FABRICATION
NOTE ON WIRING
1) Ground both this unit
and external equipment.
2) Fabricate braided shield of external equipment as follows:
- IEC 61162-1 input, AD-10 input (photo coupler): Connect to FG(frame ground).
- IEC 61162-2 input (RS-422/485): Connect to SG(signal ground).
Note: The power section of this equipment is insulated so the potential of SG and FG are the
same. If the shielding is not properly done, the data output IC may be damaged.
