Connect the inverters parallel to each other as shown below and, only on the terminal Inverter, turn ON
the terminating resistor selector switch.
Even if you have only one inverter connected, turn ON the terminating resistor selector switch.
Selecting a terminating resistor appropriate to the cable impedance improves the terminating effect.
For this inverter, however, turning ON the terminating resistor selector switch enables the built-in termi-
nating resistor (120 ).
*1. If the communications are unstable, install a terminating resistor appropriate to the impedance of the cable to
each cable end. The resistance of the terminating resistor built into this inverter is 120 .
