Claim 10:
11. A motor-drive system, comprising:
a power converter configured to generate a direct current (DC) voltage based on three voltages received from three supply voltage lines via a voltage source
a metal-oxide varistor (MOV) assembly comprising three metal-oxide varistors (MOVs) configured to respectively couple to the three supply voltage lines, wherein the MOV assembly is configured to couple between the voltage source and the power converter;
an electromagnetic compatibility (EMC) capacitor assembly coupled between the voltage source and the power converter;
a plurality of permanent jumpers configured to respectively couple each of the three MOVs to a system ground;
a housing configured to enclose each of the plurality of permanent jumpers and render each of the plurality of permanent jumpers inaccessible from outside the housing; and
a removable jumper configured to couple the EMC capacitor assembly to the system ground, wherein the removable jumper is exposed outside the housing.
