5. Mounting intervals
When replacing the GOT800, A77GOT, or A64GOT series with the GOT1000 series, some models and
connection types require larger mounting intervals than the GOT800, A77GOT, and A64GOT series. The
following describes the precautions.
For intervals required for each product, please refer to the product installation interval section in the GOT1000
catalog.
In addition, when installing a communication unit or option unit on the GOT to use the multi-channel function,
refer to GT15 User’s Manual for the E dimension.
5.1 GOT800 and A77GOT series
Among the mounting intervals (A to F dimensions in the above figure), the F dimension for the GOT1000 series
is larger than the F dimension for the A851GOT with the bus connection or the A852GOT with the CC-Link
connection. The following table shows the dimension.
When using the multi-channel function, consider the thickness of the communication unit to be mounted.
For details, refer to the chapter regarding the multi-channel function in the GOT1000 Series Connection
Manual.
