For water-cooled rectifier units
2.
To ensure that water-cooled rectifier units are installed reliably and in good heat dissipation, pay attention
to the following:
 The unit must be installed and used in a cabinet.
 A minimum ventilation clearance must be kept from the top and bottom of the rectifier unit to ensure
good heat dissipation. See Figure 3-7.

Cabinet inlet and outlet area
3.
To ensure good heat dissipation of the inverter unit, design the air inlet and outlet as follows:
Air inlet area formula: S
S indicates the system ventilation area;
S indicates the each module ventilation area with a unit of cm
module
Air outlet area formula: S
For details about the air volumes required by the units, see Table 3-1.

3.3.5.2 Cabinet requirements
The cabinet frame must be strong enough to withstand the weight of components, control circuits and
1.
other equipments installed in it.
The cabinet must provide contact-proof shields for the powered circuits, and meet the requirements in
2.
terms of dust and humidity.
To facilitate installation, it is recommended to leave sufficient space around the device: space for
3.
cooling air flow, necessary clearance, and space required by the cable and cable support structure. Do
