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 device in an enclosure providing protection against electrical, mechanical
and fire hazards.
Install the device onto a DIN-rail according to EN 60715 with the input 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 allowed.
The enclosure of the device provides a degree of protection of IP20.
The input can be powered from batteries or similar DC sources. The voltage between
the input terminals and ground must not exceed 60Vdc continuously. The ripple voltage
in the low frequency range between 50Hz and 10kHz must be negligible when used
in marine applications.
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 for correct input polarity. The device will not operate when the voltage is reversed.
A disconnecting means shall be provided for the input of the device.
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 this document for use above 2000m (6560ft).
Warning!
Risk of electrical shock, fire, personal injury or death.
•Turn power off before working on the device. Protect against inadvertent re-powering.
•Do not modify or repair the unit.
•Do not open the unit as high voltages may 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 surface may cause burns.
Note
Observe the safety information in the instruction manual and in chapter 20.

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.
The device is designed, tested and approved for branch circuits up to 50A without additional
protection device. If an external fuse is utilized, do not use circuit breakers smaller
than 20A B- or C-Characteristic to avoid a nuisance tripping of the circuit breaker.
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.

Requirements for the Supplying Source
In certain circumstances, the input filter of the DC/DC converter can show a resonant effect
which is caused by the supplying network. Especially when additional external input filters
are utilized, a superimposed AC voltage can be generated on the input terminals
of the DC/DC converter which might cause a malfunction of the unit.
Therefore, additional input filters are not recommended. To avoid the resonant effects,
the minimal resistance of the supplying network which depends on the inductance of the input
network, shall be above the boundary curve in Figure 5.4.

Input Inrush Current
6 Input Inrush Current
An active inrush limitation circuit (inrush limiting NTC resistor which is bypassed
by a MOSFET) limits the input inrush current after turn-on of the input voltage.
The charging current into EMI suppression capacitors is disregarded in the first microseconds
after switch-on.

Soft-Start Feature
2021-11
13
7 Soft-Start Feature
After the DC/DC converter is turned on, the internal output current rises slowly to its nominal
value. This method charges the output capacitors (internal and external capacitors) slowly
and avoids high input currents during turn-on.
High input currents can produce a high voltage drop on the input wiring (especially with long
and thin cables) which reduces the terminal voltage on the DC/DC converter. If the terminal
voltage is below the shut-down voltage, the DC/DC converter will turn-off and will make a new
start-up attempt. This effect is avoided with the integrated soft-start function.
Note
This function increases the rise time of the output voltage by a small amount.

Hold-Up Time
9 Hold-Up Time
The input side of the DC/DC converter is equipped with a bulk capacitor which keeps
the output voltage alive for a certain period of time when the input voltage dips or is removed.
The bulk capacitor can be discharged by loading the DC/DC converter on the output side
or through a load which is parallel to the input. There is no protection in the DC/DC converter
which prevents current from flowing back to the input terminals. If prevention is needed,
an external diode should be used.
At no load, the hold-up time can be up to several seconds. The green DC-ok lamp is also
on during this time.
