5.3 Wiring External Devices

The power box features a 6-way fuse box for wiring external 12V devices. Each circuit is protected by a fuse.

1. Identify the positive (+) and negative (-) terminals for each circuit within the fuse box.
2. Connect the positive wire of your 12V device to an available positive terminal in the fuse box.
3. Connect the negative wire of your 12V device to a common negative bus bar or terminal.
4. Ensure the appropriate fuse size is installed for each connected device to prevent overload. Fuses can be changed as needed.
5. Use the provided label stickers to clearly mark the function of each switch for easy identification.

6. Operating Instructions

6.1 Powering On/Off and Circuit Control

1. Once the battery is connected, the power box is ready for use.
2. Use the individual rocker switches to turn on or off the connected 12V devices. The switches illuminate when active.

6.2 USB and Type-C Output

The power box includes a 12V 4.8A USB and Type-C output for charging mobile devices or powering small USB-compatible electronics.

1. Plug your USB or Type-C charging cable into the corresponding port.
2. The integrated display shows the output voltage.

6.3 Dimmer Switch Operation

The dimmer switch controls the brightness of connected lights (if compatible with 12V dimming).

1. Turn the dimmer knob clockwise to increase brightness (MAX).
2. Turn the dimmer knob counter-clockwise to decrease brightness (MIN) or turn off the connected light.

6.4 Low-Voltage Disconnect (LVD)

The LVD feature protects your battery from over-discharge, extending its lifespan.

1. The internal circuit board allows you to set a specific low-voltage threshold.
2. When the battery voltage drops below the set threshold, the system will automatically cut off power to prevent further discharge.
3. Refer to the internal circuit board for voltage regulation buttons ('+' and '-') and the voltage display to adjust the LVD setting.

7. Maintenance

• Regularly inspect all wiring connections for tightness and signs of wear or corrosion.
• Keep the exterior of the power box clean and free from dust and debris. Use a soft, dry cloth for cleaning.
• Check fuses periodically. If a device stops working, check its corresponding fuse in the 6-way fuse box and replace if blown. Always replace with a fuse of the same rating.
• When not in use for extended periods, remove the Dewalt 20V battery from the adapter.
