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) Tighten screws (such as a module fixingscrew) within the tightening
torque range specified in the table below.
(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.
