ATTENTION 
  Cable power is limited to 24 Amps per module at 60C (140 degrees F) and 32 Amps at 54C 
(129 degrees F). 
  As shown in the schematic, each switch is SPST and opens and closes one lead of the relay 
wiring. If your application requires opening and closing both sides of the load wiring, then an 
external DPST switch is required.
