*Indicating that the power level variable frequency drive brake unit can be optionally built-in; Taking 18.5kW as an example: the model without brake unit is GK800-4T18.5, and the model with brake unit is GK800-4T18.5B. The brake resistor needs to be externally equipped, as shown in Table 3-3.
**The input current after configuring the DC reactor. GK800-4T90 and above products are equipped with an external DC reactor at the factory. Please make sure to connect the reactor for use, otherwise it will cause the product to malfunction.
