Install device in an enclosure providing protection against electrical, echanical and fire hazards. Install the device onto a
DIN rail according to EN 60715 with the input ter inals on the botto of the device.
Make sure that the wiring is correct by following all local and national codes. Use appropriate copper cables that are
designed for a ini u operating te perature of +60°C for a bient te peratures up to +45°C, +75°C for a bient
te peratures up to +60°C and +90°C for a bient te peratures up to +70°C. Ensure that all strands of a stranded wire enter
the ter inal connection. Unused screw ter inals should be securely tightened.
The device is designed for pollution degree 2 areas in controlled environ ents. 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

6. Output
The output provides a SELV/PELV/ES1 rated voltage, which is galvanically isolated fro the input voltage. The output is
electronically protected against no-load, overload and short circuit. In case of a protection event, audible noise ay occur.
The output is designed to supply any kind of loads, including inductive and capacitive loads. Capacitive loads should not
be larger than 4 000μF with 3.8A or 5 000μF with 1.9A additional resistive load.
At heavy overloads (when output voltage falls below 14V), the device delivers continuous output current for 20 s. After
this, the output is switched off for approx. 160 s before a new start atte pt is auto atically perfor ed. This cycle is
repeated as long as the overload exists.
If the overload has been cleared, the device will operate nor ally.

The hold-up ti e is the ti e during which a device’s output voltage re ains within specification following the loss of input
power. The hold-up ti e is output load dependent. At no load, the hold-up ti e can be up to several seconds. The green

9. Lifeti e Expectancy
The Lifeti e expectancy shown in the table indicates the ini u operating hours (service life) and is deter ined by
the lifeti e expectancy of the built-in electrolytic capacitors. Lifeti e expectancy is specified in operational hours and is
calculated according to the capacitor’s anufacturer specification.
Please note: The anufacturer of the electrolytic capacitors only guarantees a axi u life of up to 15 years (131 400h).
Any nu ber exceeding this value is a calculated theoretical lifeti e which can be used to co pare devices.

10. MTBF
MTBF stands for Mean Ti e 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 eans
that statistically one unit will fail every 100 hours if 10 000 units are installed in the field. However, it cannot be deter ined
if the failed unit has been running for 50 000h or only for 100h.
For these types of units the MTTF (Mean Ti e To Failure) value is the sa e value as the MTBF value.

17. Dielectric Strength
The output voltage is floating and has no oh ic connection to the ground.
It is reco ended that either the (+) pole or the (–) pole shall be connected to the protective earth syste . This helps to
avoid situations in which a load starts unexpectedly or can not be switched off when unnoticed earth faults occur.
Type and routine tests are conducted by the anufacturer. Field tests ay be conducted in the field using the appropriate
test equip ent which applies the voltage with a slow ra p (2s up and 2s down). Connect all phase-ter inals together
as well as all output poles before conducting the test. When testing, set the cut-off current settings to the value in the
table below.

21. Application Notes
21.1. CHARGING OF BATTERIES
Do not use the power supply to charge batteries.
21.2. SERIES OPERATION
Power supplies of the sa e type can be connected in series for higher output
voltages. It is possible to connect as any units in series as needed, providing the
su of the output voltage does not exceed 150Vdc. Voltages with a potential
above 60Vdc ust be installed with a protection against touching.
Avoid return voltage (e.g. fro a decelerating otor or battery) which is applied
to the output ter inals.
Keep an installation clearance of 15 (left / right) between two power supplies
and avoid installing the power supplies on top of each other.
Do not use power supplies in series in ounting orientations other than the
standard ounting orientation.
Pay attention that leakage current, EMI, inrush current, har onics will increase
when using ultiple power supplies.
21.3. PARALLEL USE TO INCREASE OUTPUT POWER
Do not use this devices in parallel to increase the output power.
21.4. PARALLEL USE FOR 1+1 REDUNDANCY
Devices can be paralleled for 1+1 redundancy to gain higher syste availability. Redundant syste s require a certain
a ount of extra power to support the load in case one device fails. The si plest way is to put two devices in parallel. This
is called a 1+1 redundancy. In case one device fails, the other one is auto atically able to support the load current without
any interruption. It is essential to use a redundancy odule to decouple devices fro each other. This prevents that the
defective unit beco es a load for the other device and the output voltage cannot be aintained any ore.
This device does not incorporate eans to report a defective or non functional power supply. Since this is essential for
redundant syste s, chose a redundancy odule which onitors and reports an insufficient input voltage or use a power
supply, which has a DC-OK signal included.
21.5. TWO PHASE OPERATION
The power supply can also be operated on two phases of a three-phase-syste .
Such a phase-to-phase connection is allowed as long as the supplying voltage is
below 240V+10%.
Ensure that the wire, which is connected to the N-ter inal, is appropriately fused.

21.6. USE IN A TIGHTLY SEALED ENCLOSURE
When the power supply is installed in a tightly sealed enclosure, the te perature inside the enclosure will be higher than
outside. In such situations, the inside te perature defines the a bient te perature for the power supply.
The power supply is placed in the iddle of the box, no other heat producing ite s are inside the box. The te perature
sensor inside the box is placed in the iddle of the right side of the power supply with a distance of 1c . The following
