Startup may be performed by the customer’s battery qualified electrical contractor for single (not parallel) UPS
installations without any accessory cabinets such as an External Battery Cabinet.
Startup and operational checks for parallel systems or installations with accessory cabinets must be performed
by an authorized Eaton Customer Service Engineer, or the warranty terms specified in Chapter 11 Warranty
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.
