Wait at least 5 minutes after turning off the power switch and disconnecting the power cord from the wall
outlet before opening the face plate of the control box. Touching areas where high voltages are present can
result in severe injury.
The ON/OFF positions of the DIP switches inside the control box are checked only once when the power is turned
on.
