4 7 Initial Startup
Startup may be performed by the customer’s qualified electrical contractor for single (not parallel) UPS
installations without any accessory cabinets.
Startup and operational checks for parallel systems or installations with accessory cabinets must be performed
by an authorised Eaton Customer Service Engineer, or the warranty terms may 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.
4 8 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.
The Installation Checklist MUST be completed prior to starting the UPS system for
the first time.
