EN YR20.246 Installation Manual
Product Description
The YR20.246 is a redundancy module for building redundant power supply systems. It is equipped
with two input channels and one output. The two inputs are decoupled by MOSFET technology.
The device is equipped with an automated load sharing feature, which can compensate a small
voltage imbalance between the power supplies connected to the inputs in order to achieve an even
current share. It also monitors the function of the redundancy circuitry and provides a signal in case of
a failure or a high output current, which could prevent redundancy if one power supply fails.
Intended Use
This device is designed for installation in an enclosure and is intended for commercial use, such as in
industrial control, process control, monitoring and measurement equipment or the like. Do not use this
device 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 as
well 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 ground
failure. 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 the
device. 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 or
frost 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 to
maintain 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 ground
can 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 product
datasheet for use above 2000m (6560ft).
Keep the following minimum installation clearances: 40mm on top, 20mm on the bottom, 5mm left and
right 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 the
same 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.
To ensure a proper load share function, ensure that the wiring size and length between the two power
supplies and the redundancy module is identical.
Installation Instructions for Hazardous Location Areas
The device is suitable for use in Class I Division 2 Groups A, B, C, D locations and for use in Group II
Category 3 (Zone 2) environments.
Hazardous Location classification: ATEX: EPS 11 ATEX 1 312 X, II 3G EX ec nC IIC T4 Gc
WARNING EXPLOSION HAZARDS!
Substitution of components may impair suitability for this environment.
Do not disconnect the device unless power has been switched off or the area is known to be non-
hazardous.
A suitable enclosure must be provided for the end product which has a minimum protection of IP54
and fulfils the requirements of the EN 60079-0.
Functional Description
The device can supply any kind of loads, including unlimited capacitive and inductive loads.
Do not apply return voltages from the load to the output of the redundancy module higher than 40Vdc.
Automated load share function and “Load Share OK” relay contact.
When installing the devices, adjust the power supply voltages that only the green LED in the middle is
on (area 1 of the diagram). Area 2 indicates that the redundancy module operates within the
automated load share range and area 3 indicates that load sharing is not possible, which is also
reported through the “Load Share OK” relay contact (contact is open).
Selector for output current warning threshold and “Output current < IN“ LED
If the output current increases, e. g. due to additionally loads, and exceeds the nominal current of one
power supply, redundancy is no longer guaranteed. Therefore, the output current is monitored and is
reported through a LED (Output current < IN) and a relay contact (Redundancy OK) when exceeding
the predefined value.
Set the selector to 5A used with two 5A or 10A when used with two 10A power supplies (1+1
redundancy). Set the selector to 20A for n+1 redundant systems. With a 20A setting, redundancy
cannot be checked by the redundancy module.
Relay contact “Redundancy OK”
The relay contact is closed when no redundancy errors are detected. The relay contact is
synchronized with the “Redundancy OK” LED. The contact is open when one or both input voltages
are below 22Vdc or above 30Vdc. It is also open when the output current is higher than the adjusted
value of the output current threshold setting, or an internal defect of the module is detected.
