Check Measures Done
EMC characteristics of in-
dividual units / all units
tested once installed?
Test EMC characteristics under operating condi-
tions, e.g. while hand-held radios are in use, or
HF frequency generators are close by. Test static
discharge with operating personnel, test mutual
interference between units under different operat-
ing conditions.
Earthed parts connected
correctly?
The connections between the units, racking bars,
earth conductors and shield bars are important.
Inactive metal parts should be connected over a
wide surface area and earthed at a central point;
with insulated metal: Remove insulation or use
special contact fixings; protect the connection
from corrosion; connect the cabinet doors to the
body of the cabinet using earthing straps.
Cable groups laid sepa-
rately?
Separate cables into groups. Supply and signal
leads should be laid separately.
Are the shields connected
correctly?
Use shielded cables for analogue and data leads;
use metallic plugs; connect cable shields to shield
bar at point of entry to cabinet; connect cable
shields over a wide surface area and with low im-
pedance.
Equipotential bonding car-
ried out?
If the installation extends over a wide area: lay
equipotential bonding cable.
Are inductive loads
switched?
Sufficient fuse protection should be used with in-
ductive loads
24 VDC power supply? Power supplies must conform to EN
60742:9/1995, EN 60950-1:2006/A11:2009 or EN
50178: 10/97.
