Safety instructions and measures
1.1 Notes on possible severe personal injury
DANGER !
Risk of fatal injury due to electric shock (230 V version).
Î
Before connecting wiring, performing any work on the device or opening the device,
disconnect the voltage supply and protect it against unintentional reconnection.
Î
Only use power interruption devices that are protected against unintentional recon-
nection of the power supply.
Risk of fatal injury due to the ignition of an explosive atmosphere.
Incorrect installation, operation or maintenance of the differential pressure meter in
potentially explosive atmospheres may lead to ignition of the atmosphere and ultimately
to death, even with a harmless supply voltage.
Î
For mounting and electrical installation in hazardous areas, observe the explosion
protection approvals as well as the relevant electrotechnical regulations and the
accident prevention regulations that apply in the country of use. EN 60079-14
applies in Europe.
Î
Do not connect the electrical supply before mounting is completed and any unused
cable entries have been sealed.
Î
Installation, operation or maintenance of the differential pressure meter must only be
performed by personnel with qualifications according to Clause 4.5 of IEC 60079-
14 who has undergone special training or instructions or who is authorized to work
on explosion-protected devices in hazardous areas.
Risk of fatal injury as a result of electrostatic discharge at the housing.
The housing of the differential pressure meter is made of polycarbonate and may be-
come electrostatically charged when handled incorrectly. An electric spark generated by
electrostatic discharge may lead to ignition of a potentially explosive atmosphere and
cause death.
Î
Ensure that the device, cables and other plant components cannot rub against each
other.
Î
Do not rub dry the housing surface of the differential pressure meter.
Î
Only use a damp cloth or wipes (e.g. with diluted mild soap or detergent) to clean
the housing surface.
