Goodrive880 Series Active Rectifier Hardware Manual
3. Installation space requirements for A8i active rectifier units
To ensure that the active rectifier unit is installed reliably and in good heat dissipation, pay attention to the
following:
A. The active rectifier unit must be installed and used in a cabinet.
B. A minimum ventilation clearance must be kept from the top and bottom of the active rectifier unit to
ensure good heat dissipation. See Figure 3-12.
C. Both sides of each unit are designed with air baffle and sealing sponge for isolation to prevent the hot
air at the unit top outlet from circulating inside the cabinet and ensure that the heat of the unit is
discharged from the heat dissipation holes at the cabinet top outlet cover. See Figure 3-12.

To ensure good heat dissipation of the active rectifier, design the air inlet and outlet as follows:
Air inlet area formula:
S = (1.5~2.0) x (S

S: System ventilation area
S : Each module ventilation area (cm

Air outlet area formula: S
For details about the air volumes required by the active rectifier, see Table 3-1.
