Claim 17:
18. A method, comprising:
placing a metal-oxide varistor (MOV) assembly into a drive enclosure, wherein the MOV assembly comprises three metal-oxide varistors (MOVs) that respectively couple to three supply lines, wherein the MOV assembly couples between a voltage source configured to provide three voltages and a power converter, wherein each of the three supply lines transmits a respective voltage of the three voltages to the power converter;
placing an electromagnetic compatibility (EMC) capacitor assembly into the drive enclosure;
coupling a plurality of permanent jumpers between the MOV assembly and a system ground such that each of the three supply lines respectively couple to the system ground via the three MOVs, wherein each of the plurality of permanent jumpers is enclosed by a housing that renders each of the plurality of permanent jumpers inaccessible from outside the housing; and
coupling a removable jumper between the EMC capacitor assembly and the system ground such that each of the three supply lines respectively couple to the system ground via the EMC capacitor assembly, wherein the removable jumper is exposed outside the housing.
