Initial Startup
Startup and operational checks must be performed by an authorized Eaton Customer
Service Engineer, or the warranty terms specified on page W-1 become void. This
service is offered as part of the sales contract for the UPS. Contact an Eaton service
representative in advance (usually a two-week notice is required) to reserve a
preferred startup date.

Completing the Installation Checklist
The final step in installing the UPS system is completing the following Installation
Checklist. This checklist ensures that you have completely installed all hardware,
cables, and other equipment. Complete all items listed on the checklist to ensure a
smooth installation. Make a copy of the Installation Checklist before filling it out, and
retain the original.
After the installation is complete, an Eaton Customer Service Engineer must verify the
operation of the UPS system and commission it to support the critical load. The
service representative cannot perform any installation tasks other than verifying
software and operating setup parameters. Service personnel may request a copy of
the completed Installation Checklist to verify all applicable equipment installations
have been completed.
NOTE
The Installation Checklist MUST be completed prior to starting the UPS system for the first time.
