18.7. EXAMPLE: DECOUPLING OF BRANCHES
Buffer energy supplied from a DC-UPS or buffer module is not wasted in “power branches”.
Please note:
Set output voltage of the power supply to a level that the buffer unit or DC-UPS will not start unexpected. Take the
voltage drop of the YRM2.DIODE into account.

18.8. USE IN A TIGHTLY SEALED ENCLOSURE
When the redundancy module is installed in a tightly sealed enclosure, the temperature inside the enclosure will be
higher than outside. The inside temperature defines the ambient temperature for the redundancy module.
Results from such an installation:
Power supply is placed in the middle of the box, no other heat producer inside the box
