3. Safety Information

WARNING: Always disconnect the negative battery terminal first when working on electrical systems to prevent accidental short circuits.

4. Setup and Installation

The Hella 265-002843011 battery switch is designed for screw-on mounting and inline connection. It can be installed on either the positive or negative battery cable, but it is crucial to install it on only one side of the circuit. For safety, it is generally recommended to install the switch on the positive cable.

4.1. Mounting Location

4.2. Installation Steps

  1. Prepare the Mounting Surface: Use the provided dimensions (refer to Figure 2) to drill appropriate holes for mounting the switch. The switch requires two mounting holes and a central hole for the rotary shaft.
  2. Mount the Switch: Secure the switch to the chosen surface using appropriate fasteners (not included).
  3. Prepare Cables: Ensure your battery cables have M10 ring terminals that fit securely onto the switch's M10 threaded posts.
  4. Connect Cables: Connect the battery cable from the battery to one terminal of the switch, and the cable leading to the load (or vehicle's electrical system) to the other terminal. Ensure connections are tight.
  5. Verify Wiring: Double-check all connections for correct polarity and tightness. Refer to the wiring diagram (Figure 3) for typical connection.

5. Operating Instructions

The Hella 265-002843011 battery switch operates with a simple rotary mechanism using the provided red key.

  1. To Turn ON: Insert the red key into the switch and rotate it clockwise to the "ON" position. The key should lock into place, completing the electrical circuit.
  2. To Turn OFF: Rotate the red key counter-clockwise to the "OFF" position. The key can then be removed, breaking the electrical circuit and preventing unauthorized use or battery drain.

Note: Always ensure that the engine or any high-current devices are turned off before operating the battery switch to prevent potential damage to the switch or electrical system from arcing.

6. Maintenance

Regular maintenance ensures the longevity and reliable operation of your battery switch.
