Vertiv™ NetSure™ Control Unit (NCU) User Manual
Procedure
1. Select the power split mode (enabled or disabled). Click on SET.
Low Voltage Disconnect Functions
If low voltage disconnect functions are to be used in a power split configuration, they must be implemented in the existing power
system and signals from its control unit must be connected to the NCU.
1. For LVD1, LVD2, and/or LVD3; click on the “Modify” button and select the NCU digital inputs connected to the low voltage
disconnect control circuits.
- Set “Equipment” to the NCU device connected to the existing power system low voltage disconnect control circuit.
- Set “Signal Type” to “Sample”.
- Set “Signal” to the digital input on the NCU device selected in “Equipment” above connected to the existing power
system low voltage disconnect control circuit.
Battery Test Function
If the battery test function is to be used in a power split configuration, battery test must be implemented in the existing power system
and a test signal from its control unit must be connected to the NCU.
1. For BATTERY_TEST, click on the “Modify” button and select the NCU digital input connected to the existing systems battery
test control circuit.
- Set “Equipment” to the NCU device connected to the existing power system battery test control circuit.
- Set “Signal Type” to “Sample”.
- Set “Signal” to the digital input on the NCU device selected in “Equipment” above connected to the existing power
system battery test control circuit.
Equalize Charge Function
If the equalize charge function is to be used in a power split configuration, equalize charge must be implemented in the existing power
system and an equalizing signal from its control unit must be connected to the NCU.
1. For EQUALIZE_CHARGE, click on the “Modify” button and select the NCU digital input connected to the existing systems
equalize control circuit.
- Set “Equipment” to the NCU device connected to the existing power system equalize control circuit.
- Set “Signal Type” to “Sample”.
- Set “Signal” to the digital input on the NCU device selected in “Equipment” above connected to the existing power
system equalize control circuit.
