WARNING
●
Do not touch any terminal while power is on. Doing so will cause electric shock or malfunction.
●
Shut off the external power supply (all phases) used in the system before cleaning the module or
retightening the terminal block screws. Failure to do so may result in electric shock.
CAUTION
● Before performing online operations (especially, program modification of the Motion controller, forced
output, and operation status change) for the running head module from the peripheral device
connected, read relevant manuals carefully and ensure the safety. Improper operation may damage
machines or cause accidents.
●
Do not disassemble or modify the module. Doing so may cause failure, malfunction, injury, or a fire.
●
Use any radio communication device such as a cellular phone or PHS (Personal Handy-phone
System) more than 25cm away in all directions from the programmable controller. Failure to do so
may cause malfunction.
●
Shut off the external power supply (all phases) used in the system before mounting or removing a
module. Failure to do so may cause the module to fail or malfunction.
●
Tighten the terminal block screws within the specified torque range. Undertightening can cause drop
of the component or wire, short circuit, or malfunction. Overtightening can damage the screw and/or
module, resulting in drop, short circuit, or malfunction.
●
After the first use of the product (module and terminal block), do not connect/disconnect the product
more than 50 times (in accordance with IEC 61131-2). Exceeding the limit may cause malfunction.
●
Before handling the module, touch a conducting object such as a grounded metal to discharge the
static electricity from the human body. Failure to do so may cause the module to fail or malfunction.
CAUTION
●
When disposing of this product, treat it as industrial waste.
