Cautions on Installation of PI/O Module
INSTRUCTION:
Install the I/O signal line away from the power supply lines or devices that generate
electromagnetic fields. Otherwise malfunctions or failures may occur due to noises, etc.
Do not drop, bump against something, or give strong shocks to the modules. Otherwise
failures may occur.
When wiring the serial PI/O system, be careful with the following.
•
The PI/O modules are not dust-proof. Try to use a dust-proof cabinet if possible.
•
Don’t install it on top of any device which emits much heat (heater, transformer, or register
with high resistance).
•
Don’t install it in the same board as a high-voltage device.
•
Isolate it from a high-voltage line or power supply line.
