Each electric agitator in the Intelligent Paint Kitchen
system can be remotely controlled by a Variable
Frequency Drive/ Inverter (B) installed in the
non-hazardous location.
Every Variable Frequency Drive/Inverter must be
connected to the Supervisor Module (36) inside a
Supervisor Box (A), and to an agitator in a station.
If your system uses a Variable Frequency
Drive/Inverter to control the agitator, connect a
blue and white/blue twisted wire from the Variable
Frequency Drive/Inverter to the last fiber optic
converter in the wired series.

If a station is connected to multiple Variable
Frequency Drives/Inverters, wire the Variable
Frequency Drives/Inverters together in series,
using terminals 2 and 4 on the Modbus module
installed inside the Variable Frequency Drive/Inverter
as shown. On the final Variable Frequency
Drive/Inverter in the series, install a 120 ohm resistor
to terminate the series.
