4.3. Power Supply Connections
Use an optional AD-011 or AD-031B DC Power Supply Panel to this terminal. Select the appropriate panel
taking into consideration the total current consumption of all equipment to be connected to the power supply
unit.
4.3.1. Connection for Example 1
Connect each 2 power supply units to the SX-2000CI and SX-2000CO separately as follows. Connect one
power supply unit to A channel of the DC power input terminal and the other power supply unit to the B
channel of the DC power input terminal on the SX-2000CI. Connect the power supply units to the SX-2000CO
in the same manner.
Even if one of the 2 units fails or its power supply line is broken, power is still supplied from the other unit,
preventing the system from going down.
