5.1 Maintenance
We recommend that you use the following checklist to check the condition of the
3500 Galvanic Isolator Interface system installation at least once every two
years. Use this list more frequently if the installation is in a particularly harsh
environment.
"
Modules are labeled properly and in the correct position according to the
relevant documentation.
"
Modules and hazardous-area connectors are correctly and legibly tagged, the
connectors are plugged into the matching modules, and the tag details given
comply with the relevant documentation.
"
Modules and hazardous-area connectors are securely plugged into their
matching sockets.
"
All connections to the backplane and to the hazardous-area connectors are
properly made.
"
Inspect connecting cables to backplanes and to hazardous-area connectors
for the following:
•
Specified type and rating
•
Correctly routed and segregated (particularly in the Bently Nevada
enclosures). Non-Intrinsically Safe and Intrinsically Safe wiring MUST be
separated by 50 mm minimum. Reference local wiring codes.
•
Not frayed or otherwise damaged.
•
Cable shields and transducers (when applicable) are properly earthed.
•
One backplane power LED is on for each installed power supply.
•
The power LEDs on all modules are on.
