AUTOMATIC TRANSFER SWITCH
This generator must be connected to an automatic transfer switch. The automatic transfer switch detects when a power failure occurs and automatically starts the engine to provide generator power. When the utility power becomes available, the transfer switch automatically shuts down the generator and switches back to the utility power. (See figure 1 for typical installation).
Refer to the transfer switch manual for detailed installation and safety instructions. Comply with all the instructions in the manual along with the labels and tags attached to the transfer switch.
WARNING
•Hazardous "backfeed" voltage can cause severe injury or death. Install a transfer switch in standby power installations to prevent connection of standby and other sources of power. Electrical backfeed into a utility electrical system can cause serious injury or death to utility personnel working on transmission lines.
•Do not try MANUAL operation of the transfer switch until all power supplied to the switch has been positively turned OFF. Failure to turn OFF power supplied may result in extremely dangerous and possibly lethal electrical shock or arching.
