Shield Box
A shield box, which is a closed metallic enclosure, is effective as reinforced shielding
against electromagnetic interference (EMI) from SERVOPACKs. The structure of the
box should allow the main body, door, and cooling unit to be attached to the ground.
The box opening should be as small as possible.

Do not connect the digital operator and the analog monitor cable to the SERVOPACK
during operations. Connect them only when the machinery is stopped during mainte-
nance.
