For the DC input of the DC plug-in power units at P1 and P2, use a
nominal rating of not more than 20 A - slow-blow characteristic.
Do not use a redundant power supply at P1 and P2 simultaneously if one
of the “+” connections of P1 or P2 is grounded.
For the redundant power supply, only use voltage sources whose
negative terminal is grounded.
For the current conductors at the voltage input of the DC plug-in power
units, use a cable cross-section of at least 2.5 mm² (North America:
AWG12).
For the current conductors at the voltage input of the AC/DC plug-in
power units, use a cable cross-section of at least 1.0 mm² (North America:
AWG16).
Connect the power supply cable to the power input.
Install strain relief.
Switch on the plug-in power units to start up the device.
WARNING
This applies exclusively to device variants with a DC power supply:
FIRE HAZARD
Install a back-up fuse in both of the input voltage conductors if the negative
terminal of the voltage source power is not grounded.
Use a back-up fuse suitable for DC.
Failure to follow this instruction can result in death, serious injury, or
equipment damage.
