Installation Recommendations

INSTALLATION RECOMMENDATIONS

•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.
