NOTICE

IF A TRANSFER SWITCH WITH ANY TYPE OF ELECTRICAL OPERAT- ING CAPABILITIES IS TO BE OPERATED MANUALLY UTILIZING THE MANUAL OPERATING HANDLE, IT IS STRONGLY RECOMMENDED THAT THE TRANSFER CONTROL CIRCUIT FIRST BE ISOLATED. THIS IS ACCOMPLISHED BY DISCONNECTING THE S7/P7 PLUG ON THE TRANSFORMER PANEL. AN AUTOMATIC ENGINE START WILL OCCUR UNLESS THE GENERATOR RUN SWITCH SET TO “OFF.” IF,

HOWEVER, A TRANSFER SWITCH IS SUPPLIED WITH A FOUR-POSI- TION SELECTOR SWITCH (OPTION 6H), IT CAN BE TURNED TO THE OFF POSITION, MAKING IT UNNECESSARY TO UNPLUG THE LOGIC. IN THE CASE OF THE ATS DESIGN, ANY ATTEMPT TO OPERATE THE MANUAL HANDLE WITHOUT FIRST ISOLATING THE CONTROL CIRCUIT CAUSES AN AUTOMATIC TRANSFER.
