Installation Recommendations

Mounting in a General-Purpose Metal Enclosure

To ensure sufficient air circulation when mounting an ATV58 TRX drive in a general-purpose enclosure, observe the following:

• Provide ventilation inlets and outlets in the enclosure (see the figure below).

free air flow	with fan and filter
	mounted on enclosure

•If the enclosure does not provide sufficient free air flow, install an enclosure ventilation fan with IP54/NEMA 12 filters to exhaust heat outside of the enclosure (see the figure above). The enclosure fan should have a greater fan flow rate than the drive controller fan flow rate listed in the table below.

ATV58 TRX Model	Fan Flow Rate
ATV58HU09M2, ATV58U18M2	Non-Ventilated
ATV58HU29M2, ATV58U18N4, ATV58U29N4, ATV58U41N4, ATV58U54N4	36 m3/hour	21 CFM
ATV58HU41M2	47 m3/hour	27.5 CFM
ATV58HU54M2, ATV58U72M2, ATV58U54N4, ATV58U72N4, ATV58U90N4	72 m3/hour	42 CFM
ATV58HU90M2, ATV58D12M2, ATV58D12N4, ATV58D16N4, ATV58D23N4	72 m3/hour	42 CFM
ATV58HD16M2, ATV58D23M2, ATV58D28N4, ATV58D33N4, ATV58D46N4	161 m3/hour	94 CFM
ATV58HD28M2, ATV58D33M2, ATV58D46M2, ATV58D54N4, ATV58D64N4, ATV58D79N4	343 m3/hour	200 CFM
ATV58HC10N4X	600 m3/hour	350 CFM
ATV58HC13N4X, C15N4X, C19N4X	900 m3/hour	525 CFM
ATV58HC23N4X, C25N4X, C28N4X, C31N4X, C33N4X	900 m3/hour	525 CFM

•If there is a possibility of condensation, keep the control supply switched on during periods when the motor is not running, or install thermostatically controlled strip heaters.

Mounting in a Type 12 or IP54 Metal Enclosure

Certain conditions may require Type 12 or IP54 protection, such as dust, corrosive gas, high humidity with the risk of condensation and dripping water. When mounting in a Type 12 or IP54 enclosure, follow the installation recommendations given on page 97.

If the enclosure is non-ventilated, use a stirring fan to circulate the air inside the enclosure to prevent hot spots from forming. With a stirring fan, the maximum temperature inside the enclosure can then be up to 60 °C (140 °F), although the current must be derated by 2.2% per °C above 50 °C. If condensation might form within the enclosure, keep the power supply switched on during periods when the motor is not running, or install thermostatically controlled strip heaters.
