4.1.1 Notes on handling the module

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 modules case, memory card, terminal
block cover, or pin connector.
(2) Do not remove the module printed wiring board from the case. Otherwise, a
malfunction may occur.
(3) Use caution to prevent foreign matter, such as wire chips, falling into the
module during wiring. If foreign matter enters the module, remove it.
(4) Use the fallowing torque range to tighten the module fixing screws and
terminal block screws:
Module fixing screw (M4 screw)
I/O module (M3.5 screw)
Power supply module terminal screws (M3.5 screw)
(5) Observe the following points when you are installing the DIN rail:
(a) Applicable DIN rail type (JIS C 2812)
TH35-7.5Fe
TH35-7.5Al
TH35-15Fe
(b) DIN rail installation screw interval
When you are using the TH35-7.5Fe or TH35-7.5Al DIN rail, tighten
the DIN rail installation screw with a pitch of 200 mm (7.87 inch) or
less to maintain the strength.
35 mm
(1.38 inch)
(6) When installing the base unit to DIN rail in an environment with large
vibration, use a vibration-proofing bracket (A1S-PLT-D). Mounting the
vibration-proofing bracket (A1S-PLT-D) enhances the resistance to vibration.
Depending on the environment to set up the base unit, it is also
recommended to fix the base unit to the control panel directly.
