Defort DCI-600 [9/28] Operating tips

• Overload protection: The inverter will automatically

shut down when the continuous power consumption

is over the rated Max power output.

• Overheating protection: When the temperature sen-

sor inside the inverter reaches 65 degrees C, the

unit will automatically shut down. In this instance,

allow at least 15 minutes before attempting to restart

the inverter and always disconnect appliances.

• Low battery alarm: The alarm will sound if the input

voltage drops below 10.5V,this is an indication that

the battery needs to be recharged. Users should dis-

continue operation of the appliance(s) at this point,

as the inverter will shut down shortly after the alarm

sounds. The vehicle engine should be started to re-

charge the battery. If the low battery alarm sounds

when the battery is fully charged follow the steps for

solving lack of output power in the troubleshooting

guide.

The alarm will sound if the inverter is overloaded, over-

heated or if there is an excessive voltage drop between

the battery and inverter.

NOTE:

It is normal for the alarm to sound while the unit is being

connected to, or disconnected from the power source,

this is not indicative of a problem.

TROUBLE SHOOTING

No AC output

• Inverter is too hot

• Disconnect load from inverter. Operate inverter with-

out load for a few minutes. Reconnect load.

Motorised power tool won’t start

• Excessive start up load

• If appliance does not start, then appliance is drawing

excessive wattage and will not work with inverter

Motorised power tool does not operate at correct

speed

• purely inductive load

• Make the load not purely inductive. Operate an in-

candescent lamp at same time as motor

Television/Radio interference

• Snow in picture, buzz in speaker

• Keep inverter and antenna distant from each other.

Use shielded antenna cable. Connect antenna to

ampliﬁ er

• Safe: do not position the inverter near any ﬂ amma-

ble material or in a position that may accumulate

ﬂ ammable fumes or gases.

OPERATING TIPS

Rated versus actual current draw.

Most electrical equipment has labels that indicate the

power consumption in amps or watts. Ensure the power

consumption of the item you wish to operate is speci-

ﬁ ed at the rated watts or less. The inverter has over-

load protection so it is safe to try and operate equip-

ment rated at the speciﬁ ed watts or less. The inverter

will shut down if it is overloaded. The overload must be

removed before the inverter will restart; resistive loads

are the easiest for the inverter to run. However larger

resistive loads, such as, stoves and heaters usually

require more wattage than the inverter can deliver on

a continuous basis. Inductive loads such as, TV’s and

stereos require more current to operate than resistive

loads of the same wattage rating. Induction motors as

well as some televisions may require 2-6 times their

wattage rating to start up. The most demanding in this

category are those that start under load such as, com-

pressors and pumps. Testing is the only deﬁ nitive way

of determining if a speciﬁ c load can be started and how

long it will run. The inverter is ﬁ tted with overload pro-

tection so will simply shut down if overloaded. To restart

the unit after overloading remove the overload and if

necessary turn the power switch off and then on.

Battery operating time.

With a typical vehicle battery, a minimum operating time

of 2 to 3 hours can be expected. In most instances, 5

to 10 hours of operating time is achievable however

it is recommended that the operator starts the vehicle

every 2 to 3 hours to recharge the battery system thus

guarding against unexpected equipment shut down

and ensuring that there is still sufﬁ cient power to start

the engine. The inverter’s built in alarm will sound if

the DC voltage drops below 10.5V. The inverter can

be used whether or not the vehicles engine is running

however the inverter will not operate whilst the engine

is being turned over as battery voltage drops substan-

tially whilst the engine is being started. In most cases

the inverter can be left connected to the battery when

not in use as it draws very little current, however if the

vehicle is to remain unused for several days disconnect

the inverter from the battery.

In built protection.

Your inverter monitors the following potentially hazard-

ous conditions:

• Low battery voltage: This condition is not harmful to

the inverter but could damage the power source. An

audible signal will sound when input voltage drops

to 10,5 V. The inverter automatically shuts down

when input voltage drops to 10.0V. When the power

source input voltage is above 10.5V the inverter may

be restarted.

• Over voltage protection: The inverter will automati-

cally shut down when the input voltage exceeds

15.5V DC

• Short circuit protection: The inverter will shut down.

Remove the short circuit and the inverter will reset.
