Additional safety instructions for DC power supply circuits
To guarantee safe operation of devices with DC power supply voltages larger than 60 volts DC or a power
consumption larger than 240 VA, please observe that:
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 is not disconnectable
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 the applied safety standards.
The product does not generally fulfill the requirements for "centralized DC power systems” as stipulated by the
applied safety standards and therefore may not be connected to such devices!
