Power Input Terminals
The ESML3-FL2-D4 has two green screw terminal blocks (Power Input 1 & Power
Input 2) mounted on the top panel of the switch, see Figure 2.3. The power inputs
can be used independently or they can be connected to two separate external 24V
DC power supplies to provide redundancy. The red sleeved wire should be connected
to the +ve power input and the blue sleeved wire should be connected to the –ve
power input of the green male screw block terminal.
