Engine Start
Control Connections
Engine-start control wires connect to control terminals
beside the Entelli-Switch 250. Engine start terminals are
indicated by a schematic symbol (the symbol indicates
the contact state for a de-energized normal source).
Figure 2 shows the engine-start contacts.
Make all other necessary control connections to the
control panel terminal blocks per the schematics
supplied with the A
TS.
NOTE: All control wires (18-12 AWG) must be
torqued to 19 in/lbs.
