4-3
AC30V Variable Speed Drive
MOUNTING THE DRIVE
These units are not suitable for wall mounting. They must be mounted vertically inside an additional enclosure. Depending on required level of
EMC compliance refer to Appendix C "Compliance".
Note: Frame H, J & K only
These models are heavy and will require two people to lift, or the use of a fork lift to install it. The product will stand vertically on flat surfaces.
VENTILATION
The drive gives off heat in normal operation and must therefore be mounted to allow the free flow of air through the ventilation slots and heatsink.
Maintain minimum clearances for ventilation as given in the tables below to ensure adequate cooling of the drive, and that heat generated by
other adjacent equipment is not transmitted to the drive. Be aware that other equipment may have its own clearance requirements. When
mounting two or more AC30V units together, these clearances are additive. Ensure that the mounting surface is normally cool.

Cubicle-Mount Product/Application
(Europe: IP2x, USA/Canada: Open Type).
The drive must be mounted in a suitable cubicle.
