Installation
Installation
Refer to instructions below for information on how to install the UPS in a rack, in a tower configuration, or
when installing the UPS with optional battery pack(s). Once the UPS has been placed in the desired tower or
rack location, complete the remaining installation steps in sequential order, beginning with “Connect
Equipment to the UPS” on page 4.
To Install the UPS in a Rack
See the installation sheet supplied with the optional rail kit (SURTRK2) to install the UPS in the rack. It is
recommended that you remove the battery before attempting to install it in the rack. See “To Install a
Replacement Battery” on page 12 for the procedure.
To Install the UPS in a Tower Configuration
For stability, the UPS is shipped with stabilizing feet. Using the UPS in a tower configuration without
the feet may result in bodily injury or equipment damage.
To Install the UPS with External Battery Pack(s)
In addition to the UPS, if your configuration includes optional Smart-UPS RT battery pack(s)
(SURT192XLBP, SURT192XLBPJ), see the battery pack user manual to complete the physical installation
for the UPS with external battery pack(s).
The UPS must be installed above external battery pack(s) when in a rack. When installing the UPS in a
tower configuration, battery pack(s) must be installed to the right of the UPS when facing the front of the
UPS. Failure to follow these instructions could result in cabling shortage.

power circuits. See step 1 on page 5 for procedure.
