MTS LVD Kit Installation
This section provides a quick reference for installation of the LVD Kit for use with both MTS 2 and MTS
4. The MTS LVD kit consists of an aluminum housing including Power relay and push button for hot
activation of LVD and controller cable for plugging the LVD to an MTS base station.
When installed, the kit enables a low voltage disconnection option of batteries connected to an MTS
backup system, as a discharge of a battery pack below 40,5V can cause permanent damage.
The LVD also offers a push button which gives an override function, which powers up the Base station
power supply, which also will enable normal activation of the LVD.
Section Installing the MTS LVD Kit on page 122 describes how to install the MTS LVD kit. For installing
the MTS LVD kit, the following tools are needed:
• PZ2 and PH2 screwdriver
• Hammer
• Cutting tool for cable ties, etc.
• 2 Nm torque tool and crimp tool for ring terminal (optional)
The following figures depict the relay connection as diagrams.
