Connecting to a Third Party Device

All SLXi trailer units come fitted as standard from factory with a Low Voltage Disconnect (LVD) switch to accommodate for 3rd party device connections. The LVD switch ensures that all SLXi units provide a dedicated device connection point for external devices, while also preventing battery discharge/depletion of the EnergyONE battery during unit idle periods.

Important All external device connections must be connected through the LVD switch as per instructions detailed in the SLXi Installation Manual/External Device Connection with LVD (Click in the following location to download - www.emea-user-manuals.thermoking.com). Failure to connect external devices through the LVD switch may result controller and/or battery related failures being rejected by warranty. The LVD switch acts as a protective medium between the SLXi unit electrical system and external device(s).

Connecting a Third Party Device

LVD Switch

The function of the LVD switch is as follows:

  • Disconnects power to external devices when battery voltage drops below 12.1V (for longer than five minutes).

  • Automatically resets when system voltage rises above 13V (for longer than 10 seconds).

  • Provides connection point in control box for up to three external devices.

  • Recommended total maximum current draw from all connected devices combined (At all times, not just when the unit is power down): 2 Amps.

    • Excessive current draw due to external devices when unit is powered down will result in the LVD switch disconnecting the output after a short period of time (possibly within hours - depending on total current draw).
