Description Of Functions - IVT DSW 12 V Mode D'emploi

Operation
• The product may only be operated in a dry environment. It may not get humid or wet, otherwise there
is a risk of life-threatening electrical shocks.
• The use of the product under unfavorable environmental conditions must be avoided under all circum-
stances. Unfavorable environmental conditions include: ambient temperatures above 50 °C, flammable
gases, solvents, vapours, dust, relative humidity in excess of 80 %, and moisture.
• The device may not be operated or charged in the presence of flammable materials or gases. Explosion
hazard!
• Ensure proper ventilation during the operational phase, never cover the voltage converter and connect-
ed devices.
• Protect the voltage converter against electro-magnetic fields as well as impacts and vibrations.
• Protect the voltage converter against heat! Should the voltage converter become too hot due to high
ambient temperatures, the overheat protection switches the device off to avoid consequential damage.
In this case, wait until the device has cooled down.
• Avoid sudden differences in temperature! This may cause the formation of condensation water in the
voltage converter! In this case, the voltage converter must be adjusted to the new ambient temperature
before start at a well ventilated place for a least one hour.
• Keep the voltage converter away from ignition sources or open fire! Explosion hazard!
• The operation of electrical loads may lead to high currents of about 170 A.
Please use sufficiently dimensioned wire cross-section for the connection wires.
• Please use a secondary battery, for the operation of powerful loads with an inverter, which is used in a
vehicle. Do not only use the vehicle battery.
• Operate fluorescent tubes only in conjunction with this voltage converter if they are equipped with an
electronic starter or electronic ballast. Using conventional starters may lead to severe damage of the
voltage converter.
• AC outputs of several power sources may not be connected in parallel! Do not connect AC generators or
mains voltage to the AC output of the voltage converter. This leads to the immediate destruction of the
voltage converter!
• Never open the voltage converter! Even after disconnecting the device from the battery there may be
hazardous voltages in the interior of the device. This is why service and repairs may only be carried
out by authorized and qualified personnel.
Notes on the battery
• If used improperly, lead batteries are a high risk for humans, animals and the environment. Always
observe the safety instructions of the battery manufacturer!
• Lead batteries contain aggressive corrosive acids. Avoid eye and skin contact with liquids from the bat-
tery! Never disassemble lead batteries! Wash the parts of the skin affected thoroughly with water and
soap. If acid enters the eye, immediately flood the eye with running, clear and cool water! Then seek
medical help immediately! If acid contacts your clothing, wash immediately with soap and water!
• The use of electronic devices with an inverter and the simultaneous charging of a battery with the
generator of a vehicle may lead very fast to an overheating of the battery.
Danger of fire!
• The operation of electrical loads may lead to high currents of about 170 A. Please always observe the
data sheet of the battery producer, if the battery is able to supply the required current over the whole
load ON time. Suitable vehicle batteries must have a cold test current of at least 750 A - 800 A.
Warning:
!
Improper assembly may cause hazardous contact voltages even on the closed device!
14 3 years manufacturer's warranty. Rechargeable batteries excluded.

DESCRIPTION OF FUNCTIONS

The voltage converters of the DSW series are modern, microprocessor-controlled devices which were
developed for mobile power supply. The voltage converters of the DSW series convert lower DC input
voltage into higher AC output voltage and thus allow for the usage of conventional 230 V AC consumers
on the road.
These devices offer real sinus alternating voltage which allows for a trouble-free operation also of diffi-
cult consumers such as PCs, TV systems and devices with transformers.
Of course, all inverters of the DSW series are equipped with all necessary safety features.
FEATURES
• Real 230 V AC 50 Hz sinus output voltage
• Galvanically isolated
• High efficiency
• Precise 50 Hz frequency
• Sleep function
• Standby function
• AC reversed input protection (only DSW-2000 versions)
• Output- and temperature-controlled fan
• Power start function for consumers with high starting current
• Overvoltage shutdown
• Adjustable, dynamic deep discharge protection
• Overload management
• Short-circuit shutdown
• Reverse polarity protection
• Temperature-activated protective circuit
• Various remote controls as accessories available
