1.5 Electromagnetic Compatibility (EMC norms)
The equipment's EMC norms depend on the type of installation being carried out (cable termination,
grounding etc.,) and on the operating conditions (equipment, setting options of the electrical/electronic
units, presence of dummy covers, etc.).
Before carrying out any installation, turn-on, tests & operation and maintenance operations, read carefully
the related sections of this Manual, in particular:
– Hardware Installation
– Maintenance and Upgrade
The norms set down to guarantee EMC compatibility, are distinguished inside this Manual by the symbol
and term:
[1] EMC General Norms - Installation
• All connections (towards the external source of the equipment) made with shielded cables use
only cables and connectors suggested 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 suitably terminated
• Install filters outside the equipment as required
• Ground connect the equipment utilizing a conductor with proper diameter and impedance
• Mount shields (if utilized), previously positioned during the installation phase, but not before
having cleaned and degrease it.
• Before inserting the shielded unit proceed to clean and degrease all peripheral surfaces (con-
tact springs and connection points, etc.)
• Screw fasten the units to the subrack.
• To correctly install EMC compatible equipment follow the instructions given.
[2] EMC General Norms - Turn-on, Tests & Operation
• Preset the electrical units as required to guarantee EMC compatibility
• Check that the equipment is operating with all the shields properly positioned (dummy covers,
ESD connector protections, etc.)
• To properly use EMC compatible equipment observe the information given
[3] EMC General Norms - Maintenance
• Before inserting the shielded unit, which will replace the faulty or modified unit, proceed to clean
and degrease all peripheral surfaces (contact springs and connection points, etc.)
• Clean the dummy covers of the spare units as well.
• Screw fasten the units to the subrack.
