4.2.3
Crimp Terminals and Insulating Sleeves
For SGD7S-470A to -780A SERVOPACKs, use crimped terminals and insulating sleeves to
connect the dynamic brake resistor to the terminal block. Do not allow the crimp terminals to
come close to adjacent terminals or the case.
To comply with UL standards, you must use UL-compliant closed-loop crimp terminals and
insulating sleeves for the main circuit terminals. Use the tool recommended by the crimp termi-
nal manufacturer to attach the crimp terminals.
The following tables give the recommended tightening torques, closed-loop crimp terminals,
and insulating sleeves in sets. Use the set that is suitable for your model and wire size.
If you use a SERVOPACK that supports the dynamic brake hardware option specifications and
connect an external dynamic brake resistor, refer to the following section.
