7.1.2 Control Panel
The PLC is an open type device (device installed to another device) and must be installed in a control panel. This is
needed to prevent electric shock by touching XGB PLC and reduce the PLC-generated noise. Install the XGB PLC
in a metallic panel to reduce PLC-generated EMI (Electro-magnetic interference),
The specifications for the control panel are as follows:
(1) Control panel
The PLC control panel must have the following features:
(a) Use SPCC (Cold Rolled Mild Steel) for the control panel.
(b) The steel plate should be thicker than 1.6mm.
(c) Use isolating transformers to protect the power supply from external surge voltage.
(d) The control panel must have a structure which the radio waves does not leak out.
For example, make the door as a box-structure so that the panel body and the door are overlapped each other. This
structure reduces the surge voltage generate by PLC.
(e) To ensure good electrical contact with the control panel or base plate, mask painting and weld so that good
surface contact can be made between the panel and plate.
