Safety Requirements:
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. Mains operation:
• When using a power supply device please note that operating voltage has to be 9 to 12 V DC.
Do not apply overvoltage!! Cheap 12V-power supply devices often have excessive no-load voltage. We, therefore, recommend using regulated voltage power supply devices. Trouble-free operation is guaranteed by our power supply
GNG10.
• Prior to connecting the power supply to the mains make sure that the operating voltage stated at the power supply is
identical to the mains voltage.
2. If device is to be connected to other devices (e.g. via serial interface) 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.
Warning: If device is operated with a defective mains power supply (short circuit from mains voltage to output voltage) this
may result in hazardous voltages at the device (e.g. sensor socket at interface)
3. 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.
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.
