Isolate the PLC power, I/O devices and power devices as follows.
(4) If using DC24V of the power module
(a) Do not connect DC24V of several power modules in parallel. It may cause the destruction of a module.
(b) If a power module can not meet the DC24V output capacity, supply DC24V externally as presented
below.
(5)
AC110V/AC220V/DC24V cables should be compactly twisted and connected in the shortest distance.
(6) AC110V/AC220V cable should be as thick as possible(2mm
2
) to reduce voltage drop.
(7) AC110V/ DC24V cables should not be installed close to main circuit cable(high voltage/high current) and
I/O signal cable. They should be 100mm away from such cables
