Appendix B Accessories
B.1 All Brake Resistors & Brake Units Used in AC Motor Drives
Note: Please only use DELTA resistors and recommended values. Other resistors and values will void Delta’s warranty. Please contact your nearest Delta representative for use of special resistors. The brake unit should be at least 10 cm away from AC motor drive to avoid possible interference. Refer to the “Brake unit Module User Manual” for further details.

NOTE
1.Please select the brake unit and/or brake resistor according to the table.
2.If damage to the drive or other equipment is due to the fact that the brake resistors and the braking modules in use are not provided by Delta, the warranty will be void.
3.Take into consideration the safety of the environment when installing the brake resistors.
4.If the minimum resistance value is to be utilized, consult local dealers for the calculation of the power in Watt.
5.Please select thermal relay trip contact to prevent resistor over load. Use the contact to switch power off to the AC motor drive!
6.When using more than 2 brake units, equivalent resistor value of parallel brake unit can’t be less than the value in the column “Minimum Equivalent Resistor Value for Each AC Drive” (the
7.Please read the wiring information in the user manual of the brake unit thoroughly prior to
