Il mancato rispetto delle seguenti norme puòprovocare folgorazione elettrica, incendi, gravi
incidenti e perfino la morte:
Prima di eseguire interventi di installazione, di manutenzione o di modifica scollegare latensione di rete ed adottare tutti i provvedimenti necessari per impedirne il ricollegamento
non intenzionale.
Non tentare di aprire, di modificare o di riparare da soli l'apparecchio.
Impedire la penetrazione di corpi estranei nell'apparecchio, ad esempio fermagli o altri
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.
Não usar o aparelho em ambientes húmidos. Não usar o aparelho em ambientes propensosa condensações.

YR20.242 Installation Manual

Product Description
The YR20.242 is a redundancy module for building redundant power supply systems. It is equippedwith two input channels and one output. The two inputs are decoupled by MOSFET technology.

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. Do not use thisdevice in equipment where malfunction may cause severe personal injury or threaten human life.
The redundancy module can be used with any type of power supply as long as the maximum output
current ratings are not exceeded. It is suitable for power supplies with continuous overload current aswell as any kind of intermittent (Hiccup) overload behavior.

Installation Instructions
Install the device in an enclosure providing protection against electrical, mechanical and fire hazards.
Do not ground or earth the positive output pole which could prevent redundancy in case of a groundfailure. Ground the negative output pole, when needed.
Use only power supplies with a negligible output ripple voltage in the low frequency range between
50Hz and 10kHz when used in marine applications according to the GL regulations.
Install the device onto a DIN-rail according to EN 60715 with the output 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.
Unused screw terminals should be securely tightened.
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 input must be powered from a PELV or SELV source or an “Isolated Secondary Circuit” in order tomaintain a SELV or PELV output.
Check correct input polarity. The device will not operate when input voltage is reversed.
The device is designed as “Class of Protection III” equipment according to IEC 61140.
A PE (ground) connection is not required. However, connecting the chassis ground terminal to groundcan be beneficial to gain a high EMI immunity.
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 6000m (19685ft). See additional requirements in the productdatasheet for use above 2000m (6560ft).
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. Under special
circumstances clearances can be reduced. See details in the product datasheet.
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.
