2.4 Safety guidelines
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.
Requirements of Directive 2014/34/EU (ATEX) and IECex must be observed
The respective national regulations for Ex use must also be complied with (e.g. EN 60079-10
and EN 60079-14).
2.
Install the displaying device according to the manufacturer's specifications and the valid
standards and regulations.
3.
The device may be connected to approved intrinsically safe circuits with his maximum values.
4.
For units with optional output switch, the output switch and the switching device must be supplied
from the same intrinsically sage circui
t as the GIA …!
Only approved intrinsically safe switching devices may be used which correspond to the specified
maximum values of the circuit. The total capacitance and inductance of the devices GIA … (incl.
switching output) and the switching devices, including the connection cable values, may not
exceed the allowable for the intrinsically safe circuit totals. If concentrated inductances and
capacitances exist, the manufacturer must be consulted for permission.
5.
Modifications or repairs of the device may not be performed by the customer.
For maintenance or repair the device must be sent to the manufacturer.
6.
The opening of the devices is only permitted outside the hazardous area.
7.
To configure GIA ... VO-ex and GIA ... WK-ex the cover has to be carefully removed to get
access to the needed buttons. Exposed parts must not be damaged!
This has to be done only by trained personnel and with consideration of adequate ESD safety
precautions.
Take care to insert the sealing correctly when reassemble the cover.
8.
The devices GIA ... VO(T) - ex meet the requirements of intrinsic safety only after angel plugs,
which are appropriate to the required IP protection degree, are connected. The devices shall be
installed in places that are protected against external damage.
9.
The devices back side (GIA ... VO(T) -
ex and GIA … WK - ex) may not be cleaned with a cloth or
other means, which can generate an electrostatic charge.
10.
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”.
11.
When connecting the device to other devices (e.g. PC) the interconnection has to be designed
most thoroughly as internal connections in third-party devices (e.g. connection GND with
protective earth) may lead to undesired voltage potentials.
12.
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.
13.
Do not use these products 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.
