Operation
Step 1: Plug Inverter into vehicle lighter/accessory outlet.
For PV375USB and PV400USB models: This unit contains a pair of DC input terminals to connect a
3 ft. cigarette lighter plug cable* or optional 3 ft. battery cable with alligator connectors that directly
attaches to a battery's DC terminals**.
*To avoid overheating, do not exceed 180W when using the cigarette lighter adapter. **Always connect red
connectors to red battery terminals (POS, P , +) and black connectors to black battery terminals (NEG, N, -). For
unmarked terminals, the positive post usually has a larger diameter than the negative post. When disconnecting the
charger, reverse the order of the connecting steps.
Step 2: Turn on Inverter.
Step 3: Plug equipment into the Inverter.
Determine your equipment's total wattage.*** Do not connect more watts than your Inverter's
Output Power (Maximum Continuous Watts); see Specifications. See back page for typical
equipment runtimes. Also see back page for important note concerning the limitations of vehicle
electrical systems.
*** Wattage ratings are usually listed in equipment manuals or on nameplates. If your equipment is rated in amps,
multiply that number times AC utility voltage to determine watts. (Example: a ¼ in. drill requires 2½ amps.
2½ amps × 120 volts = 300 watts.)
Maintenance
Your Inverter requires no maintenance and contains no user-serviceable parts (except for replaceable
DC fuses, where applicable).
Troubleshooting
Please check the following before sending the Inverter in for warranty replacement:
Symptom
Inverter does not turn
ON when power switch is
turned ON.
Inverter is unable
to power connected
equipment.
Connected equipment
experiences audio/video
distortion.
16-09-010-933643_revA.indb 2
Possible Cause
Automatic Inverter shutdown due
to low battery voltage (<10V).
Automatic Inverter shutdown due
to output overload.
Blown fuse.
Battery running low. Low battery
voltage reduces Inverter power
output.
Connected equipment load
exceeds Inverter's maximum
continuous output power.
Note: Fault LED will illuminate during
an overload (PV200USB
& PV400USB only).
Loose connections.
Audio/video interference.

Correction
Turn Inverter OFF and start engine
to recharge vehicle battery. Only use
Inverter with engine running.
Turn Inverter OFF and remove
overload by unplugging high-wattage
devices. Load should not exceed
your Inverter's maximum continuous
output power (see Specifications).
Replace fuse with standard
automotive fuse of identical
amperage, where applicable (see
Specifications).
Turn Inverter OFF and start engine
to recharge vehicle battery. Only use
Inverter with engine running.
Turn Inverter OFF and remove
overload by unplugging high-wattage
devices. Load should not exceed
your Inverter's maximum continuous
output power (see Specifications).
Check and secure all connections.
Reposition equipment antennas and
Inverter.
