Servo amplifiers with a capacity below 1.5kW will have connector-type terminal
blocks for main circuit terminals. Follow the procedure below when connecting to
the terminal block.
Connection Procedure
• Strip the end of the wire, leaving the ends twisted together.
• Open the wire insert opening of the terminal block (plug) with a tool using either
of the two procedures shown in Fig. A and Fig. B on the following page.
1. Fig. A: Use the provided lever to open the wire insert opening .
Fig. B: Using a commercially available 1/8in (3.0 to 3.5mm) slotted
screwdriver, press down firmly on the screwdriver insert
opening to release the wire insert slot.
2. Figs A and B : Insert the wire end into the opening and then clamp it
tightly by releasing either the lever or the screwdriver.
• Remove the terminal block from the servo amplifier prior to wiring.
• Insert only one wire per terminal on the terminal block.
• Make sure that the core wire is not electrically shorted to adjacent core wires.
• Reconnect any wires that were accidentally pulled out.
