5.1.2 Wiring Main Circuit Terminal Block (Spring Type)
The terminals for the main circuit power supply and control power supply terminals of SERVOPACKs with a
capacity below 1.0 kW are detachable. Connect the terminals to the power supply connectors in the following
manner.
(1) Wire Size
Wire can be used simply by stripping back the outer coating. The following are applicable wire sizes.
• Single wire: φ0.5 (0.02) to φ1.6 (0.06) mm (inches)
• Braided wire: AWG28 to AWG12
(2) Connection Procedure
1. Strip the end of the wire.
2. Open the wire terminal on the terminal block housing (plug) with the tool using the procedure shown in
Fig. A or B.
• Insert the hook of the lever into the top hole, which provided with the SERVOPACK and press down
to open the wire terminal as shown in Fig. A.
• Use a standard flat-blade screwdriver (blade width of 3.0 to 3.5 mm (0.12 to 0.14 in)). Put the blade
into the slot, as shown in Fig. B, and press down firmly to open the wire terminal.
Either the procedure shown in Fig. A or B can be used to open the wire insert opening.
3. Insert the wire core into the opening and then close the opening by releasing the lever or removing the
screwdriver.
• Observe the following precautions when wiring main circuit terminal block.
• Remove the terminal block from the SERVOPACK 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.
