• Fuse Box: Protects individual circuits.
• In/Out 50A Andersons: High-current connection points.
• DCDC Inputs: Dedicated inputs for alternator and solar (on DCDC models).
• Rocker Switches: 5 x 20A backlit switches for controlling accessories.

Wiring Switches

1. Ensure the unit is disconnected from the battery before starting.
2. Remove the 4 screws to open the Control Hub lid.
3. Select appropriate spade and ring terminals for your accessory wiring.
4. Cut the grommets on the side or bottom of the unit to route wires.
5. Strip 1cm of insulation from cables and crimp terminals.
6. Connect the spade terminal to the bottom blank tab on the switch.
7. Connect the negative ring terminal to a spare screw position on the negative bus bar.
8. Tuck cables in and re-fasten the lid.

Battery Installation

1. Remove the 4 screws and open the Control Hub.
2. Route battery wires through the grommets on the side or bottom.
3. Remove the bolt and washer from the positive and negative terminal posts on the rear.
4. Attach the negative cable to the B side of the shunt and the positive cable to the positive terminal.
5. Fasten the bolts securely.
6. Connect the other end of the cables to the battery, starting with the positive terminal.
7. Ensure cables are supported and not rubbing.

Battery Monitor Setup

Access the settings menu by pressing and holding the SET button:

• SET1 (Overvoltage): Set 0.5V above the battery's stated maximum voltage.
• SET2 (Undervoltage): Set the voltage at 0% capacity (e.g., 10.5V for Lithium).
• SET3 (Overcurrent): Match with the battery's rated maximum current.
• SET4 (Capacity): Set to the actual capacity of the connected battery.
• SET5 (Percentage): Set current battery percentage to 100% (recommended to charge to 13.5V first).
• SET6 (Backlight): Adjust screen brightness.

Connecting Chargers

The Control Hub supports multiple charging methods:

• AC Charger: Connect to any in/out Anderson plug.
• Regulated Solar Panel: Connect to any in/out Anderson plug.
• Alternator: Connect to the DCDC charger alternator input using the Plug & Play DCDC Wiring Kit.
• Unregulated Solar Panel: Connect to the DCDC charger solar input Anderson plug.

Note: Solar panel open circuit voltage must not exceed 32V.

Safety Precautions

• The lid must remain closed and screwed tight during operation.
• Do not allow metal objects to fall into the unit or ports.
• Do not use with life support systems or medical devices.
• Ensure the charging profile matches your battery type to prevent fire or damage.
• Do not expose the unit to water, rain, or snow.
