oggetti metallici.
Non far funzionare l'apparecchio in un ambiente umido. Non far funzionare l'apparecchio
in un ambiente soggetto alla formazione di condensa o di rugiada.
Non toccare quando acceso e subito dopo lo spegnimento. La superficie calda puòcausare scottature.

A não observância ou o incumprimento dos pontos a seguir
mencionados, poderá causar uma descarga elétrica, incêndios,acidentes graves ou morte:
Antes de trabalhos de instalação, manutenção ou modificação, desligue a tensão dealimentação, protegendo-a contra uma nova ligação involuntária.
Não efectue nenhuma modificação ou tentativa de reparação no aparelho. Quando
necessário contacte o seu distribuidor. Não abra o aparelho.
Proteger a fonte de alimentação contra a introdução inadvertida de corpos metálicos, comopor ex., clipes ou outras peças de metal.

ENQTD20.241 Installation Manual

Product Description
The QTD20.241 is a DIN-rail mountable DC/DC converter, which provides a floating, stabilized andgalvanically separated SELV/PELV output voltage.

Intended Use
This device is designed for installation in an enclosure and is intended for commercial use, such as inindustrial control, process control, monitoring and measurement equipment or the like.
This device is optimized to operate from the intermediate bus of a drive system. It can cope with theEMI disturbances on such busses.
Do not use this device in equipment, where malfunctioning may cause severe personal injury orthreaten human life without additional appropriate safety devices, that are suited for the endapplication.
If this device is used in a manner outside of its specification, the protection provided by the device may
be impaired.

Installation Instructions
Install device in an enclosure providing protection against electrical, mechanical and fire hazards.
Install the device onto a DIN-rail according to EN 60715 with the input terminals on the bottom of thedevice. Other mounting orientations require a reduction in output current.
Make sure that the wiring is correct by following all local and national codes. Use appropriate copper
cables that are designed for a minimum operating temperature of 60°C for ambient temperatures up to+45°C, 75°C for ambient temperatures up to +60°C and 90°C for ambient temperatures up to +70°C.
Ensure that all strands of a stranded wire enter the terminal connection. Use ferrules for wires on theinput terminals.
The device is designed for pollution degree 2 areas in controlled environments. No condensation orfrost is allowed.
The enclosure of the device provides a degree of protection of IP20. The enclosure does not provide
protection against spilled liquids.
The isolation of the devices is designed to withstand impulse voltages up to 4kV according to IEC
60664-1.
The device is designed as “Class of Protection I” equipment according to IEC 61140. Do not use
without a proper PE (Protective Earth) connection.
The device is designed to be supplied from a DC input voltage derived from a 3-phase mains networkby means of a B6 bridge rectifier. The device is not designed to be used on corner grounded deltasystems. Follow the wiring scheme option 1 shown in this document.
The input can also be supplied by batteries or similar DC sources. Since the continuous voltage
between the input voltage and the PE/earth potential must not exceed 440V r.m.s., the input voltage
must be grounded at about half the supply voltage as shown in option 2 in the wiring scheme drawing.
Do not ground the positive or negative input voltage pole.
Check for correct input polarity. The device will not operate when the voltage is reversed.
A disconnecting means shall be provided for the input of the device.
The device is designed for convection cooling and does not require an external fan. Do not obstruct
airflow and do not cover ventilation grid!
The device is designed for altitudes up to 5000m (16400ft).
Keep the following minimum installation clearances: 40mm on top, 20mm on the bottom, 5mm left andright side. Increase the 5mm to 15mm in case the adjacent device is a heat source. When the device
is permanently loaded with less than 50%, the 5mm can be reduced to zero.
The device is designed, tested and approved for branch circuits up to 16A (IEC) and 15A (UL) without
additional protection device. If an external fuse is utilized, do not use circuit breakers smaller than 6A
B- or 3A C-Characteristic to avoid a nuisance tripping of the circuit breaker.
The maximum surrounding air temperature is +70°C (+158°F). The operational temperature is thesame as the ambient or surrounding air temperature and is defined 2cm below the device.
The device is designed to operate in areas between 5% and 95% relative humidity.

Functional Description
The output is electronically protected against no-load, overload and short circuit and can supply any
kind of loads, including unlimited inductive and capacitive loads.
Do not apply return voltages from the load to the output terminals higher than 34V.
The output voltage can be adjusted with a small flat-blade screwdriver behind the flap on the front.
The green DC OK LED reports an output voltage above 90% of the adjusted voltage of a runningdevice.
The DC OK relay monitors the output voltage and the contact is closed when the DC-OK LED is on.
Contact ratings: 60Vdc 0.3A, 30Vdc 1A, 30Vac 0.5A for resistive loads.
The red overload LED is on when the output voltage falls below 90% of the adjusted value or in caseof a short circuit in the output or too high temperature. Input voltage is required.
The device is equipped with an over-temperature protection. In case of a high temperature, the output
shuts down and starts automatically again after cooling off.
Devices can be paralleled to increase the output power. The ambient temperature is not allowed toexceed +60°C. The output voltage shall be adjusted to the same value (±100mV) with the same loadconditions on all devices, or the devices can be left with the factory settings. If more than threedevices are connected in parallel, a diode, fuse or circuit breaker with a rating of 25A is required oneach output.
Same devices can be connected in series for higher output voltages. It is allowed to connect as many
devices in series as needed, providing the sum of the output voltage does not exceed 150Vdc.
In case of an internal defect, a redundant circuit limits the maximum output voltage to 35V. The output
shuts down and automatically attempts to restart.
