Before installing the frequency converter, check the ambient air for liquids, particles, and gases. This is done by observing existing installations in this

environment. Typical indicators of harmful airborne liquids are water or oil on metal parts, or corrosion of metal parts.

Excessive dust particle levels are often found on installation cabinets and existing electrical installations. One indicator of aggressive airborne gases is

blackening of copper rails and cable ends on existing installations.

NB!

D and E enclosures have a stainless steel back-channel option to provide additional protection in aggressive environments. Proper ventilation is still

required for the internal components of the drive. Contact Danfoss for additional information.

The frequency converter has been tested according to the procedure based on the shown standards:

The frequency converter complies with requirements that exist for units mounted on the walls and floors of production premises, as well as in panels

bolted to walls or floors.

NB!

D and E frames have a stainless steel backchannel option to provide additional protection in aggressive environments. Proper ventilation

is still required for the internal components of the drive. Contact factory for additional information.
