Non-fused negative battery terminal MG LFP 24 V – MG4000034

The MG4000034 reference is a non-fused negative battery post from MG Energy Systems. It is designed for 24 V LFP battery systems and belongs to the fuse family, although it is itself non-fusible.

This terminal's function is to replace a protected pole (fuse) when the overall battery system protection architecture, validated by MG Energy, requires it. It allows a negative connection without an integrated fuse, necessitating an external calculated protection.

Using a non-fused terminal block such as the MG4000034 is required when the DC protection architecture of the MG LFP 24 V battery system is designed so that overcurrent protection is handled at a higher or centralized level, making a local fuse on the negative terminal redundant or inappropriate.

The reference number (SKU) for this battery charger is MG4000034.

The content provided with part number MG4000034 is a non-fused negative battery terminal from MG Energy. No other components are included.

For a complete and secure installation of the MG4000034 dock, you will need to provide separately:

A fuse (if required for overall system protection)Appropriate cablesLugsA protective coverScrewsA complete system protection study

The declared shipping weight for the MG4000034 negative battery terminal is 0.05 kg.

The country of origin for part number MG4000034 is India.

The customs code (HS code) for the non-fused negative battery terminal MG4000034 is 85361090.

No, the MG4000034 terminal is not classified as dangerous goods for transport according to the export dealer of MG Energy.

This socket is compatible with MG Energy Systems HE and LFP battery series.

The MG4000034 terminal is specifically compatible with the following 24 V LFP battery models, as documented in the 2026 manual:

MGLFP241230MGLFP242230MGLFP241280MGLFP242280MGLFP241304MGLFP242304

It is imperative not to install this terminal on a battery or polarity not explicitly listed in the manufacturer's documentation without prior validation from MG Energy Systems. This ensures the safety and compliance of the system.

The product documentation specifies compatibility with MG Energy Systems HE and LFP battery series. Using this charger with batteries from other manufacturers is not recommended without explicit validation from MG Energy to ensure system safety and performance.

Installation of the MG4000034 battery charger must be carried out by a qualified professional. A power-off installation is mandatory for safety reasons.

During installation, it is crucial to:

Work with the power off.Respect the polarity strictly.Apply the specified torque value.Ensure adequate insulation.Follow the protection architecture detailed in the MG Energy manual.

Removing the local fuse on the negative terminal must be compensated for by a calculated protection of the system as a whole. This means that overcurrent protection must be provided elsewhere in the electrical architecture, in compliance with specifications and safety standards.

Before installation, it is advisable to carefully check:

System voltage. Expected currents. Coordination of protections. Adequate cooling. Interfaces of the complete system. These checks are essential for safe and functional integration.

Before powering the system back on after installing the socket, it is essential to check:

The continuity of the connections.
The correct positioning of the enclosure (if applicable).
The coordination of the protections for the entire system.
