Install Instructions

Specific recommendations for mounting in an enclosure
Note: The following only applies to ATV212HpppM3X and ATV212HpppN4 drives.
Minimum air flow rates
If you are installing the drive in a Type 1 enclosure, provide forced ventilation at a rate at least equal to the value
listed below each drive.
Sealed metal enclosure
The drive must be mounted in a dust and damp proof enclosure in certain environmental conditions, such as
dust, corrosive gases, high humidity with risk of condensation and dripping water, splashing liquid, etc.
This enables the drive to be used in an enclosure where the maximum internal temperature reaches 50°C.
When mounting the drive inside an UL Type 12 or IP54 enclosure, follow these ventilation instructions:
 Observe the minimum clearance distances shown on page 40.
 If necessary, install a stirring fan to circulate the air inside the enclosure, to help prevent hot spots in the drive,
and to distribute the heat uniformly to surfaces used for convection cooling.
Observe the mounting recommendations de-
scribed on page 40.
To help ensure proper air circulation in the drive:
 Fit ventilation grilles.
 Check that there is sufficient ventilation. If there is not, install a forced
ventilation unit with a filter. The openings and/or fans must provide a
flow rate at least equal to that of the drive fans (see below).
 Use special filters with UL Type 12/IP54 protection.
 Remove the blanking cover from the top of the drive, see page 41.

NOTICE
RISK DUE TO CONDENSATION
Where condensation is possible, keep the drive powered up when the motor is not running, or install
thermostatically controlled strip heaters.
Failure to follow these instructions can result in equipment damage.
