Isolation Bush
In the front of the I/O expansion cabinet (ACB51): for cabinet installation type node and the rear:
for 19-inch rack mount type, the cabinet installation type node is installed in the front. For this
node, the independent grounding plays an important role in the circuit systems.
Therefore, in order that the rear 19-inch rack mount devices do not pass the grounding current
which is important to the node, it and devices manufactured by other companies, must be
insulated with an insulation brush. As devices manufactured by Yokogawa also do not have the
guarantee that it will share a common power supply or grounding with the Model ACB51 itself,
make sure to insulate with an isolation bush.
TIP
The isolation bush of Yokogawa devices can be eliminated if both I/O expansion cabinet types are installing
Yokogawa devices and shares a common power supply and grounding with Model ACB51 and only when other
company devices are insulated with an isolation bush.
