6. Handling precaution
1) Do not drop or give impact on the product.
2) Do not detach PCB from the case, it may cause malfunction.
3) During wiring or other work, do not allow any wire chips get inside the product.
4) Switch off the external power before mounting or removing the module and
the cable.
5) Ensure to turn off the drive device for detaching or inserting the cable
7. Wiring
1) Ensure to separate the power line and the signal line during wiring.
2) Wire the cable as short as possible.
3) Use the separate cable between the AC power line and the signal line not to be
affected by the AC surge or inductive noise.
4) Use the stable external power source for DC24V.
5) Place the cable away from heat and avoid direct contact with oil for long. It may
cause malfunction, short or damage.
