For the type CA inverter, the terminal operates as terminal CA. Wiring method Wiring connection Use crimp terminals and stripped wire for the control circuit wiring. For single wire, the stripped wire can be used without crimp terminal. Connect the end of wires (crimp terminal or stranded wire) to the terminal block. 1. Strip the signal wires as follows.
If too much of the wire is stripped, a short circuit may occur with neighboring wires. If not enough of the wire is stripped, wires may become loose and fall out. Twist the stripped end of wires to prevent them from fraying. Do not solder them. Wire strip length 75 2. INSTALLATION AND WIRING 2.6 Control circuit logic erminal PC as a common terminal, and perform wiring as ws. (Do not connect terminal SD on the inverter with the nal of 0 V for the external power supply. When using nals PC and SD as a 24 VDC power supply, do not install ternal power supply in parallel with the inverter.
Doing so cause a malfunction in the inverter due to undesirable nts.)
