14. Zone 1
The device may be installed in Zone 1.
The intrinsically safe output circuits may lead into Zone 1.
15. Dust
The device may be installed in dust groups IIIC, IIIB, and IIIA.
16. Zone 21
The device may be installed in Zone 21.
17. Type of Protection Ex d
For mounting on a housing with type of protection Ex d, at least 5 thread
revolutions must be in mechanical connection with the housing.
18. Type of Protection Ex i
Observe the respective peak values of the field device and the associated
apparatus with regard to explosion protection when connecting intrinsically
safe field devices with intrinsically safe circuits of associated apparatus
(verification of intrinsic safety). Also observe IEC/EN 60079-14 and
IEC/EN 60079-25.
Keep the separation distances between all non-intrinsically safe circuits
and intrinsically safe circuits according to IEC/EN 60079-14.
Intrinsically safe circuits of associated apparatus can be led into
hazardous areas. Observe the compliance of the separation distances to
all non-intrinsically safe circuits according to IEC/EN 60079-14.
Circuits of intrinsically safe apparatus can be led into hazardous areas,
whereby special attention must be paid to maintaining separation
distances to all non-intrinsically safe circuits according to the requirements
in IEC/EN 60079-14.
19. Type of Protection Ex p
When mounting the device in Zone 20, Zone 21 or Zone 22, the inside of
the Ex p housing must not be purged. Remove the dust inside the housing
by cleaning.
20. Housings and Surrounding Enclosures
The housing must not be opened when the device is energized.
Do not install fuse terminals, relays, miniature circuit breakers, contactors
etc. in the enclosure.
Before you close the surrounding enclosure, ensure that the seals are
clean, undamaged, and correctly fitted.
21. Operation, Maintenance, Repair
Prior to using the product make yourself familiar with it. Read the
instruction manual carefully.
Do not remove the nameplate.
Observe the warning markings.
Do not connect or disconnect the electrical connection when energized.
Do not exceed the maximum permitted output current. Prevent short
circuits.
Do not exceed the maximum power dissipation. Refer to nameplate for
maximum power dissipation.
Observe IEC/EN 60079-17 for maintenance and inspection of associated
apparatus.
Observe IEC/EN 60079-17 for maintenance and inspection.
Do not damage the flamepath surfaces between enclosure and enclosure
cover during the opening of the control panel.
If the enclosure is damaged, replace enclosure and enclosure cover.
When energized, only open the housing in the absence of a potentially
explosive atmosphere.
Substitution of components may impair intrinsic safety.
Remove all adhering residues from the device. These residues can be
hazardous to health.
Fill in the form "Declaration of Contamination". You can find this form on
the product detail page at www.pepperl-fuchs.com.
22. Return
Return
If there is a defect, always send back the device to Pepperl+Fuchs.
23. Delivery, Transport, Disposal
Check the packaging and contents for damage.
Check if you have received every item and if the items received are the
ones you ordered.
Store the device in a clean and dry environment. The permitted ambient
conditions must be considered, see datasheet.
