INSTRUCTIONS
1) Description: NISO-20 can be supplied with any voltage between 10Vdc and 55Vdc, please respect the polarity. The output voltage will track the input voltage as
specified in the product datasheet.
To prevent damage in case of reverse polarity, the device is protected by an internal not replaceable fuse.
NISO-20 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) 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 <45°C)
and 75°C (for ambient < 60°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: NISO-20 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 over temperature protection.
OL exceeding the limits indicated on the data sheet, if applied to the device will make the output operate at on/off duty-cycle variable depending on OL value, air
temperature and device temperature.
Overload behaviour: Up to the overload limit there is no reduction of the output voltage. For output currents >Ilim the output is shut down and the Overload red LED
will be on.
Short circuit behaviour: The device enters into hiccup mode protecting the unit and the connected load.
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.
6) Status Signals:
“Input OK” green LED:
on = the input voltage is present and within the product specified input voltage range
off = the input voltage is not present, check wiring
“Output OK” green LED:
on = the output voltage is present and within the product specified output voltage regulation range
off = output overload, direct short circuit on the output, input voltage not present, OVT/OVP shut down or device internal failure.
“OVERLOAD” red LED:
on = output overload, direct short circuit on the output, OVT/OVP shut down or device internal failure.
off = normal operation
“DC OK” relay contact:
Contact closes when the output voltage is present and within the product specified output voltage regulation range
“LOAD” LEDs bargraph
Each LED corresponds to about 4.5A of load current, all 4 LEDs are on when the output current exceeds about 18A
7) Redundant and parallel connection: For redundant connection, an external isolating diode must be used. Nextys OR20 or OR50 products are recommended.
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
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.
