5.1 About UPS system installation
The operator has to supply the wiring to connect the UPS to the local power
source. The installation of the UPS must be made by a locally qualified
electrician. The electrical installation procedure is described in the following
section. The installation inspection and the initial start-up of the UPS and
installing an extra battery cabinet must be carried out by an authorized Eaton
Customer Service Engineer or by other qualified service personnel authorized by
Eaton.
CAUTION
To avoid physical injury or death, or damage to the UPS or the load
equipment, follow these instructions during the UPS system installation.
CAUTION
In case of condensed moisture inside the UPS cabinet, dry the cabinet
with a blower before starting up the system.

wiring can be routed through the rear, bottom, or top of the cabinet, with
