WARNING
To protect personnel against accidental contact with hazardous voltages, ensure
that the load, including connections, has no live parts which are accessible. Also
ensure that the insulation rating of the load wiring and circuitry is greater than or
equal to the maximum output voltage of the power supply.
WARNING
Wear protective gloves and use caution when removing the circular knockout
from the shield as described below. The exposed metal edges of the knockout
may be sharp.
