result in not-permissible voltages impairing or destroying the device or another device
connected.
3. Warning: Operating the device with a defective mains power supply (e.g. short circuit from
mains voltage to output voltage) may result in hazardous voltages at the device (e.g. at sensor
socket)
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
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.
