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.
The terminal numbers and the appropriate wire sizes are shown in Table 2.7.
* 1. Terminals BB and BB1 are only available in the Inverter version with Safety.
* 2. Use shielded twisted-pair cables to input an external frequency reference.
* 3. We recommend using straight solderless terminal on signal lines to simplify wiring and improve reliability.
îš„ Straight Solderless Terminals for Signal Lines
Models and sizes of straight solderless terminal are shown in the following table.
