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 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 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.
The device is designed to operate in areas between 5% and 95% relative humidity.
Installation Instructions for Hazardous Location Areas
The device 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.
Classification: ATEX: EPS 17 ATEX 1 089 X, II 3G EX ec nC IIC T4 Gc / IECEx EPS 19.0103X
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.
The equipment shall be installed in an enclosure that provides a degree of protection not less than IP54 in accordance with
EN 60079-7 or EN 60079-15.
Functional Description
The output is electronically protected against no-load, overload and short circuit and can supply any kind of loads, including
unlimited inductive and capacitive loads. If capacitors with a capacitance >0.25F are connected, the unit might charge the
capacitor in an intermittent mode.
Do not apply return voltages from the load to the output higher than 63V.
The output voltage can be adjusted with a small flat-blade screwdriver on the front of the unit.
The green DC-OK LED reports an output voltage above 90% of the adjusted voltage of a running device.
The DC-OK relay monitors the output voltage and the contact is closed when the DC-OK LED is on. Contact ratings: 60Vdc
0.3A, 30Vdc 1A, 30Vac 0.5A for resistive loads.
The device is equipped with an over-temperature protection. In case of a high temperature, the output shuts down and starts
automatically again after cooling off.
At heavy overloads (when output voltage falls below 26V), the device delivers continuous output current for 2s. After this, the
output is switched off for 18s before a new start attempt is automatically performed. This cycle is repeated as long as the
overload exists.
Devices can be paralleled to increase the output power. The ambient temperature is not allowed to exceed 60°C. The output
voltage of all devices shall be adjusted to the same value (±100mV) in “Single Use” mode with the same load conditions on
all units, or the units can be left with the factory settings. After the adjustments, set the unit to “Parallel Use” mode, in order to
achieve load sharing. The “Parallel Use” mode regulates the output voltage in such a manner that the voltage at no load is
approx. 4% higher than at nominal load. Energize all units at the same time. It also might be necessary to cycle the input
power (turn-off for at least five seconds), if the output was in overload or short circuit. If more than three devices are
connected in parallel, a diode, fuse or circuit breaker with a rating of 16A or 20A is required on each output.
Same devices can be connected in series for higher output voltages. It is allowed to connect as many devices in series as
needed, providing the sum of the output voltage does not exceed 150Vdc.
In case of an internal defect, a redundant circuit limits the maximum output voltage to 60V. The output shuts down and
performs three restart attempts. If the failure continues, the output shuts down. Cycle input power to reset.
