rack-mount or 

tower configuration. Take proper precautions when lifting them.
