YR2.DIODE Decoupling Module Instruction Manual
Recommendations for
(1) Use separate input fuse for each power supply.
redundant applications
:
(2) Use Three-phase power supplies to gain functional safety if one phase fails.
(3) When Single-phase power supplies are utilized connect them to different phases.
(4) It is desirable to set the output voltages of all power supplies to the same value (±0.5V) to avoid a false signal of the DC-ok signal.
(5) Use both inputs in parallel for currents above 10A.

Utilization of three 10A power supplies and two YR2.DIODE.The
DC-ok will only work properly if the adjusted output voltage of each
power supply will be reached after turning-on the input power. A
power supply operating in current limiting mode will result in a DC-
fail condition.

Buffer energy supplied from a DC-UPS or Buffer Module is not
wasted in "power branches".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 YR2.DIODE into account.

Set output voltage of power supply to 26.5Vdc minimum to avoid
that the charger current flows to the load instead of charging the
battery. Use a fuse between battery and YR2.DIODE!
