ENML30.102 Installation Manual

Product Description
The ML30.102 is a DIN-rail mountable single-phase-input power supply, which provides a floating,stabilized and galvanically separated SELV/PELV output voltage.
The output of the device fulfils the requirements for a limited power source acc. to NEC Class 2.
The ripple and noise voltage on the output is very little and is suitable to supply 4-20mA control
loops.

Intended Use
This device is designed for installation in an enclosure and is intended for commercial use, such as
in industrial control, process control, monitoring, measurement equipment or the like. Do not use thisdevice in equipment, where malfunctioning may cause severe personal injury or threaten human life
without additional appropriate safety devices, that are suited for the end-application.
If this device is used in a manner outside of its specification, the protection provided by the device
may be impaired.

Installation Instructions
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 thedevice. 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.
The device is designed for pollution degree 2 areas in controlled environments. No condensation orfrost is allowed.
The housing of the device provides a degree of protection of IP20. The housing does not provide
protection against spilled liquids.
The device is designed for overvoltage category II zones.
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 and IT mains networks. The continuous voltage
between the input terminals and the PE potential must not exceed 264Vac.
The input can also be powered from batteries or similar DC sources. The continuous voltage
between the supply voltage and the PE/ground potential must not exceed 375Vdc.
A disconnecting means shall be provided for the input of the device.
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 2000m (6560ft).
Keep the following minimum installation clearances: 40mm on top, 20mm on the bottom, 0mm left
and right side. Increase the 0mm to 15mm in case the adjacent device is a heat source.
The device is designed, tested and approved for branch circuits up to 16A (IEC) or 15A (UL) without
additional protection device. If an external fuse is utilized, do not use circuit breakers smaller than
10A B- or 6A 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 thesame 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.
Substitution of components may impair suitability for this environment.
Do not disconnect the device or operate the voltage adjustment unless power has been switched offor the area is known to be non-hazardous.

Functional Description
The output is electronically protected against no-load, overload and short circuit and can supply any
kind of loads, including inductive and capacitive loads.
Do not apply return voltages from the load to the output terminals higher than 25V.
A range selection can be done with the jumper on the output terminal block. An inserted jumper sets
the output voltage to 12V. An open connection allows an adjustment between 10 and 12V.
The green DC-OK LED reports a voltage on the output terminals above 6V.
Devices can be paralleled to increase the output power. The ambient temperature is not allowed to
exceed +45°C. The output voltage shall be adjusted to the same value (±100mV) with the same loadconditions on all devices, or the devices can be left with the factory settings. If more than threedevices are connected in parallel, a diode, fuse or circuit breaker with a rating of 4A or 6A isrequired on each output.
Same devices can be connected in series for higher output voltages. It is allowed to connect as
many outputs 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 18V. The
output shuts down and automatically attempts to restart.
