Product Description
The 1606-XLERED20Y SER B 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.
If this device is used in a manner outside of its specification, the protection provided by the device may be impaired.
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 enclosure does not provide protection against
spilled liquids.
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 5000m (16400ft). Above 2000m (6560ft) a reduction in output current is required.
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.
Classification: ATEX: EPS 11 ATEX 1 312 X, II 3G EX ec nC IIC T4 Gc / IECEx EPS 15.0074X
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.
The equipment shall be installed in an enclosure that provides a degree of protection not less than IP54 in accordance with
EN 60079-7 or EN 60079-15.
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 when used with two 5A power supplies or set it to 10A when used with two 10A power supplies in a
1+1 redundancy configuration. Set the selector to 20A for n+1 redundant systems. With a 20A setting, redundancy failures
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.
