5.2 Electrical mounting
Requirements for voltage supply
→ For power supply see product label
Power the instrument via a certified intrinsically safe circuit.
■
For applications that require EPL Gb or Db, the power supply and signal circuit should have a protection level of "ib".
■
Then the interconnections and thus the submersible pressure transmitter will have a protection level of II 2G Ex ib
IIC T4/T5/T6 Gb or II 2D Ex ib IIIC T4/T5/T6 Db, although the submersible pressure transmitter is marked otherwise
(see EN 60079-14 section 5.4).
Note the safety-related maximum values in chapter 3.3 "Special conditions for safe use".
■
Requirements for electrical connection
Fine-stranded leads with bare ends must be finished with end splices.
■
Make sure that no moisture enters at the cable end.
■
Requirements for shielding and grounding
The cable shield is connected conductively with the case.
■
Ground the cable shield at least at one end of the cable, if the lines are longer than 30 m or leave the building.
■
Ground the cable shield at one end, preferably in the non-Ex area (EN 60079-14). The simultaneous connection of
■
the case and the cable shield to ground is only permitted if any accidental energisation between the shield connec-
tion (e.g. at the isolated barrier) and the case can be excluded (see EN 60079-14).
Installation and mounting to zone 0 and zone 20
