ELECTRICAL SYMBOLS PER E1537 CONNECTORS VIEWED FROM INSERTION END

N.A. JUMPER PLUG MUST BE INSTALLED IF REMOTE KIT IS NOT PRESENT.

N.B. CONNECTIONS AS VIEWED FROM BACK OF RHEOSTAT AND SWITCHES.

N.D. ITEM FACTORY INSTALLED ON SOME MODELS AND OPTIONAL EQUIPMENT ON SOME MODELS. N.E. CONTACTOR CAN BE INSTALLED IN UNITS WITH AN L12253-1 CONTROL PC BOARD.

N.F. WHEN A CONTACTOR IS NOT USED, THE '67' LEAD TO THE POLARITY SWITCH COMES FROM THE CONDUCTOR BLOCK AND THE INPUT CABLE CONNECTS DIRECTLY TO THE CONDUCTOR BLOCK.

N.G. IF TIMER KIT IS NOT INSTALLED:

-ON UNITS WITHOUT REMOTE PC BOARD, JUMPER MUST BE INSTALLED IN J11.

-ON UNITS WITH REMOTE PC BOARD, JUMPER MUST BE INSTALLED IN J6 OF REMOTE PC BOARD. N.H. TIMER KIT HARNESS INSTALLATION:

-ON UNITS WITH REMOTE PC BOARD, TIMER HARNESS MUST PLUG INTO J6 OF REMOTE PC BOARD.

-ON UNITS WITHOUT REMOTE PC BOARD, TIMER HARNESS MUST PLUG INTO J11.

N.J. PROVIDES AN ESD PATHWAY FROM EXPOSED METAL SURFACES TO WORK.

N.K. PRESENT ON EUROPEAN MODELS ONLY.

N.L. CONNECTS TO BUSHING OF COMPONENT.
