4.2

  PDUAC3U Series power distribution units (PDU) are CE marked to indicate 

conformance to the European Union’s Low Voltage Directive.

4.3

  These PDUs operate at voltages that could potentially be hazardous.  

Furthermore, inadvertent short circuiting by mis-connection or other error 

could be harmful.  This product should be handled, tested and installed only 

by qualified technical persons who are trained in the use of power systems 

and are well aware of the hazards involved.

The internal voltages may be at hazardous potentials.  The top cover should 

not be removed.  There are no user-serviceable components in these units. 

 

Removing the top cover will void the warranty.
