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).
• 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.
• 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.
