1.1 Safety
Instructions
This device has been designed and tested in accordance to the safety regulations for electronic devices.
However, its trouble-free operation and reliability cannot be guaranteed unless the standard safety measures and
special safety advises given in this manual will be adhered to when using it.
1. Trouble-free operation and reliability of the device can only be guaranteed if it is not subjected to any other climatic
conditions than those stated under “Specification”.
2. Transporting the device from a cold to a warm environment condensation may result in a failure of the function. In
such a case make sure the device temperature has adjusted to the ambient temperature before trying a new start-up.
3. The circuitry has to be designed most carefully if the device should be connected to other devices. Internal
connection in third party devices (e.g. connection GND and earth) may result in not-permissible voltages impairing
or destroying the device or another device connected.
4. Whenever there may be 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 a risk if:
- there is visible damage to the device or 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.
