Control cabinet
2
The GOT is an open type device (device installed to another device) and must be installed in a conductive
control panel or cabinet.
It not only assure the safety but also has a large effect to shut down the noise generated from GOT, on the
control panel.
(1) Control cabinet
(a) Use a conductive control cabinet.
(b) When attaching the control cabinet's top plate or base plate, mask painting and weld so that
good surface contact can be made between the cabinet and plate.
(c) To ensure good electrical contact with the control cabinet, mask the paint on the installation
bolts of the inner plate in the control cabinet so that contact between surfaces can be ensured
over the widest possible area.
(d) Earth the control cabinet with a thick wire so that a low impedance connection to ground can
be ensured even at high frequencies. (22mm 2 wire or thicker is recommended.)
(e) Holes made in the control cabinet must be 10 cm (3.94inch) diameter or less. If the holes are
10cm (3.94inch) or larger, radio frequency noise may be emitted.
In addition, because radio waves leak through a clearance between the control panel door and
the main unit, reduce the clearance as much as practicable. The leakage of radio waves can
be suppressed by the direct application of an EMI gasket on the paint surface.
