connection)
Note:
 The current-carrying capability of the DC bus copper bar of a unit is only 100A or 200A. For details about the
specification, see section 3.6 Product ratings. The current on the DC bus copper bar cannot exceed its
current-carrying capability.
 There are two types of external bus terminals: 100A and 200A. Please select the terminals according to the current
requirements, and note that the current on each terminal cannot exceed its current-carrying capacity.

 -10–+50° C
 When the temperature exceeds 40° C, derate 1% for every increase of 1° C.
 Do not use the VFD when the ambient temperature exceeds 50° C.
 In order to improve reliability, do not use the VFD in the places where the
temperature changes rapidly.
 When the VFD is used in a closed space, such as control cabinet, use a cooling
fan or air conditioner for cooling, preventing the internal temperature from
exceeding the temperature required.
 When the temperature is too low, if you want to use the VFD that has been idled
