To avoid serious injury follow all warnings and instructions in the manual. Wear appropriate personal protective equipment.

  • Verify power supply voltage is 24 VDC.  
  • If voltage is low, disconnect the power lines and re-check voltage readings.  
  • If voltage is still low, replace power supply.  
  • If voltage is correct after disconnecting the power lines, connect items one at a time until the voltage drops to isolate the bad module.
