Power Cable (with 2PIN-I Terminal Blocks)
Connection
The power cable (with 2PIN-I terminal blocks) is connected as follows:
- One end is connected to the DC power interface of the device through a 2-pin DC power terminal block.
- The other end is connected to a DC power supply device through a 2-pin DC power terminal block.
The power cable (with 2PIN-I terminal blocks) consists of 2-pin DC input terminal blocks at both ends. The 2-pin DC input terminal blocks can prevent damages to the device caused by reverse connection of the power wires. Once the positive and negative wires are reversely connected to the power terminal blocks, the device will not be powered on.
