Analogue Input AE/S 4.2 makes an output voltage U
available to supply the sensors. It should be ensured that the
maximum output current of 300 mA is not exceeded.
Analogue Input is a DIN rail mounted device for integration into distribution
boards by means of snap-on fixing on 35 mm mounting rails, in accordance
with DIN EN 60 715.
The electrical connection is established using screw terminals.
The connection to the bus is established using the bus connection terminal
supplied.
The device is ready for operation once the mains voltage of
U = 115...230 V AC and the bus voltage have been applied.
s
Accessibility to the device for the purpose of operation, testing,
visual inspection, maintenance and repair must be provided
(conform to DIN VDE 0100-520).
Note:
Requirements for commissioning
In order to commission Analogue Input AE/S 4.2, a PC with ETS2 version
V1.3 or higher is required as well as an interface to the bus, e.g. via an
RS232 interface or via a USB interface. The device is ready for operation
when the mains voltage of 230 V AC and the bus voltage have been applied.
Installation and commissioning may only be carried out by skilled
electricians. When planning and installing electrical installations, the relevant
norms, guidelines, regulations and specifications must be observed.
– Protect the device from damp, dirt and damage during transport, storage
and operation.
– Only operate the device within the specified technical data!
– Only operate the device in the enclosed housing (distribution board)!

Analogue Input AE/S 4.2 may not be mounted outdoors.
In order to optimise the measuring or monitoring values,
the technical data of the sensor manufacturers must be
observed. The same applies to the specifications of the
sensor manufacturers as regards equipment for lightning
protection.
