Hazardous voltage!
Removing the filter mat while the drive is running can cause serious injury

Make sure that long, thin objects, such as wires and screwdrivers, DO
NOT enter the air intake of a medium voltage compartment. These
objects can cause FATAL short-circuits.

To prevent foreign matter from entering the air intake, DO NOT stop
work for lengthy periods.
