4. Installation

4.1 Pre-Installation Checklist

• Verify all power to the battery system is disconnected.
• Gather necessary tools: screwdrivers, wire strippers, crimpers, mounting hardware.
• Ensure adequate space for mounting and access to the switch.

4.2 Mounting the Switch

1. Choose a suitable mounting location that is easily accessible and protected from physical damage.
2. The switch features removable side plates and a back cover, allowing for flexible cable entry and mounting configurations. Remove these as needed for your installation.
3. Mark the mounting holes using the switch as a template.
4. Drill pilot holes if necessary.
5. Secure the switch using appropriate fasteners (not included).

4.3 Wiring Connections

The 701-S is designed as a selector switch for two battery banks. It utilizes screw terminals for secure connections.

1. Identify the positive (+) terminals for Battery 1, Battery 2, and the Common Load terminal. Refer to the diagram on the switch or included wiring schematic (if provided separately).
2. Connect the positive (+) cable from Battery 1 to the Battery 1 terminal on the switch.
3. Connect the positive (+) cable from Battery 2 to the Battery 2 terminal on the switch.
4. Connect the positive (+) cable leading to your boat's electrical system (load) to the Common Load terminal.
5. Ensure all connections are tight and free from corrosion.
6. Re-install any removed side plates or back cover.

Note: BEP Marine recommends isolated battery systems for optimal performance and safety. Ensure your system design aligns with best practices for marine electrical installations.

5. Operation

The BEP Marine Master Battery Switch Mini Contour 701-S operates manually via a rotary actuator. It typically features positions for Battery 1, Battery 2, and OFF.

• OFF: In this position, all battery banks are disconnected from the load. This is the recommended position when the vessel is unattended or during maintenance.
• Battery 1: Select this position to connect Battery Bank 1 to the vessel's electrical system.
• Battery 2: Select this position to connect Battery Bank 2 to the vessel's electrical system.
• Switching: To switch between battery banks or to the OFF position, rotate the knob firmly to the desired setting. Avoid switching under heavy load if possible to minimize arcing and wear on the contacts.

After installation, turn the switch to the desired battery bank position (e.g., Battery 1) and verify that power is supplied to your vessel's electrical system.

6. Maintenance

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

• Cleaning: Periodically clean the exterior of the switch with a damp cloth. Do not use harsh chemicals or abrasive cleaners.
• Connection Check: Annually, or more frequently in harsh marine environments, inspect all wiring connections for tightness and corrosion. Loose or corroded connections can lead to resistance, heat buildup, and power loss.
• Visual Inspection: Check the switch housing for any signs of physical damage, cracks, or discoloration.

Always ensure power is disconnected before performing any maintenance that involves touching electrical connections.
