Connecting the DCS and the NRI Main and Standby Power Supply Cables
Connecting AC Power Supply Cables
The AC power interfaces of the X-NRI use phoenix sockets. The main power supply cables are
equipped when leaving the factory, but manually connecting AC power to the device is also
needed under some circumstances. Here are the steps:
1. Strip off the wire jacket of one end of the AC power supply cable by 20mm and connect the
cable to the main power supply wiring terminal, as shown in Figure 24.
Figure 24 Schematic Diagram of Connection of the AC Power Supply Cables
Caution!
When wiring the power cables to the socket, please pay special attention to the polarity of the
cables, they should comply with the polarity of the device. The wires are identified as L (Live wire),
N (Neutral wire), and E (Earth 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 AC power supply input
port of the X-NRI or amplifier, and tighten the screws at both ends.
4. Insert the other end of the power supply cable into the main power supply equipment.
A standard socket is used in the X-DCS3000 AC power supply, and you can insert the power
cables into the device and power ports directly.
Connecting the DC Power Supply Cables
A 24V power supply is used as the standby power for the DCS and the NRI. Connect one end of
prepared standby power cable to the standby power input ports of the DCS or the NRI, and the
other end to the standby power supply. DC 24V of voltage is required, and pay attention to
connecting the right polarity.
