[Installation Precautions]
CAUTION
● Use the programmable controller in an environment that meets the general specifications in the Safety
Guidelines (IB-0800525). Failure to do so may result in electric shock, fire, malfunction, or damage to
or deterioration of the product.
● To mount a module, place the concave part(s) located at the bottom onto the guide(s) of the base unit,
and push in the module, until the hook(s) located at the top snaps into place. Incorrect interconnection
may cause malfunction, failure, or drop of the module.
● To mount a module with no module fixing hook, place the concave part(s) located at the bottom onto
the guide(s) of the base unit, push in the module, and fix it with screw(s). Incorrect interconnection
may cause malfunction, failure, or drop of the module.
● Tighten the 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. For the specified torque range, refer to the MELSEC iQ-
R Module Configuration Manual.
● 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.
● Beware that the module could be very hot while power is on and immediately after power-off.
● 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 before powering
on the system for operation. Also, attach an extension connector protective cover
extension cable connector as necessary. Directly touching any conductive parts of the connectors
while power is on may result in electric shock.
