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!
