1 In General

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.

If the device is transported 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.

If device is to be connected to other devices 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.

Warning:

 If device is operated with a defective mains power supply (e.g. short circuit from mains voltage to output voltage) this may result in

hazardous voltages at the device (e.g. at sensor socket)

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 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.

6.

Warning: 

Do not use these product as safety or emergency stop device, 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.
