Power Supply

On the most current machines, voltage indicators on the Power Supply are simply blue LEDs, on or off.

For older Power Supplies, make sure the two breakers are on and check the voltage levels on the two LED readouts. There are also two green lights on the top of the Power Supply indicating incoming power.

**WARNING** Before doing any maintenance that involves removing the cover for the Power Entry or Power Supply Module, the power must be disconnected at a lockout tagout and the machine disconnected from the source of power, not just “turned off”.
