4.PC Connection
4.1 Things to Know before connection
Warning
The connected or built-in peripherals with opposite polarities are not allowed.
Warning
The device only operates when connecting with grounded power. No operation is
allowed when the device power is ungrounded or only impedance is grounded.
Warning
Rated voltage of the device in use shall be in accord with power feature of the product.
Note
Only the peripheral devices approved for industrial application can be used. When
operating the PC, hot swappable IO modules (USB) can be used. The IO devices without
hot swap function can only be connected when the PC is powered off.
4.2 Product Grounding
Low impedance ground connection is more helpful to release the interference produced by
the external cables, the signal cables or the cables connecting the IO module to the
grounding system.
Ground Terminals
The ground terminal (large
①
surface and large area contact) shall
be connected with the cabinet
installed with the PC or the central
grounding busbar on the device.
The minimum cross section area of
the cable shall be no less than
2.5mm2, and the grounding
resistance shall be no more than
0.1
Ω
