Description
Specification Quick Reference
The 1606-XLSRED40 is a redundancy module which can
be used to build 1+1 and N+1 redundant systems. It is
equipped with two input channels, which can be
connected to power supplies with up to 20A output
current and one output, which can carry nominal
currents up to 40A. The module is suitable for power
supplies with constant current overload behavior as well
as any kind of “Hiccup” overload behavior.

range
Input current
The novelty of this redundancy module is the utilization
of mosfets instead of diodes for the decoupling of the
two input channels. This reduces the heat generation
and the voltage drop between input and output. The
redundancy module does not require an additional
auxiliary voltage and is self-sufficient even in case of a
short circuit across the output.
Due to the low power losses, the unit is very slender and
only requires 36mm width on the DIN rail. Large
connection terminals allow for a safe and fast
installation with a large international approval package.
This unit is suitable for nearly every application.

1. Intended Use
• This redundancy module is designed for installation in an enclosure and is intended for general use such as in industrial control, office,
communication and instrumentation equipment.
• This redundancy module can be used with any type of power supply as long as the maximum ratings are not exceeded. It is suitable for power
supplies with constant current overload behavior as well as any kind of “Hiccup” overload behavior.
• Do not use this redundancy module in equipment where malfunction may cause severe personal injury or threaten human life.
• This device is designed for use in hazardous, non-hazardous, ordinary or unclassified locations.
2. Installation Requirements
•
•
•
•
This device may only be installed and put into operation by qualified personnel.
This device does not contain serviceable parts.
If damage or malfunction should occur during installation or operation, immediately turn power off and send unit to the factory for inspection.
Mount the unit on a DIN rail so that the input terminals are located on top and the output terminals on the bottom of the unit. For other
mounting orientations, see derating requirements in the present document (refer to section 17.6).
• This device is designed for convection cooling and does not require an external fan. Do not obstruct airflow and do not cover ventilation grid
(e.g. cable conduits) by more than 30%!
• Keep the following installation clearances: 40mm on top, 20mm on the bottom, 5mm on the left and right sides are recommended when the
device is loaded permanently with more than 50% of the rated power. Increase the side clearance to 15mm in case the adjacent device is a heat
source (e.g. another power supply). See section 17.3 for further information in combination with poser supplies.
SHOCK HAZARD: Do not use the power supply without proper grounding (Protective Earth). Use the terminal on the input
block for earth connection and not one of the screws on the housing.
- Turn power off before working on the device. Protect against inadvertent re-powering
- Make sure that the wiring is correct by following all local and national codes
- Do not modify or repair the unit
- Do not open the unit as high voltages are present inside
- Use caution to prevent any foreign objects from entering 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 surfaces may cause burns.
WARNING: EXPLOSION HAZARDS!
Substitution of components may impair suitability for this environment. Do not disconnect the unit 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 meets the requirements of the EN 60079-15:2010.
Notes for use in hazardous location areas:
• The unit 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 and is
evaluated according to EN 60079-0:2009 and EN 60079-15:2010.
All parameters are specified at 24V, 40A output current, 26°C ambient and after a 5 minutes run-in time, unless noted otherwise.

5. Lifetime Expectancy and MTBF
The redundancy module has two input channels which are completely independent from each other. Each control
circuit, auxiliary voltage source, or other circuitry in the module are designed separately for each input. The dual input
redundancy module can be considered as two single redundancy modules combined together in one housing. The only
common point is the circuit trace that ties the two separate circuits together at the output.
The MTBF figures below are for the entire dual input module. If the MTBF number of only one path is needed, simply
double the value from the table.

The Lifetime expectancy shown in the table indicates the minimum operating hours (service life) and is determined by the lifetime
expectancy of the built-in electrolytic capacitors. Lifetime expectancy is specified in operational hours and is calculated according to the
capacitor’s manufacturer specification. The manufacturer of the electrolytic capacitors only guarantees a maximum life of up to 15 years
(131 400h). Any number exceeding this value is a calculated theoretical lifetime which can be used to compare devices.
**) MTBF stands for Mean Time Between Failure, which is calculated according to statistical device failures, and indicates reliability of a
device. It is the statistical representation of the likelihood of a unit to fail and does not necessarily represent the life of a product.
The MTBF figure is a statistical representation of the likelihood of a device to fail. A MTBF figure of e.g. 1 000 000h means that
statistically one unit will fail every 100 hours if 10 000 units are installed in the field. However, it can not be determined if the failed unit
has been running for 50 000h or only for 100h.

b) Use appropriate copper cables that are designed for minimum operating temperatures of:
60°C for ambient up to 45°C and
75°C for ambient up to 60°C and
90°C for ambient up to 70°C minimum.
c) Follow national installation codes and installation regulations!
d) Ensure that all strands of a stranded wire enter the terminal connection!
e) Screws of unused terminal compartments should be securely tightened.
f) Ferrules are allowed.
g) Do not connect or disconnect the wires from the terminals below -25°C (-13°F).

Type and factory tests are conducted by the manufacturer. Field tests may be conducted in the field using the
appropriate test equipment which applies the voltage with a slow ramp (2s up and 2s down). Connect input/output
terminals together before conducting the test.
When testing, set the cut-off current settings to the value in the table below.

17. Application Notes
17.1. Recommendations for Redundancy
Recommendations for the configuration of redundant power systems:
-
Use separate input fuses for each power supply.
-
Use three-phase power supplies to gain functional safety if one phase fails.
-
When single-phase power supplies are utilized connect them to different phases or mains circuits if possible.
-
Set the power supply in “Parallel-Use” mode if this feature is available
-
It is desirable to set the output voltages of all power supplies to the same value.
17.2. Inductive and Capacitive Loads
The unit is designed to supply any kind of load, including unlimited capacitive and inductive loads.
17.3. Lateral Installation Clearances
The minimum clearance recommendations are defined in section 2.
Normally, the following installation clearance are recommended: 40mm on top, 20mm on the bottom, 5mm on the
left and right sides when the device is loaded permanently with more than 50% of the rated power. Increase this
clearance to 15mm in case the adjacent device is a heat source (e.g. another power supply).
The clearance between the power supplies and the redundancy module can be reduced to zero under the following
conditions:
-
1+1 redundancy application with maximum 20A output current.
-
The power supplies are from the XLS family.
-
The redundancy module is placed between the two power supplies.
-
The output voltage is set to the same level on both power supplies.

17.6. Mounting Orientations
Mounting orientations other than input terminals on the bottom and output on the top require a reduction in
continuous output power or a limitation in the maximum allowed ambient temperature. The amount of reduction
influences the lifetime expectancy of the power supply. Therefore, two different derating curves for continuous
operation can be found below:
Curve A1
Curve A2
Recommended output current.
Max allowed output current (results in approximately half the lifetime expectancy of A1).
