Handling precautions
This section explains some notes on handling the CPU module, I/O module, special
function module, power supply module, and base unit.
(1) Do not drop or allow any impact to the module case, memory card, terminal block
connector, or pin connector.
(2) Do not remove the printed-circuit board from the module case.
Doing so may cause failure.
(3) Use caution to prevent foreign matter, such as wire chips, from entering the module
during wiring.
If any foreign matter has entered the module, remove it.
(4) When using the extension base unit (QA1S6 B), be sure to install the power supply
module.
Although modules with light load may operate without the power supply module,
stable operation is not guaranteed.
(5) Tighten screws (such as a module fixing screw) within the tightening torque range
specified in the table below.
(6) When using extension cables, do not install them together with the main circuit
cables (high voltage, large current), or bring them close to each other.
