Example of Cable Clamp
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.
Note: 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 maintenance.
