Terminal Block Wiring
Refer to the following table for information on pin functions. Locate the green
terminal blocks on the back of the spark tester and its companion green
terminal block connectors that came with the unit.
Conductors connecting auxiliary equipment, relays and switches should be
shielded 22 gauge or larger and should be stripped back ¼” (6mm) and fed into
the green terminal block connector at the proper pin number. Shields from con-
ductors connecting auxiliary equipment should be grounded to the safety
ground terminal.
