• The entire surface of the NS-series PT must be covered with electromag-
netic shielding (specified below) that is also grounded using conductive tape
(e.g., copper tape).
• Gaps in the door of the control panel must be completely filled or covered
with gaskets or other material.
• Gaps between the PT and the panel cutout must be completely covered with
conductive tape, such as copper tape, and the PT must be secured using
