Wiring Control Circuit Terminals
îš‹ Wire Sizes
For remote operation using analog signals, keep the control line length between the Analog Operator or oper-
ation signals and the Inverter to 50 m or less, and separate the lines from main power lines or other control cir-
cuits to reduce induction from peripheral devices.
When setting frequencies from an external frequency source (and not from a Digital Operator), use shielded
twisted-pair wires and ground the shield for the largest area of contact between shield and ground.
Terminal numbers and wire sizes are shown in Table 2.12.
