2.5 — Electromagnetic compatibility (EMC norms)
The equipment's EMC norms depend on the type of installation being carried out (such as
cable termination and grounding) and on the operating conditions (such as equipment,
setting options for the electrical/electronic units, and presence of dummy covers).
Before carrying out any installation, turn-up, tests, and operation and maintenance
operations, carefully read the related sections of this Manual, in particular:
•
Hardware Installation
•
Maintenance and Trouble-clearing
The norms set down to guarantee EMC compatibility are indicated in this manual by the
symbol and term:
EMC General Norms - Installation
•
All connections towards the external source of the equipment made with shielded
cables use only cables and connectors recommended in this manual or in the relevant
Plant Documentation, or those specified in the Customer's "Installation Norms" (or
similar documents).
•
Shielded cables must be properly terminated.
•
Install filters outside the equipment as required.
•
Ground connect the equipment using a conductor with proper diameter and
impedance.
•
Mount shields (if used), previously positioned during the installation phase, but not
before having cleaned and degreased them.
•
Before inserting the shielded unit, clean and degrease all peripheral surfaces (contact
springs and connection points, etc.)
•
Fasten the units to the subrack with screws.
•
To correctly install EMC-compatible equipment, follow the instructions provided.
