CH1 to CH4 CH5 to CH8
To the earth terminal on
the MX100, MW100, or
equivalent device
Pins 13 on each output connector are not connected internally, therefore you can choose
whether or not to make the connections shown in the wiring diagram.
In order to ensure continuity from the MX100, MW100, or equivalent’s earth to the heat
sink of the module under test, you must fasten the module with screws after installing it
onto the MX150 base plate.
Terminals Measured Criteria
Output terminal to earth terminal on the MX100,
MW100, or equivalent 20 MΩ or more at DC 500 V
