Initial Operation; Standby-Funktion - IVT DSW Series Operating Instructions Manual

INITIAL OPERATION

To switch the voltage converter on and off activate the on/off switch (Nr. 8). Now you may connect your
230 V AC consumer.
The sequence of switching on/off and connecting the consumers is reversible.
When you switch off the voltage converter using on/off switch (Nr. 8) or the remote
i
control switch (FS-01/FS-02), no own power is required.
When you use the remote control (FB-04/FB-05) for this purpose, however, you only
switch off the 230 V AC output with it, but not the voltage converter. This is why it
continues to require own power. To save energy, we recommend using switch (Nr. 8) or the
remote control switch (FS-01/FS-02) only for switching off.
GENERAL NOTES FOR USING AC CONSUMERS ON VOLTAGE CONVERTERS
In general, all AC consumers can be used on a sinus voltage inverter. Observe, however, that for doing so
you are always restricted by the availability of the battery capacity and the output requirements of the
individual AC consumers.
For a better assessment of the battery reserve, we recommend to familiarize yourself with some rele-
vant characteristics of AC consumers. One important factor is the initial current. Most consumers require
a significantly higher starting current than indicated on the type plate of the device. E.g. bulbs require
starting current which is up to 8 times higher for approx. 1 second. Refrigerators and TV systems require
starting current which is up to 10 times higher for 1 to 3 seconds. This is why it is necessary when
choosing the voltage converter to ensure that corresponding output capacity is available. Therefore, a
voltage converter must provide a continuous output of 500 W (50 W x 10) to operate a small refrigerator
with a continuous output of 50 W.
Check the voltage requirements of the consumers to be connected. Connect only consumers whose
voltage specifications and output correspond with those of the voltage converter. Do not connect defect
or damaged consumers.
SLEEP FUNCTION
By using the sleep function the inverter automatically turns off, if the 230 V AC
output is not used for more than 10 minutes. Is this function active, there is no own
power consumption of the inverter. To restart the device it is necessary that the
user turns off and on again the main switch (Nr. 8) of the inverter. This function is
selected by DIP switch 1 (see picture).

STANDBY-FUNKTION

To conserve the life of the connected battery, you can activate the standby function
on your voltage converter. For this purpose activate DIP switch 2 on your device
(see picture). Now the voltage converter is in standby mode. This reduces the own
power consumption significantly. Now the device checks every whether load is
connected in intervals of 10 seconds. When the voltage converter recognizes a load
above standby level (see technical data), it connects the 230 V AC output and is thus
in normal operation again.
18 3 years manufacturer's warranty. Rechargeable batteries excluded.
SAFETY AND PROTECTION MECHANISMS
Reverse polarity protection
The inverter is protected against reverse polarity. This means that the voltage converter doesn't get
damaged if the battery is connected with wrong polarity.
Overvoltage shutdown
The voltage converter switches off as soon as the input voltage exceeds the given maximum value (1.33 x U
Dynamic deep discharge protection
The voltage converter switches off as soon as the input voltage drops below the set value. This is to
protect your battery against deep discharge. With the remote controls (FB-04/Webbox-LCD) units you
can make your own adjustment of the deep discharge protection individually between 9 V - 12 V on the
12 V version or 18 V - 24 V on the 24 V version. This adjustment is not possible without a remote control
unit. Factory settings of the deep discharge protection for the 12 V versions are 10.5 V and 21 V for the
24 V versions. The DSW voltage converter series is equipped with a dynamic deep discharge protection.
I. e., at high output the deep discharge protection is automatically reduced to a maximum of 1 V of the
set value.
i
The restart threshold is a permanently set value which cannot be changed.
The value is 12.5 V for the 12 V versions and 25 V for the 24 V versions.
Temperature-activated protective circuit
The voltage converter switches off when the temperature inside the device is too high.
Overload management
The voltage converter switches off when the output or the starting current of the connected devices is
too high. Then the voltage converter tries to restart (power start function). Should the device does not
restart after repetitive attempts the voltage converter is not suitable for the connected consumer. At the
DSW-2000 inverters there is no automatically restart if there has been an overload shut down for five
times. A manual reset with the main switch (Nr. 8) is necessary.
Short-circuit shutdown:
The voltage converter switches off when the output is short-circuited.
Warning:
!
The inverter automatically restarts, if the reason for shut down is removed.
USB OUTPUT 5 V
The USB output (Nr. 5) may be used to supply various 5 V consumers with maximum 500 mA.
This output is not suitable for data transmission.
