Precautions for Correct Use
• Use the NX1W-CIF11 (non-isolated type) only when there is no difference in electrical poten-
tial between device grounding points. Do not allow the communications distance to exceed
50 m. Connect the shield on the communications cable at both ends to the SHLD or FG ter-
minals on the RS-422A/485 terminal blocks to ground it.
• Use the NX1W-CIF12 (isolated type) if there is a difference in electrical potential between de-
vice grounding points or for long distance communications (500 m max.). Connect the shield
on the communications cable only at the Option Board to ground it. If the shield is connected
at both ends of the cable when there is a difference in electrical potential, the devices may be
damaged.
