consumption larger than 240VA, please observe that:
-
the device is set up, installed and operated in a room or enclosure marked with
“RESTRICTED ACCESS” if there are no safety messages on the device itself
such as safety signs or labels.
-
no cables or parts without insulation in electrical circuits with dangerous voltage or
power should be touched directly or indirectly
-
a reliable protective earthing connection is provided

a suitable, easily accessible disconnecting device is used in the application (e.g.
overcurrent protective device) if the device itself cannot be disconnected
-
a disconnect device, if provided in or as part of the equipment, shall disconnect
both poles simultaneously
-
interconnecting power circuits of different devices cause no electrical hazards
•
A sufficient dimensioning of the power cable wires must be selected – according to the
maximum electrical specifications on the product label – as stipulated by EN60950-1
or EN60204 or UL508 regulations.
•
The devices do not generally fulfill the requirements for “centralized DC power
systems” (UL 60950-1, Annex NAB; D2) and therefore may not be connected to such
devices!
