1. Trouble-free operation and reliability of the device can only be guaranteed if the device is not subjected to any other
climatic conditions than those stated under "Specification".
2. Prior to opening it, disconnect device and supply voltage source. Make sure that all parts of the device are protected
against direct touching when mounting the device and setting its connections.
3. Please always adhere to the standard safety regulations for electric devices, power systems and light-current
installations, and make sure that your national safety regulations (e.g. VDE 0100) are observed.
4. If device is to be connected to other devices (e.g. PC) the circuitry has to be designed most carefully. Internal connection
in third party devices may result in not-permissible voltages.
5. If there is a risk whatsoever involved in running it, the device has to be switched off immediately and to be marked
accordingly to avoid re-starting.
Operator safety may be at risk if:
- there is visible damage to the device
- the device is not working as specified
- the device has been stored under unsuitable conditions for a longer time.
In case of doubt, please return device to manufacturer for repair or maintenance.
Installation and commissioning:
Connect the EASY BUS-transmitter to interface converter according to the wiring diagram via a 2-pin connection
cable (twisted line recommended).
Check, if a operational 9V battery is connected.
Then connect the interface converter to the RS232-interface of your personal computer.
Unless the interface converter EBW2 is properly handled it may be damaged. This may also result in the
damage of other devices connected.
In such cases we cannot assume any warranty !
GREISINGER electronic GmbH will not assume any warranty for damages to other devices resulting from the
use of the EBW2.
