4.2.1.2.4 Voltage Monitor (VMON)
VMON J2 Pin 11 is an output signal. VMON functions as the voltage monitor signal of the module. It reports
the sensed output voltage with a scaled voltage between 0 and 0V. D_RTN J2 Pin 7 is used for twisted pair
cabling with VMON.

4.2.1.2.5 Current Sharing Signal (ISHARE)
ISHARE J2 Pin 10 signal is used for active current sharing. Interconnecting the ISHARE signal of the modules in
a star connection activate the active current sharing circuitry. Active current sharing is required when modules
are connected in parallel. The module’s ISHARE signal and D_RTN J2 Pin 4 should be star connected. This will
reduce the introduction of DC offset and noise to the signals.
4.2.1.2.6 D_RTN
D_RTN (J2 Pin2 and Pin7) is used for twisted pair cabling of IMON and VMON signal to reduce noise pick up.
 D_RTN (J2 Pin2) is used for twisted pair cabling with IMON.
 D_RTN (J2 Pin7) is used for twisted pair cabling with VMON.
 D_RTN (J2 Pin4) is used as return ground for the ISHARE signal.
