Operation Manual Universal Transfer Switch UTS6 UTS6H UTS6BI UTS10BI bu154a UTS10BI
Introduction About this product The APC® by Schneider Electric Universal Transfer Switch (UTS) is a fully automatic transfer switch for use in optional standby systems in homes or small businesses. This unit provides safe, convenient power for up to ten circuits in the home or office. Power is derived from one or two independent backup sources. Backup sources being a generator, an uninterruptible power supply (UPS), a solar inverter, or another alternative energy source.
Safety and Regulatory Information - save this information Read the Operation Manual before operating the UTS. Read, understand, and follow the Safety Precautions in this manual. Safety Precautions • Adhere to all national and local electrical codes when installing, configuring and operating the UTS. • Installation of the UTS must be performed by a qualified electrician.
UTS Configurable Features Feature Description Uninterruptible Power Supply • provides UPS backup for uninterrupted operation • provides backup power until the generator comes on line Adaptive Load Management (ALM) Provides automatic shut off (referred to as load shedding), of select circuits during blackout conditions • prevents power surges and overload conditions from stalling a generator, or tripping circuits • increases generator efficiency by 20% or more during prolonged power outages • automatica
UTS Controls and Indicators bu163a The UTS controls and indicators are located on the front of the UTS.

UTS Power Connectors The power connectors are located on the front of the UTS.
System Status Verification The UTS system status and the status of up to three power sources can be viewed by pressing the System Status button located on the front of the UTS. To navigate through the system status menus, press the System Status button after viewing the information on the LCD. LCD displays the input voltages from the UTILITY through the main load center for PHASE1 and PHASE2.
System Configuration and Setup Once the UTS has been installed and connected to utility power by a qualified electrician, the UTS is ready for configuration and setup. System setup Press the System Setup button located on the front of the UTS to enter system setup mode and to navigate through the system setup options. Use the down/up arrow buttons to navigate through the configuration options and to change values displayed on the LCD.
Time Management Use the up arrow key to select On indicating that time management is enabled or Off to disable time management. Time management is used with load shedding to ensure loads receive adequate power over extended periods of time. TIME MANAGEMENT: ON Time Management must be enabled for each circuit to be set individually for specific maximum time off and minimum time on. Refer to Circuit Maximum Time Off and Minimum Time On section in this manual.
Generator Start Mode For generators featuring manual start, use the MANUAL setting. Press the down or up arrow key to change to AUTO setting. A warning message appears on the LCD. Wait a few seconds and another message appears on the LCD asking for confirmation that the generator is located outdoors. Use the down or up arrow keys to select YES or NO. A UTS Hardwire Interface Kit for connecting the generator outside the house is available through your dealer or APC, www.apc.com.
UPS Power Rating Once the BACKUP2 SOURCE TYPE has been selected, that source type will appear in the power rating display message. Use the down/up arrow keys to set the correct power rating for the backup2 power source connected to the UTS. UPS POWER RATING: 0-1800 WATTS There are three levels for rapid rating increment changes. Press and hold the down or up arrow key to adjust the power rating and to move through the three levels described here.
Circuit setup options Setup Option 1-Circuit Load Type A UTS can be configured for many load types. These and other load types may be labeled on the building circuit breaker panel.

Circuit Maximum Time Off and Minimum Time On This setup option requires that Load Shedding and Time Management under System Setup, be set to ON. Once Load Shedding and Time Management have been enabled each circuit can be set individually for specific maximum time off and minimum time on. These settings will depend on the requirements of the load each circuit supports. Maximum Off controls the allowable time for a load to be without power, after being shed during ALM operation.
Troubleshooting Use this chart to solve minor UTS problems. Refer to www.apc.com for assistance with complex UTS problems. Problem and Possible Cause Solution Problem: While operating on utility power the UTS repeatedly drops some connected loads Cause: One or more circuits may be in Security Mode. Using the Circuit Setup button on the UTS, check to verify the status of Security Mode. Cause: The LCD displays a message indicating that one or more circuits may be experiencing an overload condition.
Problem and Possible Cause Solution Problem: While operating on backup power the UPS repeatedly experiences an overload condition causing the circuit breaker to trip Cause: The UPS power rating is set too high causing an overload condition. Refer to System Setup: Backup2 Power Rating in this manual. Cause: The UPS Surge Overload Delay Time is set too high. Refer to System Setup: UPS Surge Overload Delay Time in this manual. Cause: The UPS is experiencing a low battery condition.
