[Installation Precautions]
WARNING
● Shut off the external power supply (all phases) used in the system before mounting or removing the
module. Failure to do so may result in electric shock or cause the module to fail or malfunction.
[Installation Precautions]
CAUTION
● Use the programmable controller in an environment that meets general specifications written in Safety
Guidelines included in the base unit. Failure to do so may result in electric shock, fire, malfunction, or
damage to or deterioration of the product.
● To mount this module, place the concave part(s) located at the bottom onto the guide(s) of the base
unit, and push in the module, and make sure to fix the module with screws since this module has no
module fixing hook. Incorrect interconnection may cause malfunction, failure, or drop of the module.
● When using the programmable controller in an environment of frequent vibrations, fix the module with
a screw.
● Before mounting/dismounting the module, be sure to shut off all phases of external power supply used
by the system. Failure to do so may cause product damage.
● Tighten the screws within the specified torque range. Undertightening can cause drop of the screw,
short circuit, or malfunction. Overtightening can damage the screw and/or module, resulting in drop,
short circuit, or malfunction.
● Connectors for wiring must be crimped or pressed with the tool specified by the manufacturer, or must
be correctly soldered. Incomplete connections may cause a short circuit, fire, or malfunction.
● When using an extension cable, connect it to the extension cable connector of the base unit securely.
Check the connection for looseness. Poor contact may cause malfunction.
● When using an SD memory card, fully insert it into the SD memory card slot. Check that it is inserted
completely. Poor contact may cause malfunction.
● Securely insert an extended SRAM cassette or a battery-less option cassette into the cassette
connector of the CPU module. After insertion, close the cassette cover and check that the cassette is
inserted completely. Poor contact may cause malfunction.
● Do not directly touch any conductive parts and electronic components of the module, SD memory
card, extended SRAM cassette, battery-less option cassette, or connector. Doing so can cause
malfunction or failure of the module.
[Wiring Precautions]
WARNING
● Shut off the external power supply (all phases) used in the system before installation and wiring.
Failure to do so may result in electric shock or cause the module to fail or malfunction.
● After installation and wiring, attach a blank cover module (RG60) to each empty slot and an included
extension connector protective cover to the unused extension cable connector before powering on the
system for operation. Failure to do so may result in electric shock.
