(1) For 8720MC-RPS065-HV2 and 8720MC-RPS190, you may have up to two slave units with a master unit. Multiply these values by the number of slave units.
(2) Use this case only when the bus capacitance exceeds the internal precharge rating. You must use the specified resistor. Calculate rated wattage and surge
resistivity for that resistor. See the 8720MC Regenerative Power Supply Installation Manual, publication 8720MC-RM001 , for configuration details.
(3) Use this case only when the bus capacitance exceeds the external resistor rating. You must use the specified resistor. Calculate rated wattage and surge
resistivity for that resistor. See the 8720MC Regenerative Power Supply Installation Manual, publication 8720MC-RM001 , for configuration details.
IMPORTANT Large levels of load capacitance may require modification of the 8720
regenerative power supply internal precharge/discharge circuit.
See the Wiring instructions in the 8720MC Regenerative Power Supply
Installation Manual, publication
8720MC-RM001 , for information on how
to determine the appropriate precharge/discharge resistance power value
(Ohms/Watt) to accommodate the capacitance of your system.
