Connecting External Signals
The terminals to which external signals are connected are EXT INPUT and EXT SYNC
INPUT.
Parts to be prepared by the customer
• BNC coaxial cable
EXT INPUT (BNC connector)
These are external signal input terminals for connection to the outputs of external current
sensors or external current shunts. The terminals are provided in the L1, L2, and L3 input
sections. The maximum input voltage is 5V peak. These terminals are enabled when "BNC"
is selected in the "Curr Input Terminal" in the setting menu.
When external current sensors or current shunts are used, it is necessary to set the scaling.
