Operating Schematic (NA-4)
N.A. WHEN START P.C. BOARD IS INSTALLED, JUMPER CONNECTOR "A" IS REMOVED.
N.B. THESE LEADS ARE NOT PRESENT ON LOGIC P.C. BOARDS
WITH DIP SWITCHES.
N.C. 531-532 115VAC; 531-25 115VAC (SWITCHED) - 250 VA
N.D. 87-531 115VAC - 1/2A SWITCHED.
N.E. ON EARLIER UNITS, LEAD #689 WAS LOCATED BETWEEN #31 and #67
(FORMERLY #5), LEAD #510 WAS LOCATED BETWEEN #87 & #32, AND
LEAD #31 WAS LOCATED NEXT TO #681. CAREFULLY NOTE LEAD POSITIONS
BEFORE MAKING ANY CONNECTIONS TO TERMINAL STRIP.
N.F. JUMPER LEAD TO BE CONNECTED TO PIN "H" AT ALL TIMES.
UNIT SHIPPED WITH LEAD IN THIS POSITION.
