[DESIGN PRECAUTIONS] DANGER Do not use the GOT as the warning device that may cause a serious accident. An independent and redundant hardware or mechanical interlock is required to configure the device that displays and outputs serious warning. Failure to observe this instruction may result in an accident due to incorrect output or malfunction.

[MOUNTING PRECAUTIONS] CAUTION The GOT should be used in the environment given in the general specifications of this user's manual. Not doing so can cause an electric shock, fire, malfunction or product damage or deterioration. When mounting the GOT main unit to an enclosure, tighten the mounting screws in the specified torque range.
Page 5
[WIRING PRECAUTIONS] CAUTION Please make sure to ground FG terminal, LG terminal, and protective ground terminal of the GOT power supply unit by applying Class D Grounding (Class 3 Grounding Method) or higher which is used exclusively for the GOT. Not doing so may cause an electric shock or malfunction.

Though the data described herein are produced with our best on the basis of the requirement items and standards of the restrictions gathered by Mitsubishi, they do not completely guaranteed that all mechanical unit manufactured according to the data do not always match the above directives.
*2 The GOT is an open type device (device installed to another device) and must be installed in a conductive control panel. The above test items are conducted in the condition where the GOT is installed on the conductive control panel and combined with the Mitsubishi PLC.
1.1.2 Control panel The GOT is an open type device (device installed to another device) and must be installed in a conductive control panel. It not only assure the safety but also has a large effect to shut down the noise generated from GOT, on the control panel.
1.1.3 Noise filter (power supply line filter) The noise filter (power supply line filter) is a device effective to reduce conducted noise. Except some models, installation of a noise filter onto the power supply lines is not necessary. However conducted noise can be reduced if it is installed.
1.2 Requirements for conpliance with the Low Voltage Directive The Low Voltage Directive is mandatory within Europe, effective 1st January 1997. The Low Voltage Directive requires each device which operates with power supply ranging from 50VAC to 1000V and 75VDC to 1500V to satisfy necessary safety items.
1.2.3 Control panel Because the GOT is open type equipment (device designed to be stored within another device), be sure to use it only when installed in a control panel. 1) Shock protection In order to prevent those who are unfamiliar with power facility, e.g., an operator, from getting a shock, make sure to take the following measures on the control panel.
1.2.5 External wiring 1) External devices When a device with a hazardous voltage circuit is externally connected to the PLC, select a model which complies with the Low Voltage Directive’s requirements for isolation between the primary and secondary circuits. 2) Insulation requirements Dielectric withstand voltages are shown in the following table.
