AC Output
CAUTION – Rechargeable Devices
• Certain rechargeable devices are designed to be charged by plugging them directly into an AC receptacle.
These devices may damage the inverter or the charging circuit.
• When using a rechargeable device, monitor its temperature for the initial ten minutes of use to determine if it
produces excessive heat.
• If excessive heat is produced, this indicates the device should not be used with this inverter.
• This problem does not occur with most battery-operated equipment. Most of these devices use a separate
charger or transformer that is plugged into an AC receptacle.
• The inverter is capable of running most chargers and transformers.

Soft Start Technology
Black & Decker's Soft Start Technology gradually "ramps up" the inverters power to slowly start appliances that
require a surge to get started. This gradual ramp up protects the inverter and the appliance, as well as the
power source, from damage and failure.
OPERATING INSTRUCTIONS
The Power Inverter must be connected only to batteries with a nominal output voltage of 12 volts. The unit will
not operate from a 6 volt battery and will sustain permanent damage if connected to a 24 volt battery.
Always connect the BDI400 to the 12 volt DC power source before plugging any devices into the unit.
The standard AC and USB outlets allow simultaneous operation of multiple devices. Simply plug the equipment
into the unit and operate normally. Ensure that the wattage of all equipment simultaneously plugged into the
BDI400 does not exceed 400 Watts continuous.
Connection to Power Source
The Power Inverter comes equipped with Battery Clips for connection to a power source.
Connecting to a Power Source Using the Provided Battery Clips
Use the provided Battery Clips (with cables) to connect the Power Inverter directly to the 12 volt power source
as follows:
1. Check to make sure the inverter's Power Pushbutton has been pressed OFF (no LEDs are lit) and that no
flammable fumes are present in the installation area.
2. Connect the RED cable to the RED post marked (+) on the back of the inverter . Connect the RED Battery Clip
to the POSITIVE terminal of the battery.
3. Connect the BLACK cable to the BLACK post marked (–) on the back of the inverter. Connect the Black
Battery Clip to the NEGATIVE terminal of the battery.
4. Make sure that all connections between cables and terminals are secure.
CAUTIONS
• Do not use with positive ground electrical systems.
• Reverse polarity connection will result in a blown fuse and may cause permanent damage to the
inverter.
Note: The majority of modern automobiles, RVs and trucks are negative ground.
Direct Hardwiring to Power Source (optional connection method; hardware not
included)
Use #6 AWG wire if the inverter to power source connection is 6 feet or less. For longer cable lengths use #4
AWG wire. In either case, protect the positive (+) wire from shorts by installing a 50 Amp. fuse or circuit
breaker close to the DC power source (battery) terminal.
1. Check to make sure the inverter's Power Pushbutton has been pressed OFF (no LEDs are lit) and that no
flammable fumes are present in the installation area.
2. Identify the positive (+) and negative (–) DC power source (battery) terminals.
3. Install a fuse holder or breaker close to the positive (+) terminal of the DC source (battery).
