INSTRUCTIONS
1) Description: NDW240 can be supplied with any voltage between 11Vdc and 55Vdc, please respect the polarity. The output voltage can be programmed to any
voltage between 5Vdc and 55Vdc.
To prevent damage in case of reverse polarity, the device is protected by an internal not replaceable fuse.
NDW240 can be used in SELV and PELV circuits.
2) Installation: use DIN-rails according to EN 60715. Installation should be made vertically (see Fig.4). For better device stability fix the rail to the wall close to the point
where the device is to be mounted. In order to guarantee sufficient convection, we recommend observing a minimum distance to other modules (see Fig.3).
The device is provided with a thermal protection, a limited air flow can cause the thermal protection tripping.
The device automatically restarts after cooling.
To get normal operation reduce the temperature of the air surrounding the unit, increase the ventilation or reduce the load.

3
3) Connections: the device is equipped with pluggable screw terminals. To avoid sparks, do not connect or disconnect the connectors before having previously turned-off
input power and waited for capacitors discharge.
In order to comply with local certification, use appropriate copper cables of indicated cross section, designed for an operating temperatures of:
60°C (for ambient up to 45°C)
75°C (for ambient up to 60°C)
90°C (for ambient up to 70°C)
Strip the connecting ends of the wires according to the indication on Fig.5 and ensure that all strands of a stranded wire enter the terminal connection.
4) DC Input protection: NDW240 is equipped with internal fuse, ratings of DC line protection devices must be coordinated with input current indicated on the data sheet.
5) Overload (OL) / short circuit (SC) / overvolatge (OVP) / overtemperature (OTP) protections: Hiccup auto-reset and constant current limitation, user selectable.
Overload behaviour in hiccup mode: the output current is limited at 1.5xImax. When the programmed Imax value is exceeded a timer is started. If the load current
demand is not reduced below Imax for maximum 5 seconds the output is switched off and kept off for 10 seconds.
Overload (OL) error message is shown on the display, this cycle is then repeated until the load current demand is not decreased below Imax.
Overload behaviour in constant current mode: the output current is limited at Imax. If the load asks for more current than Imax the output voltage is progressively
decreased to keep the output current regulated at Imax.
Short circuit behaviour: the output is switched off in about 0.2 seconds and kept off for 10 seconds. Short Circuit (SC) error message is shown on the display details. This
cycle is then repeated until the short circuit is removed.
Input/output overvoltage protection: the unit is protected against external overvoltage applied to the input; for input voltages greater than 62V the device will shut
down. In case of an internal failure, a double protection circuit switch off the output and avoid output voltage higher than 62V potentially dangerous for the supplied
devices.
Overtemperature protection: The “Over Temperature (Ot)” error message appears when the internal temperature exceeds the safe limits. In this case the output is
switched off. The output is switched back on when the temperature decreased to safe limits.
6) Status Signals:
“DC OK” relay contact(24V/1A):
Contact closes when the output voltage is present and within the product specified output voltage regulation range
7) Redundant and parallel connection: NDW240 is equipped with an internal ORing circuit allowing direct parallel connection for redundancy without the need of an
external isolating diode. Parallel connection for power increase can be achieved connecting the output of the devices in parallel. Please keep the length of the input and
output cables of the 2 paralleled units the same length and cross section to achieve the best possible current balancing. Avoid exceeding 80% of the total available
output current. To use parallel connection the operating mode shall be set to “Parallel (PA)” in the configuration menu.
10) Feeding DC motors: it is possible to feed DC motors considering that when a motor starts-up under effort its consumption is much higher than the nominal current
and it can trigger overcurrent protection.
NOTE: motors can generate high conducted noise on the DC line. Therefore it is not recommended to feed on the same line motors and equipment sensitive to noise.
11) Warranty: power supplies are guaranteed free from factory defects for the time specified in the “Sales Conditions”.
Failures caused by misuse, external and/or abnormal events (i.e. overvoltage, over temperatures) or non-respect of above parameters and standards, are not covered by
warranty.
Opening the housing of the product makes warranty to be no longer valid.
In order to improve the products Nextys SA reserves the right to change product specifications, ratings and data without previous advice.

Short circuit
error
The “Short Circuit (SC)” error message appears when a
short circuit is detected at the output.
In this case the output is switched off and then restarted
after 10 seconds. This cycle is repeated until the short
circuit is removed.
Output
Overload
error
The “Overload (OL)” error message appears when the
output current exceeds Imax; it is only applicable when
“hiccup mode” current limitation is selected.
In this case the output is switched off after 5 seconds of
sustained overload and then restarted after 10 seconds.
This cycle is repeated until the output current is reduced
below Imax.
Over-
temperature
warning
The “Over Temperature warning (Ht)” appears when the
internal temperature is reaching unusually high levels. If
no modification of the ambient operating temperature
and / or load conditions is performed by the user, it is
highly possible that a “Over Temperature (Ot)” error
occurs, leading to the output switch off.
Over-
temperature
error
The “Over Temperature (Ot)” error message appears
when the internal temperature exceeds the safe limits. In
this case the output is switched off. The output is switched
back on when the temperature decreased to safe limits. In
case of repeated Over Temperature errors check the
device ventilation and/or reduce ambient temperature
