and Trimming Instruction.

tail of the connector cover must be depressed and
the cable handle nut rotated 1/4 turn counterclock-
wise as viewed from the feeder end.

unscrewing connector nut from incoming connec-

new S19492-1 terminal to each lead.
NOTE: The cable contains three control leads. Any
two control leads can be used, provided the two
colors used are the same at both ends. The extra
lead is a spare that can be used if one of the other
leads breaks.
