Power supply check from extension power supply module
(current consumption calculation)
If the maximum number of CPU modules that can be connected is exceeded and further expansion modules are connected,
add an extension power supply module.
Check if power can be supplied to extension modules with the power supply capacity of the extension power supply module.
Calculate following the procedure below.
1.
Check the power supply capacity of the extension power supply module used.

If the ambient temperature exceeds 40

, use the extension power supply module at the following current
values within the derating range.
2.
Check the current consumption of the extension module.
