EN AC1257 Installation Manual

Product Description

The AC1257 is a DIN-rail mountable DC/DC converter, which provides network power for the AS-

Interface® system. The AS-Interface® system is a field bus technology, where power and data are

provided by the same single two-conductor wire. Therefore, special DC/DC converters with an

integrated data-decoupling circuit are required to prevent the modulated signal voltage on the AS-

Interface® bus from being corrupted.

Intended Use

This device is designed for installation in an enclosure and is intended for commercial use to supply

power to AS-Interface® network systems.

Do not use this device 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.

When operating without AS-Interface structure (e.g. in a laboratory test), connect a 470μF/35V

capacitor between AS-Interface + and AS-Interface – terminals to avoid output voltage oscillations.

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 the

device.

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. Unused screw terminals

should be securely tightened.

The device is designed for 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 devices is designed to withstand impulse voltages up to 1.5kV according to IEC

60664-1.

The input can be powered from batteries or similar DC sources. The continuous voltage between the

supply voltage and the PE/ground potential must not exceed 60Vdc. The input must be powered from

a PELV or SELV source or an "Isolated Secondary Circuit" in order to maintain a SELV or PELV

output.

Check for correct input polarity. The device will not operate when the voltage is reversed.

A disconnecting means shall be provided for the input of the device.

The device is designed as “Class of Protection III” equipment according to IEC 61140. A PE (ground)

connection is not required. However, connecting the chassis ground terminal to ground can be

beneficial to gain a high EMI immunity.

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 5000m (16400ft). Above 2000m (6560ft) a reduction in

output current 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 50A without additional protection

device. If an external fuse is utilized, do not use circuit breakers smaller than 10A B- or 8A 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 10% and 90% relative humidity.

Functional Description

The output is electronically protected against no-load, overload and short circuit.

The green AS-i-OK LED reports a nominal output voltage of a running device. The LED is off as soon

as the unit is in overload mode.

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.

Do not parallel devices for higher output currents.

Do not connect outputs of devices in a series connection for higher output voltages.

In case of an internal defect, a redundant circuit limits the maximum output voltage to 36V. The output

shuts down and automatically attempts to restart.
