Choose a location

The VOOL LMC should be mounted on a DIN rail inside an electrical switchboard. Ensure the selected space can accommodate a 4P-sized device.

1. Mount the LMC on DIN Rail

Before installation, disconnect the power supply to prevent electrical hazards.

Secure the LMC on the chosen location on the DIN rail.

2. Connect Current Transformers

The LMC comes with three current transformers available in 50A, 100A, and 200A configurations. They are split-core type, meaning they don’t require disconnection of power cables for installation.

Before installing the current transformers on wires, ensure their socket is connected to the LMC.

3. Install with Previously Installed Current Transformers or Multimeter

If current transformers are in the distribution box, ensure compatibility before connecting to the LMC.

If a multimeter that supports the Modbus protocol is available on-site, it can be directly connected to the LMC.

4. Solar Installations

The LMC can connect to solar inverters that support Modbus communication protocol and have an available Ethernet connection socket.

For detailed guidance on connecting and setting up solar with LMC, please contact [email protected].

5. Connect AC Power Supply. For three phase connection connect the cables to the designated socket and connect the socket to the LMC.

6. Connect Cables to the DesignatedSocket and Socket to LMC (Single-Phase)

Switch on the LMC and ensure that green LEDs light up. If any LEDs are unlit or red, refer to the troubleshooting section.

7. Connecting LMC to chargers

Chargers can be connected to LMC via Ethernet cable using the right-side Ethernet port on the LMC or via WiFi. For Wi-Fi configuration, the chargers and LMC must be in the same network (regardless of connection type). When LMC is powered up it creates a Wi-Fi hotspot with the following name: “LMC ID123456789”. Connect to the hotspot and configure the WiFi hotspot name and password to connect LMC to the internet.

8. Connect to the VOOL Network

• Connect the Ethernet cable to the left Cat port on the LMC for Ethernet. The upper green LED on the LMC will start blinking once the internet connection is established.

• For WiFi, the LMC can connect to the WiFi network locally via the browser running inside the LMC. Make sure to enter the correct network name and password for WiFi access.

• Configure the same network in all chargers connected to the LMC to activate wireless load management.

• The LMC has an in-built 4G connection and antenna. It will try to connect to a 4G network if no other connection is available. Ensure that the LMC is not placed underground or in a closed room. For a faster and more reliable connection, connect the LMC with WiFi or Ethernet.

• 4G connection for the LMC is limited in speed and capacity. A faster connection and larger capacity can be purchased separately through VOOL.

9. Add the LMC in the VOOL Portal

  1. To add the LMC to the VOOL Portal, navigate to and log in.

    You can access the VOOL Portal via mobile phone, tablet, or PC.

    Click “Add a Device”

    • add a new site or select existing

    • add device

    • select manufacturer - VOOL

    • enter serial and PIN

    • if device is connected online it will appear in the list of devices.

10. Adjust LMC Settings in VOOL Portal

  • Find the LMC device in your account.

  • Set the fuse rating in amperes and other settings from here.

  • During the installation of the Load Management Control (LMC) system, you must match the current setting with the main fuses’ size and capacity to ensure proper calibration of the DLM system and avoid potential damage.

11. Connect to a Charger(s) (Single-Point Load Balancing)

*If you are installing multiple LMCs for multi-residential, or commercial properties, skip this step and move on to step 12.

Once you have set up the LMC, you are ready to add chargers or link LMC with existing chargers on the site.

Set up Multilevel and Multipoint Load Balancing
