NOTE: The terminals of the board are protected with a rubber pin. Be sure to leave the pin in the
unused terminals in order to avoid disturbances.
Connections between AC drives with OPTD1
Basic connection:
Connect the output 1 of Device 1 to the input 2 of Device 2 and the input of Device 1 to the output 2
of Device 2. Note that in the end devices one terminal pair remains unused. See Figure 24 below.
