[X9] Power supply
Warning
Electric shock from voltage sources without safeguarding
For the electrical power supply, use only PELV circuits in accordance with IEC
60204-1 (Protective Extra-Low Voltage, PELV)
Also observe the general requirements for PELV circuits IEC 60204-1.
Use only voltage sources which guarantee reliable electrical isolation of the operat
ing and load voltage in accordance with IEC 60204-1.
Caution
Risk of burning through heating of device in the event of a connection fault.
Pay attention to the correct pin numbers corresponding to the plug location [X9] on
the device.
Do
not
connect up Pin 1 and Pin 2.
Note
Damage to the device caused by overvoltage
The inputs for the power supply do not have any protection against overvoltage.
Comply with permitted voltage tolerance.
