10 Safety Advice
This chapter is a summary of the key safety measures. The summary
is supplementary to existing rules which staff also have to study.
The safety of persons and equipment in hazardous areas depends on
compliance with all relevant safety regulations. Thus, the installation
and maintenance staff carry a particular responsibility, requiring
precise knowledge of the applicable regulations and conditions.
The notes listed below in section 10.1 must be heeded to avoid injury
and damage to equipment !
10.1 Installation and operation
Please note the following when installing and operating the device:
The in each case valid national regulations for installation and assembly apply (e.g. IEC/EN
60079-14).
The HMI device has been certified as a fixed installed device. It must be fixed with a bracket
or be secured in another way at a specified position.
The HMI device must be disconnected from the mains for a change of position. The EPL
must be adhered to.
The HMI device must only be switched on when it is closed.
The HMI devices may be installed in zones 1, 2, 21 or 22.
For use according to NEC, please refer to drawings 201717540 and 201133510. Any pre-
installations made ex-factory may have to be complemented accordingly.
The intrinsically safe circuits must be installed according to applicable regulations.
When installed in zones 1, 2, 21 and 22, intrinsically safe devices suitable for
categories 2G, 3G, 2D and 3D may be connected to the intrinsically safe power supply
circuits.
If the HMI devices are installed in areas exposed to the risk of dust explosions, the maximum
values of Group IIB apply to the intrinsically safe circuits.
Interconnecting several active devices in an intrinsically safe circuit may result in different
safe maximum values. This could compromise intrinsic safety !
The safe maximum values of the connected field device(s) must correspond to the values
listed on the data sheet or the EC type examination certificate.
During assembly and operation of the HMI device electrostatic surface charging must not
exceed that caused by manual rubbing.
