Note:
The wires are identified as L (live wire), N (null wire), and E (grounding wire).
2. Tighten the screws to prevent the power supply cable from coming loose, and cover the power
supply interface set.
3. Insert the wiring terminal of the installed power supply cable into the main power supply input
port of the DCS, and tighten the screws at both ends.
4. Insert the other end of the power supply cable into the main power supply equipment.
Connecting the Standby Power Supply Cable
Connect one end of the prepared standby power supply cable to the DCS standby power supply
input port, and the other end of the cable to the emergency power supply (such as the fire alarm
system power supply). The power supply cable must support DC 24V. Pay special attention to the
connections of the positive and negative poles of the power supply. Refer to Figure 25.
