EMS controller installation

Install the Voltmasters EMS controller on a DIN rail: the 24V power wiring per wire colour, the ground and the network connection.

The EMS controller seen from the front with its status LEDs, network port, MAC address label and the 24V terminal wired in orange, white and green-yellow.

Connecting the controller

Wiring diagram of the EMS controller. At the bottom is terminal X4 with four screws: the orange wire from the plus of the 24 VDC power supply goes to the first terminal (24V), the white wire from the minus to the second terminal (0V), the third terminal stays free and the green-yellow earth wire goes to the fourth terminal on the right. At the top is the network port, with a network cable to the router or switch of the site. Through that router the controller connects to the internet and to the devices on the same local network.
  1. Mount the controller on the DIN rail

    Clip the controller onto a DIN rail in the cabinet.

  2. Connect power and earth

    Connect the wires to terminal X4 at the bottom: orange to 24V (+), white to 0V (−) and green-yellow to the earth on the right.

  3. Plug in the network cable

    Plug the network cable into the network port at the top.

  4. Note the Controller ID

    The Controller ID is printed on the label of the controller. You enter it when you create the project: see Adding a new project.

The same controller with the network cable plugged into the port on top and the power and ground wires in the terminal below.

The controller needs two connections:

  • Internet, for the connection with the Voltmasters platform.
  • The same local network as all devices you pair.

Which ports and domains must be reachable is explained in Internet and network.

To follow the controller on site or to set its network without the platform, open its local interface from a laptop.
