4. Loading and Installation
Precautions when handling the A1S64TC and installation enviroment
are explained.
For details of implementing and setting up this unit, please refer to the
User's Manual for the PC CPU used.
4.1
Handling Instructions
1) The module case is made of plastic. Be sure not to drop it or
subject it to strong vibration.
2) Do not remove the module printed circuit boards from the case.
It may cause trouble.
3) When connecting the wiring, do not allow wire cuttings or other
foreign matter to enter from the top of the module. Remove any
foreign matter from the module.
4) Tighten the module installation screws within the following
tightening torque range.

*: Use only for A1S64TCTTBW-S1.
4.2 Installations Enviroment
Never install the AnS series PC in the following environments:
1) Locations where the ambient temperature is outside the range of 0
to 55 .
2) Locations where the ambient humidity is outside the range of 10 to
CH3
90%RH.
3) Locations where dew condensation takes place due to sudden
temperature changes.
CH4
4) Locations where there are corrosive and/or combustible gasses.
5) Locations where there is a high level of conductive power (such as
dust and iron filings, oil mist, salt, and organic solvents).
6) Locations exposed to the direct rays of the sun.
7) Locations where strong power and magnetic fields are generated.
8) Locations where vibration and shock are directly transmitted to the
main module.
5. Wiring
The precaution when wiring and the module connection example are
shown below.
5.1 Precaution when wiring
In order to have the best result from the A1S64TC functions and to
make the system highly reliable, an external cabling with low noise
effects are necessary.
The external wiring precautions are shown below:
1) Use separate cables for the alternating current and A1S64TC
external input signals to avoid A/C surges and induction effects.
2) Do not bunch the cables with the main circuit, high-voltage cable or
load cables from other than PC, or install them close to each other.
Install the cables far apart from high-frequency circuits, such as the
high-voltage cable and inverter load main circuit, as much as
possible.
This increases the noises, surges, and induction.
3) Perform a one-point grounding for the shielded line and shields of
the seal and cable at the PC. However, there may be cases when
grounding should be performed externally depending on the noise
condition.
