Connecting Accessories

NOTICE
Do not use the device to control or power a winch. Failure to follow this notice could cause damage to your vehicle or your device.
Accessory requirements:

• Verify the amperage rating of each accessory before wiring it to the Garmin PowerSwitch device. The device supports accessories up to 30 A for each channel and a maximum of 100 A for the entire system.
• Use 10 AWG (6 mm) wires for accessories that use 20 to 30 A. 2
• Use 12 AWG (4 mm ) wires for accessories that use 10 to 20 A. 2
• Use 14 AWG (2.5 mm ) wires for accessories that use less than 10 A.2
• Use the appropriate size terminals for all accessory connections.
• Crimp all terminal connectors securely.

1. Connect the positive wire from the accessory to one of the accessory terminals on the Garmin PowerSwitch device.
   

2. Connect the negative or ground wire to an unpainted ground stud on the vehicle frame, to a ground distribution block, or directly to the negative terminal on the battery.
   NOTICE
   Do not connect the accessory ground wires to the ground terminal (GND) on the Garmin PowerSwitch device. Failure to heed this notice could result in personal or property damage or negatively impact device functionality.

3. Verify that all electrical connections are tight and will not come loose during use.
   Connecting a Control Input
   You can connect to the control terminals to enable the Garmin PowerSwitch device to turn on customizable outputs.

• Verify that Bluetooth ® technology is enabled on your paired navigation device or smartphone.
• Move the navigation device or smartphone closer to your Garmin PowerSwitch device.
• Verify that your vehicle’s battery is supplying at least 12 V of power.
  The Garmin PowerSwitch device turns off all outputs automatically to preserve your vehicle’s battery if it is receiving less than 11 V of power (My accessories are not receiving power, page 5).

My accessories are not receiving power

• Verify the Garmin PowerSwitch device is receiving power from the vehicle battery.
• Verify that your vehicle’s battery is supplying at least 12 V of power. The Garmin PowerSwitch device turns off all outputs automatically to preserve your vehicle’s battery if it is receiving less than 11 V of power. Outputs turn back on when the device detects more than 12 V of power.
• Verify that all electrical connections are secure and will not come loose while operating the vehicle.
• Verify that each connected accessory draws less than 30 A. If an accessory draws more than 30 A, the device turns off that output automatically.
• Verify that the total system load is less than 100 A. If the device detects a system load of more than 100 A, it turns off all outputs automatically.
• Inspect all electrical connections for an electrical short circuit.

Can I mount the device in an engine compartment?

You can mount the device in an engine compartment as long as the temperature of the engine compartment does not exceed 85°C (185°F) . Do not mount the device near a turbocharger or an exhaust manifold.

Can the device get wet?

The device is designed to operate in wet conditions, and it can be submerged for limited periods of time. Always operate the device in accordance with the water rating listed in the device specifications (Garmin PowerSwitch Specifications, page 5). Submerging the device in water for prolonged periods of time may cause corrosion on the electrical contacts.
