Operating Tips; Troubleshooting - Defort DCI-300D Bedienungsanleitung

Ventilated: keep the area surrounding the inverter clear to en-
sure free air circulation around the unit. Do not place items on
or near the unit whilst it is operating. A fan is helpful if the unit is
operating at maximum power outputs for extended periods of
time. If the internal temperature of the inverter exceeds 90 ºС
the inverter will shut down and restart when it has cooled.
• Safe: do not position the inverter near any fl ammable mate-
rial 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 consump-
tion of the item you wish to operate is specifi ed at the rated
watts or less. The inverter has overload protection so it is safe
to try and operate equipment rated at the specifi ed watts or
less. The inverter will shut down if it is overloaded. The over-
load 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 re-
quire 2-6 times their wattage rating to start up. The most de-
manding in this category are those that start under load such
as, compressors 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 protection so will
simply shut down if overloaded. To restart the unit after over-
loading 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 equip-
ment 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 in-
verter will not operate whilst the engine is being turned over as
battery voltage drops substantially 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 hazardous
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 automatically shut
down when the input voltage exceeds 15.5V DC
• Short circuit protection: The inverter will shut down. Re-
move the short circuit and the inverter will reset.
• 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 sensor in-
side the inverter reaches 65 degrees C, the unit will auto-
matically shut down. In this instance, allow at least 15 min-
utes before attempting to restart the inverter and always
disconnect appliances.

• Low battery alarm: The alarm will sound if the input volt-
age drops below 10.5V,this is an indication that the battery
needs to be recharged. Users should discontinue 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 recharge 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, overheated
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 con-
nected 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 without
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 ex-
cessive 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 incandes-
cent 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
