•Remove all jewelry (such as rings, watches, bracelets, etc.) before working on this equipment.

•If work must be done on this equipment while standing on metal or concrete, place insulative mats over a dry wood platform. Work on this equipment only while standing on such insulative mats.

•Never work on this equipment while physically or mentally fatigued.

•Keep the transfer switch enclosure door closed and bolted at all times. Only qualified personnel should be permitted access to the switch interior.

•In case of an accident caused by electric shock, immediately shut down the source of electrical power. If this is not possible, attempt to free the victim from the live conductor but AVOID DIRECT CONTACT WITH THE VICTIM. Use a nonconduct- ing implement, such as a dry rope or board, to free the victim from the live conductor. If the victim is unconscious, apply first aid and get immediate medical help.

•When an automatic transfer switch is installed for a standby generator set, the generator engine may crank and start at any time without warning. To avoid possible injury that might be caused by such sudden start-ups, the system’s automatic start cir- cuit must be disabled before working on or around the generator or transfer switch. Then place a “DO NOT OPERATE” tag on the transfer switch and on the generator. Remove the Negative (Neg) or (–) bat- tery cable.
