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 the device to the factory for inspection.
Install the 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. Use ferrules for wires on the input terminals.
Unused screw terminals should be securely tightened.
The device is designed for use in 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 housing does not
provide protection against spilled liquids.
The isolation of the device is designed to withstand impulse voltages of overvoltage
category III according to IEC 60664-1.
The device is designed as Class of Protection I equipment according to IEC 61140.
Do not use without a proper PE (Protective Earth) connection.
The device is suitable to be supplied from TN, TT or IT mains networks. The continuous
voltage between the input terminals and the PE potential must not exceed 300Vac.
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 device.
•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
•Do not use with DC input voltages. Do not use with AC input voltages below 90Vac.
•Use only in standard vertical mounting orientation with the input terminals on bottom
of the unit.
•Substitution of components may impair suitability for this environment.
•Do not disconnect the device or operate the voltage adjustment 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

The device is designed for altitudes up to 5000m (16400ft). Above 2000m (6560ft) a reduction
in output current and over voltage category is required.
Keep the following installation clearances: 40mm on top, 20mm on the bottom, 5mm on the 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 32A (IEC) and 30A (UL)
without additional protection device. If an external fuse is utilized, do not use circuit breakers
smaller than 10A 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.

1This current is also available for temperatures up to +70°C with a duty cycle of 10% and/or not longer than 1 minute every 10 minutes.
2At heavy overloads (when output voltage falls below 13V), the power supply delivers continuous output current for 2s.
After this, the output is switched off for approx. 18s before a new start attempt is automatically performed. This cycle is repeated as long
as the overload exists. If the overload has been cleared, the device will operate normally. See Figure 8.3.
