ZENITH-P
5.6 INSTRUMENTS
• All measuring instruments have ATEX / IECEx separate certificates. Installation and maintenance shall be done as prescribed
by manufacturer documents.
• Only SCAME approved instruments can be mounted.
If the junction boxes are NOT fitted with wiring by SCAME, each Zenith-P Enclosure shall be subject to a
routine dielectric streght test of 1000 V + 2U rms or 1500 V rms, whichever is the greater applied between the
terminal block and the enclosure for a period of 60 s as required by clause 6.1 of IEC / EN 60079-7. Alternatively, a
test shall be carried out at 1.2 times the test voltage, but maintained for at least 100 ms.

6. SERVICING AND MAINTENANCE AND REPAIRING

Inspection and maintenance of this equipment shall be carried out by suitably trained personnel in accordance
with the applicable code of practice (e.g. IEC / EN 60079-17). During servicing, it is particularly important to
check those components upon which the type of protection depends.

6.1 ROUTINE MAINTENANCE

Routine maintenance is required in order to guarantee the efficiency of the enclosure and to maintain the required level of
protection.
1) Check that the lid seal is in place and not damaged
2) Check that all the lid fixing screws are in place and secured
3) Check that the mounting screws/bolts are tight and free of corrosion
4) Check the security of all cable glands
5) Check the enclosure for damage
6) In zones with presence of combustible dusts, it is necessary to periodically clean the upper surface of the box, limiting the
depth of the layer to less than 5 mm.
