WARNING
Faulty electrical connection on the IEC
box.
Contact with live parts may result in electric
shock. Fire hazard due to sparking or overload.
▪
The clamp of the IEC box must be
fixed correctly and screwed with the
securing element.
For block installation, AHT recommends e.g. the use
of a cable channel with sockets installed in or on it.
With floor mounting, the height of the cable channel
must reach maximum to the bottom edge of the rear
venting grille.
