MTS LVD Kit Installation
This section provides a quick reference for installation of the LVD Kit for use with both MTS2 and
MTS4. The MTS LVD kit consist of an aluminium housing including Power relay and push button for
hot activation of LVD and controller cable for plugging the LVD to a MTS base station.

activate cabin light, and
•
power up the Base station power supply, which also will enable normal activation of the LVD.
Procedure 4-9 describes how to install the MTS LVD kit. For installing the MTS
LVD kit, the following tools are needed:
•
PZ2 and PH2 screwdriver
