DC 24V A figure displayed with the AC or DC before the value represents
a nominal voltage with standard tolerances (usually ±15%) included.
E.g.: DC 12V describes a 12V battery disregarding whether it is full

24Vdc A figure with the unit (Vdc) at the end is a momentary figure without
any additional tolerances included.

shall A key word indicating a mandatory requirement.
should A key word indicating flexibility of choice with a strongly preferred
implementation.
1+1 Redundancy Use of two identical power supplies in parallel to provide continued
operation following most failures in a single power supply.
The two power supply outputs should be isolated from each other
by utilizing diodes or other switching arrangements.
E.g. two 10A power supplies are needed to achieve a 10A redundant
system.

3 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.
Function
The device is a redundancy module for building redundant power supply systems.
The device is equipped with 2 inputs and 1 output. Power supplies with an output current
of up to 24 A and one output can be connected to the inputs. The power supplies can transmit
a rated current of up to 20 A.
The both inputs are decoupled by MOSFETs. This reduces heat generation and voltage drop
between input and output.
The device is mounted on a 35 mm DIN mounting rail according to EN 60715.
Reference Conditions
All parameters are typical values specified at 24V, 20A output current, 25°C ambient
and after a 5 minutes run-in time unless otherwise noted.

Installation Instructions
4 Installation Instructions
This device may only be installed and put into operation by qualified personnel.
This device does not contain serviceable parts. The tripping of an internal fuse is caused
by an internal defect.
If damage or malfunction should occur during installation or operation, immediately turn
power off and send unit to the factory for inspection.
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.
Warning!
Risk of electrical shock, fire, personal injury or death.
•Turn power off before working on the device and protect against inadvertent re-powering.
•Do not open, modify or repair the device.
•Use caution to prevent any foreign objects from entering into the housing.
•Do not use in wet locations or in areas where moisture or condensation can be expected.
•Do not touch during power-on, and immediately after power-off.
Hot surface may cause burns.
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 fulfills the requirements of the EN 60079-0.
Note
If you use the device in hazardous areas, observe the safety information in the instruction
manual and in chapter 19.

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.
