4. INSTALLATION AND WIRING

4.1 Module Installation

4.1.1 Instructions for handling

CAUTION

Use the Motion controller in an environment that meets the general specifications contained in this

manual. Using this Motion controller in an environment outside the range of the general specifications

could result in electric shock, fire, operation failure, and damage to or deterioration of the product.

Hold down the module loading lever at the module bottom, and securely install the module fixing hook

into the fixing hole in the base unit. Incorrect loading of the module can cause an operation failure,

failure or drop. When using the Motion controller in the environment of much vibration, tighten the

module with a screw.

Tighten the screw in the specified torque range. Under tightening may cause a drop, short circuit

or operation failure. Over tightening may cause a drop, short circuit or operation failure due to

damage to the screw or module.

Be sure to install the extension cable to connectors of the base unit correctly. After installation, check

them for looseness. Poor connections could cause an input or output failure.

Completely turn off all lines of power supply externally before loading or unloading the module. Not

doing so could result in electric shock or damage to the product.

Do not directly touch the module's conductive parts. Touching the conductive parts could cause an

operation failure or give damage to the module.

This section describes instructions for handling the CPU modules, I/O modules,

intelligent function modules, power supply modules and base units, etc.

(1) Do not drop or apply strong impact on the CPU modules, I/O modules, intelligent

function modules, power supply modules, base units and memory card, etc.

(2) Do not remove modules printed circuit boards from the case in order to avoid

failure.

(3) The module fixing screws and terminal block screws within the tightening torque

range specified below.

Location of screw Tightening torque range

Module fixing screw (M3 12 screw) 0.36 to 0.48

N•m

I/O module terminal block screw (M3 screw) 0.42 to 0.58 N•m

I/O module terminal block fixing screw (M3.5 screw) 0.66 to 0.89

N•m

Power supply module terminal screw (M3.5 screw) 0.66 to 0.89 N•m

(4) Make sure to install the power supply module on the CPU 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 base units are light load type, the

modules may be operated. In this case, because a voltage becomes unstable,

we cannot guarantee the operation.
