• The ATV58 TRX drive controller must be installed in a suitable environment. The environment around 

the drive controller must not exceed pollution degree requirements as defined in NEMA ICS-1 
Appendix A or EN60664/IEC60664.

• Install the drive controller vertically (±10°) with the power terminals at the bottom. Avoid placing the 

drive controller near any heat sources.

• Installation of a disconnect switch between the input line and the drive controller should be in 

accordance with national and local codes.

• Overcurrent protection is required. Refer to page 113 for recommended fuses.

• The figure to the left shows the minimum clearances required around each drive controller for 

unobstructed air flow. Also, leave at least 0.4 in. (10 mm) in front of the drive controller. These 
clearances should not be used as minimum enclosure size for proper thermal dissipation.

Depending on the ambient temperatures in which the ATV58 TRX controller is used, the clearance 
on the sides of the controller (dimension d in the drawing), and the particular ATV58 TRX model, 
removal of the protective cover or adding a fan may be required; see the table below for more 
information.

HU18N4 to HU90N4

≥

 50 mm (2 in)

No special precautions needed.

Remove the protective cover 
from the top of the controller 
(see graphic to the left). Degree 
of protection becomes IP20.

Add control card fan kit 
VW3A5882• (see page 33 for 
more information) and derate 
the rated operating current by 
2.2% for each °C over 50 °C.

< 50 mm (2 in)

Remove the protective cover 
from the top of the controller 
(see graphic to the left). Degree 
of protection becomes IP20.

HD12N4 to HD23N4

≥

 50 mm (2 in)

No special precautions needed.

Remove the protective cover 
from the drive (see graphic to 
the left). Degree of protection 
becomes IP20. Also derate the 
rated operating current by 2.2% 
for each °C over 40 °C.

Do not install where the ambient 
temperature exceeds 50 °C 
(122 °F).

< 50 mm (2 in)

Remove the protective cover 
from the top of the controller 
(see graphic to the left). Degree 
of protection becomes IP20.

VW3A5882• (see page 33 for 
more information) and derate 
the rated operating current by 
2.2% for each °C over 40 °C.

Do not install where the ambient 
temperature exceeds 50 °C 
(122 °F).
