Basic Safety Instructions - Siemens SITRANS P500 Instrucciones De Operación

WARNING
Loss of safety of device with type of protection "Intrinsic safety Ex i"
If the device has already been operated in non-intrinsically safe circuits or the electrical specifications have not been
observed, the safety of the device is no longer ensured for use in hazardous areas. There is a danger of explosion.
Connect the device with type of protection "Intrinsic safety" solely to an intrinsically safe circuit.
•
Observe the specifications for the electrical data on the certificate and in Chapter "Technical data (Page 27)".
•
WARNING
Use of incorrect device parts in potentially explosive environments
Devices and their associated device parts are either approved for different types of protection or they do not have
explosion protection. There is a danger of explosion if device parts (such as covers) are used for devices with explosion
protection that are not expressly suited for this type of protection. If you do not adhere to these guidelines, the test
certificates and the manufacturer warranty will become null and void.
Use only device parts that have been approved for the respective type of protection in the potentially explosive
•
environment. Covers that are not suited for the "explosion-proof" type of protection are identified as such by a notice
label attached to the inside of the cover with "Not Ex d Not SIL".
Do not swap device parts unless the manufacturer specifically ensures compatibility of these parts.
•
WARNING
Risk of explosion due to electrostatic charge
To prevent the build-up of an electrostatic charge in a hazardous area, the key cover must be closed during operation and
the screws tightened.
The key cover may be opened temporarily at any time for the purposes of operating the pressure transmitter, even during
plant operation; the screws should then be tightened again.
NOTICE
Electrostatic-sensitive devices
The device contains electrostatic-sensitive devices (ESD). ESD can be destroyed by voltages far too low to be detected by
humans. These voltages can occur if you simply touch a component part or the electrical connections of a module without
being electrostatically discharged. The damage to a module caused by overvoltage cannot normally be detected
immediately; it only becomes apparent after a longer period of operating time has elapsed.
Protective measures against the discharge of static electricity:
Make sure that no power is applied.
•
Before working with modules, make sure that you discharge static from your body, for example by touching a grounded
•
object.
Devices and tools used must be free of static charge.
•
Hold modules only by their edges.
•
Do not touch connector pins or conductor tracks on a module with the ESD notice.

Basic safety instructions

WARNING
Wetted parts unsuitable for the process media
Danger of injury or damage to device.
Hot, toxic and corrosive media could be released if the process medium is unsuitable for the wetted parts.
Ensure that the material of the device parts wetted by the process medium is suitable for the medium. Refer to the
•
information in "Technical data" (Page 27).
