c) Check that modules and hazardous-area connectors are securely plugged into their
matching sockets.
d) Check that all connections to the backplane and to the hazardous-area connectors are
properly made.
e) Check that connecting cables to backplanes and to hazardous-area connectors are
of the specified type and rating, are correctly routed and segregated (particularly in
Eaton enclosures), and are not frayed or otherwise damaged.
f) Check that cable screens are properly earthed.
Note: It is strongly recommended that only the tests (described in Section 8) and routine
maintenance (described here) should be undertaken by users. If a module is faulty, DO
NOT attempt to make repairs or modifications as these may affect the intrinsic safety of the
module. All faulty units should be returned to the Eaton’s MTL product line or representative
from which they were purchased, for repair or replacement.
Any faulty backplanes supplied by us should also be similarly returned.
