Fork lift charger, the blue/orange box toward the right of the photo


Maker Nexus uses an Eagletronic ML2 charger, model SR2400, fork lift charger to charge its electric fork lift. The fork lift is powered by a 36 Volt battery located in a compartment below the operator's seat.

The charges is powered by a 208 Volt 30 Ampere circuit, through a wall mounted fused safety disconnect switch to the left of the charger. According to the charger's nameplate, the maximum input current is 27 Amperes. Output of the charger is 36 Volts DC, with up to 140 Amperes.

The charger's internal control circuitry is powered by 36 Volts DC. AC power goes through a contactor inside the charger. The contactor does not have power to close until the fork lift battery is connected.

Yellow and green indicator lights on the right side of the charger's control panel show the status of power to the charger. These two lights work independently of each other:

  • The yellow light indicates that 208 Volts AC is being supplied to the charger, whether or not the contactor is closed.
  • The green light indicates that the 36 Volt battery is connected, whether or not the charger is powered.

When both of these indicator lights are on, the charger will operate automatically.

Charging the forklift

  • Before you begin:
    • Wear safety glasses when working on batteries or electricity.
    • Verify that the handle on the disconnect switch next to the charger is down, in the off position.
    • Verify that no indicators are lighted on the charger's control panel.
  • Access the battery:
    • Press the release lever on the fork lift steering column, and move it forward.
    • Press the release lever on the control column, and move it forward.
    • Press the release button, and lift the seat and battery cover out of the way.
  • Check electrolyte levels in battery.
  • Connections:
    • Disconnect the battery from the fork lift, by pulling out the plug connecting the battery and fork lift.
    • Plug the cable from the battery into the plug on the battery charger.
  • Start charging:
    • A green light on the charger indicates that the charger is connected to the battery.
    • Lift the handle on the disconnect switch next to the charger.
    • A yellow light on the charger indicates that 208 Volts is being supplied to the charger.
    • Other lights on the charger indicate charging progress.
