Installation

What’s in the box
The Battery Switch ships together with the following items:

• Battery Switch
• Instruction booklet with mounting template
• Interchangeable label sticker sheet
• 4 mounting screws

Mounting
The Battery Switch can be mounted in two ways:

1. Surface mount
2. Rear panel mount

The battery switch packaging contains an actual size cutout. Use this to mark the screw holes and in case of rear panel mount to mark the hole for the knob. For the dimensions of the Battery Switch see the Enclosure Dimensions [6] chapter.

1. Screw holes. 4 holes, one on each corner.
2. Mounting hole for rear panel mounting.

Label sticker
The Battery Switch ships with a sticker sheet containing 16 different label stickers.

• Select the sticker that best corresponds with the circuit the Battery Switch is used in.
• Remove the sticker from the sticker sheet and place it on the knob of the Battery Switch as indicated in below image.

Wiring
Wire the Battery Switch into the electrical system as follows:

• Disconnect the positive battery terminal.
• Mount the Battery Switch onto the desired surface (surface mount) or panel (rear panel mount).
• Remove the appropriate side plate for cable access. Do not remove the side plate facing upward as water may get in from the top.
• Use 120mm² (4/0 AWG) cables on all terminals to meet the Battery Switch current rating.
• Connect one terminal to the positive battery cable. Connect the other terminal to the positive cable of an alternator, load circuit or second battery (depending on installation type).
• Make sure that all nuts and locker washers are properly attached and the nut is tightened with a recommended torque of 8Nm (maximum 12.5Nm).
• Reconnect the positive battery terminal.

Operation

1. Twist the knob clockwise to turn the switch on.
2. Turn the knob counterclockwise to turn switch off.
3. Turn the knob a further 30° counterclockwise to turn switch off and to remove the knob.

Battery Switch knob removal
The knob of the Battery Switch can be removed. Use this feature to prevent unwanted operation of the switch. When the knob is removed, the switch is off.
Removal of the knob will prevent accidental switching, for example when system maintenance is carried out (safety), or when the system is left unattended for a certain time (battery discharge prevention).

To remove the knob

1. Ensure that engines and equipment connected to the same DC circuit as the Battery Switch are turned off.
2. Turn the Battery Switch knob counterclockwise to the “OFF” position has been reached.
3. Turn the knob a further 30° counterclockwise until the “Remove” position has been reached
4. Pull the knob away from the Battery Switch.

Technical specifications

The battery switch is suitable to switch under load. But if alternators, motors or sensitive DC loads are connected, first switch these off before switching the DC supply off.
