1RECHARGEABLE APPLIANCES

Certain rechargers for small

nickel cadmium batteries

can be damaged if connected

to the unit. Two types of

equipment are particularly

prone to this problem:

1. Small battery operated

appliances that can be

plugged directly into

an AC receptacle for

recharging, including

flashlights, razors, and

night lights.

2. Certain battery chargers for

battery packs used in hand

power tools, specifically

those that have a

WARNING label stating

that dangerous voltages

are present at the battery

terminals.

Problems do not occur with

the vast majority of battery

operated tools, most of which

use a separate charger or

transformer that plugs into

an AC receptacle and produces

a low voltage output. If the

label on your tool’s AC adapter

or charger states that is

produces a low voltage AC or

DC output (less than 30 volts)

you can safely power the

charger.

CAUTION

BEFORE USING YOUR INVERTOR

In order to check the

performance of your

unit before using it, please

have the following

on hand:

1. A 12 volt DC power source

(such as a vehicle battery).

2. A test load such as a lamp

or other small appliance

that can be plugged into

the AC receptacle on the

inverter.

Power Source

You will need an 10.4 to

14.4 volt DC power source

capable of supplying enough

current to run the test load.

As a rough guide, divide the

wattage of the test load by 10

to get the current (in amperes)

that the power source must

supply. A fully charged

standard automotive battery

will work fine.

Connecting to the

Power Source

Your unit connects

directly into the cigarette

lighter socket of your car.

Do not connect to the power

source if flammable fumes

are present. Explosion or

fire may result.

WARNING

2QUICK CHECKOUT

Quick Checkout (continued)

To connect your inverter

to the power source:

1. If the power source is a DC

power supply, switch it off.

2. Insert the cigarette lighter

plug into your vehicle’s

cigarette lighter.

Testing

The inverter will come on

automatically. It should supply

power to the load. If the

inverter does not appear to

work properly, refer to the

Troubleshooting Guide on

page 7.

OPERATION

5V/2.1A USB Port

CPI190_MANL.indd 4 12/22/14 8:33 AM

The location where you should

use your unit must be:

•dry–Do not use the unit

where water can drip or

splash on it.

•cool–Ambient air

temperature should be

between 30˚ and 105˚ F

(0˚ and 40˚ C). The cooler

the better.

•ventilated–Allow at least

1 inch (3 cm) of clearance

around the unit for proper

air flow. Make sure that

ventilation openings on the

ends of the unit are not

obstructed.

To prevent fire, do not

cover or obstruct

ventilation openings.

The inverter must only

be connected to batteries

with a nominal output

voltage of 12 volts.

It will not work with

a 6 volt battery, and

will be damaged if it is

connected to a 16 volt

or greater battery.

4CONTROLS & INDICATORS

Powering Up

To apply power to the CPI190,

simply plug in to 12 Volt DC

source (cigarette lighter).

Power/Fault Indicator

The “fault” indicator of your

CPI190 will light whenever

the unit detects excessively

high or low input voltage,

or begins to overheat.

CAUTION NOTE: Make sure

you unplug inverter from

power source before you

leave your vehicle.

OPERATING LIMITS

INPUT VOLTAGE/AUTO SHUTDOWN

Power Output

AC Output:

Your CPI190 will deliver

130 watts continuously.

(NOTE: the wattage rating

applies to resistive loads.)

USB Output:

5 Volt continuous output.

Input Voltage

Your CPI190 will operate from

input voltage ranging from

10.4 to 14.4 volts. Optimum

performance occurs when the

voltage is between 12 and

14 volts.

The inverter will automatically

shut down if the input voltage

drops below 10.0 ± 0.3 volts.

This protects the battery

from being over-discharged.

The inverter will restart when

the input voltage exceeds

12.0 ± 0.3 volts.

The inverter will also shut

down if the input voltage

increases to 15.5 ± 0.5 volts.

This helps protect the unit

from damage due to excessive

input voltage. Although the

inverter is protected in this

way, it may still be damaged

should the input voltage

exceed 16 volts.

Automatic Shutdown

The unit will automatically

go into thermal shutdown if

it becomes overheated due to

excessive input voltage, poor

circulation or high ambient

temperature. 6

MAINTENANCE & SERVICE

POWER CONSUMPTION

For each piece of equipment

you will be powering with

your CPI190, you must

determine the battery’s

capacity (how long the

battery can deliver a

specific amount of current).

For example, automotive

batteries usually provide

25 amperes of current.

A battery with a reserve

capacity of 180 minutes

can deliver 25 amperes for

180 minutes before it is

completely discharged.

Calculate the total watt-

hours of energy consumption

(power X operating time),

then divide the watt-hours

by 10 to determine how may

12 volt ampere hours will be

consumed.
