Rackmount Setup
CAUTION: The cabinet is heavy (74 kg/163 lb): 1) Dell strongly recommends removing the battery tray from the
UPS before lifting. 2) Lifting the cabinets into the rack requires a minimum of two people.
CAUTION: Removing the batteries should be performed or supervised by personnel knowledgeable about
batteries and the required precautions. Keep unauthorized personnel away from batteries.
Removing the Battery Retaining Bracket
1Loosen the thumbscrew on the battery retaining bracket and remove.

10 |Installation and Startup
Removing the Battery Trays
2Pull the battery trays using the plastic tabs and remove the battery trays.

Installation and Startup |
Installing the Rails
NOTE: The instructions are the same for square-hole racks and unthreaded, round-hole racks. The rails fit both
rack styles. The square-hole rack is shown in the illustrations.
3Select the proper holes in the rail for positioning the UPS in the desired location in the rack.
The rails should be located at the bottom of the 4U space allocated for the UPS or 3U for the
EBM.
4Position the end of the left and right rails labeled FRONT facing inward.

12 |Installation and Startup
5Attach the rails to the rack:
Engage the back end of the rail until it fully seats on the vertical rack flange and the hook latch
locks in place.
Pull the rail toward the front.
Push the front end of the rail until it fully seats on the vertical rack flange and the hook latch locks
in place.
Installing the Cabinet
6Slide the cabinet into the rack. Repeat for any additional cabinets.

13
Installation and Startup |
Securing the Cabinet
7Secure the front of the cabinet to the rack using the thumbscrews on the mounting brackets.
Tighten by hand; do not use power tools. Repeat for any additional cabinets.
Installing the Battery Tray
8Install the UPS battery trays.

14 |Installation and Startup
Replacing the Battery Retaining Bracket and Connecting the Internal Battery Connectors
9Replace the battery retaining bracket.
10 Tighten the thumbscrew.
Torque the screw to 0.7 Nm (6.2 lb in).
NOTE: A small amount of arcing may occur when connecting the batteries. This is normal and does not damage
the unit or present any safety concern.
11 Connect the internal battery connectors and attach to the battery retaining bracket between the
two studs.

Installation and Startup |
Installing the UPS Front Cover
12 Install the UPS front cover.
Connecting the Equipment
13 If you plan to use Dell UPS Management Software, connect your computer to the USB port using
the supplied cable.
14 If your rack has conductors for grounding or bonding of ungrounded metal parts, connect the
ground cable (not supplied) to the ground bonding screw.
15 If an emergency power-off (disconnect) switch is required by local codes, see “Installing Remote
Emergency Power-off” (REPO) in the Dell Line-Interactive Rack UPS 5600W User's Guide.
16 Plug the equipment to be protected into the UPS output receptacles, but do not turn on the
protected equipment.
NOTE: Verify that the total equipment ratings do not exceed the UPS capacity to prevent an overload alarm.

16 |Installation and Startup
Hardwiring the UPS Input
WARNING: Only qualified service personnel (such as a licensed electrician) shall perform the electrical
installation. Risk of electrical shock.
The UPS requires a dedicated branch circuit that meets the following requirements:
S5600W/208V models only: 40A 2-pole circuit breaker to provide short circuit and overcurrent
protection
S5600W/230V models only: 32A for Europe (or 35A for North America) 2-pole circuit breaker to
provide short circuit and overcurrent protection
SThe protection device requires a two-pole disconnection device between the UPS output and the
load (see Figure 4)
SThe breaker must be wall-mounted and be readily accessible to the operator
SFor Europe, the breaker must meet the IEC/EN 60934 standard and have a contact air gap of at
least 3 mm
S200–240 Vac
SSingle-phase
- 5600W/208V model is phase-to-phase
- 5600W/230V model is phase-to-neutral
