Installation place: VM1000’s ingress protection is IP20. With power input
and high voltage output, it needs to be installed in indoors or equivalent
places. In order to keep away from accidental contact, invasion and prevent
rats and insects, it is suggested to install in the distribution box that has
sufficient protection effect or control box.
AC drive need to be installed on the surface of incombustible object such as
support, panel and solid architectural facade, and fix the AC drive with
screws and bolts.
Since a great amount of heat will be generated when VFD is running there
needs to have sufficient space around for heat dissipation. If necessary, it also
needs to equip with mandatory ventilation and heat dissipation devices.
Because the channel for ventilation and heat dissipation is designed
vertically, the VFD needs to be installed horizontally other than horizontally
or transversely.
