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 nonconducting

implement, such as a 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 circuit must be disabled before working on or around

the generator or transfer switch. Turn the generator’s AUTO/

OFF/MANUAL switch to OFF. Turn the generator’s main circuit

breaker OFF. Then place a “DO NOT OPERATE” tag on the trans-

fer switch and on the generator. Remove the Negative (Neg) or

(–) battery cable.
