For฀immunity฀reasons,฀the฀signal฀lines฀for฀the฀digital฀inputs,฀outputs฀and฀
encoder฀must฀be฀shielded:

All฀shielded฀cables฀are฀to฀be฀attached฀at฀both฀ends฀to฀the฀shield฀ter-
minals฀provided฀or฀should฀be฀connected฀to฀the฀connector฀housing.

Use฀cables฀with฀a฀braided฀shield,฀with฀a฀minimum฀coverage฀of฀80฀%.

Any฀interruptions฀to฀the฀shielding฀e.g.฀at฀terminals,฀should฀be฀bridged฀
at฀low฀impedance฀over฀a฀wide฀area.

All฀connectors฀or฀sockets฀should฀be฀fastened฀with฀screws฀to฀ensure฀
ample,฀conductive฀contact฀between฀the฀braided฀shield฀and฀the฀front฀
plate.
The฀shield฀for฀the฀encoder's฀signal฀lines฀is฀connected฀to฀the฀connector฀
housings.
The฀shields฀for฀the฀digital฀inputs฀and฀outputs฀should฀be฀connected฀to฀the฀
front฀of฀the฀servo฀amplifier,฀as฀shown฀in฀the฀diagram฀below.

Remove฀the฀outer฀cable฀sheath฀and฀
the฀braided฀shield฀to฀the฀required฀wire฀
length.฀Secure฀the฀wires฀with฀a฀cable฀
tie.฀
Remove฀the฀outer฀cable฀sheath฀to฀a฀
length฀of฀approx.฀30 mm.฀Be฀careful฀
not฀to฀damage฀the฀braided฀shield.฀
Strip฀all฀the฀wires฀and฀fit฀end฀ferrules.
Use฀the฀cable฀ties฀to฀attach฀the฀cable฀
to฀the฀shielding฀plate฀on฀the฀side฀(1)฀or฀
bottom฀(2)฀of฀the฀servo฀amplifier.฀
Press฀the฀cable's฀braided฀shield฀firmly฀
against฀the฀shielding฀plate฀on฀the฀ser-
vo฀amplifier฀using฀a฀cable฀tie.฀
Alternatively฀you฀can฀use฀the฀shielded฀
connection฀terminals฀(3)฀(available฀as฀
an฀accessory).฀These฀hook฀into฀the฀
bottom฀shielding฀plate฀and฀guarantee฀
optimum฀contact฀between฀the฀shield฀
and฀the฀shielding฀plate.
