Power Requirements
Line Voltage Disconnect Box
Use a line disconnect box for each power supply. This disconnect box allows the operator to turn the
power supply off quickly in an emergency situation. The switch should be located on a wall near the
power supply, and should be easily accessible to the operator. The interrupt level of the switch must be
equal to or exceed the continuous rating of the fuses. Use slow-blow fuses according to the power
requirements listed below.
