Application
The primary switch mode power supply is specifically designed with integrated data decoupling for the supply of ASinterface systems. It operates at two selectable input voltage ranges and can be used worldwide, within compact
dimensions. The easy-to-set front-face jumper allows the assignment of new ID addresses to slaves by means of an
external infrared programming unit without disconnecting them from the AS-Interface cable.
Up to 62 binary I/O devices can be connected and supplied according to the AS-interface bus technology with a single
two-conductor cable. The communication signals are modulated onto the slaves’ DC supply voltage of the AS-interface
system, which therefore requires a specific power supply with integrated data decoupling.
Operating mode
By means of the input voltage selector the input voltage can either be set to 115 V AC or 230 V AC. The front-face
jumper allows the configuration of the operation mode of the power supply, i.e. “1-2 COMMUNICATION MODE” or “2-3
IR ADDRESSING MODE” to enable communication control and supply of AS-interface slaves or to interrupt the data
communication for the assignment of new ID addresses to participants by means of an external infrared programming unit.
The green LED “AS-I OK” is on during normal operation, i.e. when the output voltage exceeds 30 V DC, and is off at
overload.
The red LED “IR ADDRESSING ON” is on when data communication has been interrupted by means of the jumper.

Installation
The device must be installed by qualified persons only and in accordance with the specific national regulations (e.g. VDE,
etc.). The devices are maintenance-free chassis-mounted units.
Before installation
DANGER!
Components with high stored energy and circuits with high voltage
Danger to be electrocuted!
Disconnect the system from the supply network and protect against switching on before any
installation, maintenance or modification work.
Do not introduce any objects into the unit and do not open the unit.
Ensure that the service personnel is protected against inadvertent contact with parts carrying energy.
Mounting
2CDC273001F0012
The switch mode power supply can be snapped on a DIN rail (TH 35-15 or TH 35-7.5 according to IEC/EN 60715) as
shown in the accompanying picture. For that the device is set with its mounting rail slide on the upper edge of the mounting
rail and locked by lifting it downwards.
click
Demounting
2CDC273002F0012
Remove the switch mode power supply as shown in the accompanying picture. For that the latching lever is pulled
downwards by means of the screwdriver. Alternatively the upperside of the latching lever can be pressed to release the
device. Then in both cases the device can be unhinged from the mounting rail edge and removed.

Mounting position
The devices have to be mounted horizontally with the input terminals on the bottom. In order to ensure a sufficient
convection, the minimum distance to other modules should not be less than 15 mm (0.59 in) in vertical and 25 mm (0.98 in)
horizontal direction.

Preparations:
–
Connect to mains according to the specific national regulations.
–
Power supply cables and unit must be sufficiently fused. A disconnecting device has to be provided for the power supply
to disengage unit and supply cables from supply mains if required.
–
We recommend to choose the cable section as large as possible in order to minimize voltage drops.
–
In order to ensure sufficient air-cooling the distance to other devices has to be considered.
Instructions:
1. Connect the input terminals L and N.
2. Connect the protective earth conductor to terminal o (protection class I).
3. Provide a suitable disconnecting device (e.g. line protection switch) in the supply line acc. to IEC/EN 60950-1.
4. Rate the lines for the maximum output current (considering the short-circuit current) or provide a separate fuse protection.
The input side is protected by an internal input fuse.
5. Observe the polarity.
Connect the ‘shield’ terminal on the AS-i power supply to the machine ground so that the AS-i system is symmetrically
operated against this machine ground. This improves noise sensitivity in case of symmetrical interference on the AS-i cable.
The device is overload, short-circuit and open-circuit proof. The secondary side of the power supply unit is electrically
isolated from the input.

Operation
DANGER!
High current
Risk of electric arcs and electric shocks!
Do not modify the installation (primary and secondary side).
Intended use.
CAUTION!
Depending on the operation conditions the enclosure can become very hot
Risk of burns!
In order to ensure sufficient air-cooling the distance to other devices has to be considered.
The device is intended for use as a primary switch mode power supply for AS-interface systems. Any other usage is not
supported by the manufacturer. Other usage may impair safety and cause operational difficulties or destruction of the unit.
Service
The internal fuse is not user-replaceable. If the internal fuse blows, most probably the device is defective. In this case, an
examination of the switch mode power supply by the manufacturer is necessary.
