3 INSTALLATION AND MODULE MOUNTING
Construct an emergency stop circuit and an interlock circuit outside this
product. Unless they are so constructed, failure of this product may result in
machine breakdown or accident.
Keep the input and output currents of any I/O module within the maximum
permitted current values. If an overcurrent is allowed to flow in the I/O
module, the component part(s) involved may be damaged, resulting an
accident, fire, or product failure.
Do not use a transceiver, cellular phone, or the like near any I/O module. Such
communication equipment generates noise, which may result in malfunction or
system failure.
