3. WORKING
3-1 Safety instructions
DANGER: HAZARD OF ELECTRIC SHOCK, EXPLOSION OR ARC FLASH
Only qualified persons should ensure the installation, use, repair and maintenance
of electrical equipment.

Before installation or maintenance work requiring the opening of access doors,
disconnect all power supplies to the equipment and connected equipment. The
main circuit breaker must be opened and locked to prevent it from closing unintentionally.
Check that the power supply is not present according to the indications with a
correctly set voltage measuring device.

This equipment and associated products must only be connected to the power
supply within the specified voltage range.
Before switching the power back on, check that the device is properly earthed and
that all protections, wires, cables or other are correctly fixed.
Install and use this product only in non-hazardous areas.
Failure to follow these instructions may result in death or serious injury.
WARNING

This equipment must not be accessible during normal operation and must be used
in a safe place, in accordance with the temperature and humidity specifications in
STATUS indicator the product instructions.
Install and use in a restricted access location with key or tool locks. (electrical
equipment box or in closed box, ...).
Fine voltage
In order not to compromise the safety of the equipment and associated products,
adjustment
you must connect it to earth.
The common mode voltage between the earth and the outputs must not exceed 50Vac.
A line circuit breaker must be included in the power supply circuit in the immediate
ON indicator :
vicinity of the device and must be easily accessible by the operator.
voltage presence
Power supply 220-240 V:
Share Bus
Power supply 380-400 V:

Follow the installation and wiring instructions in this document; failure to do so
may result in death, serious injury or property damage.
If the equipment is used in an unspecified or unauthorized manner, the protection
provided by the equipment may be compromised.
Do not exceed the maximum output power or current listed in the product's
instruction manual.
Use wires that can withstand temperatures of at least 75°C.
For good convection, this appliance must be installed vertically. It is necessary to
maintain a 50 mm clearance on all sides and not to obstruct the openings.
RISK OF BURNS
Avoid unprotected contact with hot surfaces; allow the product to cool for 30
minutes before touching it.
3-2 Mounting
Mounting by CLIP on the profiled 35x15 mm or 35x7,5 mm (DIN rails EN 50022).
- Engage the hooks on the top of the rail.
- Push the power supply against the rail, in order to lock the
hook (push it back if necessary).
To take it off :
- Introduce a screwdriver into the part of the hook located
under the power supply.
- Push it toward the bottom.
- Take it off, rocking it toward the top.

dangerous parts under voltage and can lead to death or serious wounds.
° C
3 1 4 0 Respect the connections of the main and of the output indicated on screenprint.
The use of weak section or important length wire leads to a degradation of the characteristics.
One meter of 2.5 mm2 wire with a 10 amps current makes the voltage fall of approximately
80 mV. It it thus advised not to go under this section.
3-3-1 Normal operation
The ALE2412 is delivered adjusted at 24 V ±0.5%.
After having plugged the wires on the load and on the main, close the circuit breaker, the
power supply starts after 3 seconds. The green light switches on, the voltage is in the output.
3-3-2 Operation with a voltage output different from 24 V
- Plug to the main, close the circuit breaker, the power supply starts after 3 seconds.
The green light switches on, the voltage is in the output.
- Connect a voltmeter on the output and adjust the desired voltage with the adjustement.
- Disconnect the voltmeter and open the circuit breaker.
Single-phase, Single-pole + Neutral 3A, curve C ;
two-phase, two-pole 3A, curve C
Two-phase, , two-pole 400V~ 2A, curve C.
- Connect the load.
- Close the circuit breaker, the power supply starts after 3 seconds. The green light
switches on, the desired voltage is in the output.
3-3-3 Paralleling
ALE2412 has a load share controller "Share
Bus" which manages the share of the current
between an unlimited number of power sup-
plies of the same type.
Precautions
In order to easier the wiring, we advise you
not to exceed 4 power supplies on the same rail.
Let a 50 mm space between each for a good and natural
cooling. Each power supply must have its own circuit
breaker. Before any connections, check that the mains is
not in the wire. The power supplies are delivered adjusted
at 24 V ±0.5%, so they can be put in parallel directly. On the
other hand, if you need a different voltage value, you will have to do the adjustement
following § 3-2-2 with a max. variation of 3%, so 0.7 V between the power supplies.
The output voltage value once connected in parallel will be given by the one with the highest
voltage. The recommended wiring for paralleling is the following :
- link the "Share bus" (0.5 mm² wire) between the power supplies (2 points connector).
- link both "+" of each power supply with wires of the same lenght and same section
(2.5 mm²) to a terminal block.
- link both "-" of each power supplies with wires of the same lenght and same section
(2.5 mm²) to a terminal block.
- link "+" and "-" of the load to the terminal block with wires of appropriate cross section.
3-3-4 Contact dry «power status»
Terminal will provide information on power status.
Once the equipment works and that the voltage output is greater than 20V, the normally open
contact closes and opens normally closed. These contacts are completely isolated from the
rest. The voltage-current values do not exceed the terminal are 250Vac - 1A.
4. OPERATION
ALE2412 is a switching and regulated DC power supply with a floating output (potential free),
protected against short-circuits. If the requested current is superior to the one the ALE2412
can supply, a current limitation starts and the output voltage decreases.
Indicator: Green LED : "ON" the output voltage is present.
Red LED : "STATUS" the protection against overheat is active or a
regulation defect limits the output voltage at 34 V.
5. MAINTENANCE
No particular maintenance is required for this instrument.
Avoid dust, humidity, shocks : your instrument will be grateful to you for that.
If indicator does not light up when plugging, check :
- the connection to the main input voltage and the Main voltage presence.
if red LED lights up, check :
- the output fuse (auto clip 20 A)
If the problem remains, please return this power supply to our after sales service.
