3.6 EMC Installation
The chassis must be securely bonded to the local EMC ground. In most installations this will
be the back plate, cabinet walls or other access point to the local equipotential common
bonding network. Connection to the analyser should be made using the shortest possible
length of heavy-gauge braid. The braid should be clamped between the cable clamping
washers provided on the functional earth terminal. This is an M5 stud located to the rear of the
analyser, see Figure 1.1.
Interconnecting cables used for all input, analogue output and serial output should be
screened, or equivalent protection provided, as described in Sections 3.2 and 3.3.
All cables should be routed along a low resistance parallel earth conductor to divert earth
currents and allow the screened cables to be grounded at both ends.
The whole EMC ground bonding network should follow best practice so that the back plate,
cabinet walls, parallel earth conductors and other structural elements of the installation form an
equipotential common bonding network. The network should be connected as directly as
possible preferably using metal-to-metal bonding at multiple points. Bonds should make good
reliable low-resistance connections.
