Recommendation
Use flexible cables and appropriate cable end sleeves.
To minimise mechanical strain between the individual
wires and the plug, the distance between jacket and plug
should be at least 30 mm.
Requirements on the power supply
•
Conformity:
- Class PS2 acc. to IEC 62368-1
or
- Limited Power Source (LPS) acc. to IEC 60950-1
- For devices with UL-Certification: NEC Class 2
Informations on using the device acc. to UL certification (Underwriter Laboratories, USA):
•
The external circuits intended to be connected to this device shall be separated from the mains
supply or hazardous live voltage by reinforced or double insulation and meet the requirements
of SELV/PELV-Limited Energy (IEC 61010-1, clause 9.4) or Class PS2 acc. to IEC 62368-1 or
LPS acc. to IEC 60950 or Class 2 acc. to NEC.
•
In order to connect the power supply: Only use copper conductors with UL certified wire
