Introduction

Congratulations on purchasing your APC Universal Transfer Switch (UTS). Three universal transfer

switches are covered in this manual, the UTS6, UTS6BI and the UTS10BI. A transfer switch is the key to

safe and convenient operation of portable generators for standby power. By isolating those circuits that are

using generator power, a transfer switch eliminates the risk of backfeeding the electrical utility, which can

cause injury and possibly death to utility workers, as well as property damage.

These units are fully automatic, and provide power to up to ten circuits in your home or business. Backup

power is derived from one or two independent backup sources such as a generator, uninterruptible power

supply (UPS), solar inverter, or other alternative energy source. The UTS10BI, the largest of the three

units, is shown in Figure 1-1 on the following page.

Major topics that are covered in this chapter include:

• Recommended Safety Precautions

• Unit Power Capacities

• Major UTS Features

• UTS Controls and Indicators

• UTS Power Connectors
