C80 Series Connection and Setup Manual
5 Installation
This section describes precautions for handling the CPU modules, I/O modules, power supply modules and basic base
unit, etc.
(1) Do not drop or apply strong impact on the modules, terminal block connectors and pin connectors.
(2) Do not remove modules printed circuit boards from the case. If you remove them from the case, it may result in
damage.
(3) The module fixing screws and terminal block screws within the tightening torque range specified below:
Module fixing screw (M3x12)
Terminal block screw (M3)
Terminal block mounting screw (M3.5)
Connector screw (M2.6)
Terminal screw (M4) of a power supply module
Terminal screw (M3.5) of a power supply module
(4) Make sure to install the power supply module on the basic base unit and extension base unit. When the power supply
module is not installed and if the I/O modules and intelligent function module installed on the basic base unit are
light load type, the modules may be operated. In this case, because a voltage becomes unstable, we cannot
guarantee the operation.
(5) When an extension cable is used, do not bind the cable together with the main circuit (high voltage, heavy current)
line or lay them close to each other. Keep the cable at least 100 mm away from the line.
