1. INTRODUCTION:
Smart-in is the new range of inverters designed and developed by NDS, which has
managed to create a series of professional products that reflect their own customers
expectations. hese Inverters have been designed to guarantee the best performance
in terms of safety, efficiency and reliability.
hanks to some special technical and innovative solutions Smart-in inverters are also
suitable for professional use.
Smart-inverters convert the direct current into the alternating current network in the
Modified Sine Wave (Smart-in SM) or Pure Sine Wave (Smart-in SP). his allows the
use of all the standard utilities for the mains (220V) with an accumulator 12V or 24V,
according to the version.
wo product lines are introduced as follows:
- Smart-in SM with Modified Sine Wave output, black and gray.
- Smart in-SP with Pure Sine Wave output, red and gray.
MAIN FEATURES:
✔High efficiency up to 90% and low self-consumption
✔Input with professional connectors
✔Predisposition for remote control ON/OFF
✔he input and output are completely isolated for a greater safety
✔High stability on the entire input voltage range (10V - 15.5V for the 12V
version 20V - 31V for the 24V version)
✔Ultra Low Noise operation with temperature controlled fan speed
he high efficency has been achieved thanks to an innovative circuit solution and by
using professional input connectors that prevent power loss on the main power path.
Input and output circuits are completely isolated by internal transformers, given to the
products a great level of safety.
he innovative circuit solutions adopted inside the Smart-in inverters allow to have a
great efficiency and operational stability over the entire operating input voltage range
with a low self-consumption.
Load and temperature controlled fan cooler, give an ultra low noise operation to the
inverter, that with a small load can work without fan, and also at bigger loads
conditions, the fan speed is controlled by the internal temperature of the inverter so it
can work in the condition as quite as possible. he speed of the fan cooler is
controlled by the entity of the load connected and by the temperature reached by the
device, giving to the inverter the possibility to work in ultra silent mode with utilities
of small entity and instead, with large utilities, to always work with a noise level as
low as possible.

7. INTERFERENCE PROBLEMS:
Some inexpensive stereo systems may emit a buzzing noise from their loudspeakers
when operated from the inverter. his occurs because the power supply in the audio
system does not adequately filter the modified sine wave produced by the inverter.
he only solution is to use a sound system that has a high quality power supply, or
use a pure sine wave inverter.
When the inverter is operating, it can interfere with television reception on some
channels. If interference occurs, try the following:
–Make sure that the chassis ground screw of the inverter is connected to the
ground system fo your vehicle.
–Make sure that the television antenna provides an adequate signal and the
antenna cable is in good conditions.
–Keep the cables between the battery and the inverter as short as possible, and
twist them together to reduce the radiated emissions.
–Move the television as far away from the inverter as possible.
–Do not operate high power loads with the inverter which the television is on.
10

8. BATTERY REQUIREMENTS:
Battery type and battery size strongly affect the performance of the power inverter.
herefore, you need to identify the type of loads your inverter will be powering and
how much you will be using them between charges. o determine the minimum
battery size that you need to operate appliances, follow these steps:
•Determine the wattage of each appliance and/or tool you will need to
simultaneously operate fromhe inverter. o do this, read the labels on the
requirement to be operated. Usually, power consumption s shown in watts. If it
is shown in amps, multiply by 220V to determine the wattage.
•Estimate the number of hours the equipment will be in use before recharge the
battery.
•Determine the total watt-hours of energy use, multiply the total running time
and the average power consumption power (in watts) and then divide it by 10 if
12V system, by 20 if 24V system. his result is the Ah energy needed to supply
the loads considered above.
•he minimum capacity of the battery, should be at least double the value of Ah
just obtained above.
Notes: Some appliances require an higher surge power to start, then the power
consumption decreases. And some appliances are not operating for long
periods of time. For example, a typical home-use coffee maker draws 500watts
during its brew time of 5minutes, but it maintains the temperature of the pot at
about 100watts. he typical use of a microwave is only for a few minutes,
sometimes at lower power; some exceptions to brief operating times are lamps,
Vs and computers.
When possible, recharge your batteries when they are about 50% discharged or
earlier. his gives the batteries a much longer life cycle than recharging when they
are more deeply discharged.
11

9. MOUNTIN THE INVERTER:
he inverter has four slots in its mounting bracket that allow the unit to be fastened
against a bulkhead, floor, wall or other flat surface.
Ideally, the mounting surface should be cool to the touch.
It is more electrically efficient to use longer AC wiring than DC wiring, so install the
inverter as close as possible to the 12V/24V DC power source.
he inverter can be operated in any position, but if it si installed on a vertical wall we
recommend to mount it with the longest side parallel to the floor.
For safety concern, you can connect a DC-rated fuse or a DC-rated circuit breakers
on the positive cable line in your power system, following these recommendations
when you purchasing fuses or circuit breakers.
Select a fuse or circuit breaker with a proper rating (e.g.:1000W advice 150Adc,
1500W advice 200Adc for the 12V version, while just use fuses with a maximum
current equal to half in the case of 24V inverters with the same power)
9.1 INSTALLATION STEPS:
•Check to be sure the power switch of the inverter is turned off and that no
flammable fumes are present.
•Identify the positive (+) and negative (-) battery terminals.
•Install a fuse holder or breaker close to the positive (+) terminal of the battery.
•Connect a length of wire on one side of the fuse holder or circuit breaker.
Connect the other end of the wire to the positive (+) terminal of the inverter.
•Connect a length of wire between the inverter’s negative (-) terminal and the
battery’s negative (-) terminal.
•Connect a short length of wire to the other terminal of the fuse holder or circuit
breaker. Mark it “positive” or “+”.
•Connect the free end of the fuse or breaker wire to the positive terminal of the
battery.
•Insert a suitable fuse in the fuse holder.
•Check to be sure that all connections between battery clips, terminals and fuses
are secure and tight.
9.2 AC LOADS CONNECTION STEPS:
•When you have confirmed that the AC appliances to be operated is turned off,
plug an appliance into the AC outlet on the front panel of the inverter.
•urn ON the inverter.
12

•urn the appliance on.
•Plug in additional appliances and turn them on.
Notes: 1. Plug the cord from the AC appliances you wish to operate into the
AC receptacle. When turn ON the inverter the Red and Green LEDs both lit for
3~5seconds then the red LED not lit, the green LED indicator lights to indicate
that the inverter is functioning. Make sure the combined load requirement of
your equipment does not exceed the output rating of the inverter.
•urn OFF the inverter. he over load LED may briefly “blink” and the audible
alarm may also sound a short“chirp.” his is normal. his same alarm may also
sound when the inverter being connected to or disconnect from the battery.
•When using an extension cord from the inverter to an appliance the extension
cord should not be longer than 1,5m and with appropriate section.
•When you plan to operate more appliances, please make sure plug and switch
ON the biggest one first and then smaller ones.
Caution: he inverter is engineered to be connected directly to standard
electrical and electronic equipments. Do not connect the power inverter to
household AC distribution wiring. Do not connect the power inverter to any
AC load circuit in which the neutral conductor is connected to ground (earth).
10. RATED VS. ACTUAL CURRENT OF LOADS:
Most electrical tools, appliances and audio/video equipment have labels that indicate
the power consumption in amps or watts.
Be sure that the power consumption of the item you wish to operate is less than
inverter’s rating power.( if the power consumption is rated in amps, simply multiply
by the AC volt (220V) to determine the wattage). he inverter will shutdown if it is
overloaded. he 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 electric stoves or heaters, usually require more wattage than the inverter can
deliver. Inductive loads. Such as V’s and stereos, require more current to operate
than do resistive loads of the same wattage rating. Induction motors, as well as some
televisions, may require 2 to 6 times their wattage rating to start up. he most
demanding in this category are those that start under load, such as compressors and
pumps. o restart the unit after a shutdown due to overloading, remove the overload
if necessary turn the inverter OFF and then ON.
13

11. FUSES REPLACEMENT:
he inverters are protected by our integral electronic circuit and will automatically
reset.
he inverters are fitted with internal fuse protections. If the battery is connected with
reverse polarity, the fuses burn protecting the system, so it is necessary to open the
device to replace them with the reserve ones of the same type. Normally after you
replace the new fuse, the inverter restart automatically. Sometimes it is possible that
there are additional faults for which it is necessary to contact the service of NDS.
OPTIONALS:
–he inverters are all predisposed to connect to an external remote controller.
–For the low power models 400W and 600W, it is possible to have
connection cables with clamps.
12. MAINTENANCE:
Minimal maintenance is required to keep your inverter operating properly,
periodically you should:
•Clean the exterior of the unit with a damp cloth to prevent the accumulation of
dust and dirt and check that DC cables are secure and fasteners are tight.
•Make sure the ventilation openings on the DC panel and bottom of the inverter
are not clogged.

18

Smart-in è la nuova gamma di Inverter progettata e sviluppata da NDS, che ha portato
alla nascita di una serie di prodotti professionali che ripecchiano le aspettative dei
propri clienti.
Questi dispositivi sono stati progettati per garantire le migliori prestazioni in termini
di sicurezza, efficienza e durata.
Grazie ad alcune speciali e innovative soluzioni tecniche gli inverter Smart-in sono
idonei per un uso professionale.
Gli inverter Smart-in convertono la tensione continua alla tensione alternata di rete
nella forma d'onda Sinusoidale Modificata (Smart-in SM) o Sinusoidale Pura (Smart-
in SP). Questo permette l'utilizzo di tutte le utenze standard per rete elettrica (220V)
tramite accumulatore a 12V o 24V a seconda della versione.
Si introducono così due linee di prodotto:
–Smart-in SM con uscita ad Onda Sinusoidale Modificata dal colore Nero e
grigio.
–Smart-in SP con uscita ad Onda Sinusoidale Pura dal colore Rosso e grigio.
CARATTERISTICHE PRICIPALI:
✔Alta efficienza fino al 90% e con un basso auto-consumo
✔Connettori di ingresso professionali
✔Predisposizione per in controllo remoto (ON/OFF) del dispositivo
✔Ingresso e uscita isolate galvanicamente per una magigore sicurezza
✔Grande stabilità di funzionamento su tutta la gamma di tensione di ingresso
(10V – 15.5V per la versione a 12V e 20V – 31V per quella a 24V)
✔Ultra silenzioso con la velocità della ventola controllata in funzione della
temperatura del dispositivo.
L'alta efficienza è stata ottenuta grazie ad un'innovativa soluzione circuitale e
all'utilizzo di connettori professionali sull'ingresso, che riducono l'energia persa nel
nodo con maggiore potenza. Ingresso e uscita sono galvanicamente isolate dai
trasformatori interni, conferendo un alto livello di sicurezza.
L'innovativa soluzione circuitale utilizzata nella serie Smart-in, permette di avere
un'elevata efficienza e stabilità di funzionamento su tutto, l'intervallo di tensione di
funzionamento in ingresso con un basso auto-consumo.
La velocità della ventola di raffreddamento è controllata dall'entità del carico
collegato e dalla temperatura raggiunta dal dispositivo, dando la possibilità
all'inverter di lavorare in modalità Ultra silenziosa con utenze di piccola entità e
invece, con grosse utenze di lavorare sempre con un livello di rumorosità il più basso
possibile.
