Safety instructions:

This device has been designed and tested in accordance with 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 the device.

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". If the device is transported from a cold to a warm
environment condensation may cause 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.

2. General instructions and safety regulations for electric, light and heavy current plants, including domestic safety
regulations (e.g. VDE), have to be observed.

3. If device is to be connected to other devices (e.g. via PC) the circuitry has to be designed most carefully. 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. 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 a 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.

5. Warning:
Do not use this product as safety or emergency stop devices, or in any other application where failure of the product
could result in personal injury or material damage.

Failure to comply with these instructions could result in death or serious injury and material damage.

Disposal instructions:

The device must not be disposed in the regular domestic waste.
Send the device directly to us (sufficiently stamped), if it should be disposed. We will dispose the device appropriate and
environmentally sound.
