Lightning protection device

The building in which the vacuum drying oven is installed must have a lightning protection system. All
internal connections in the operator's building must contain lightning protection in accordance with
EN/IEC 62305-3.
Lightning protection measures must be taken in order to prevent melting and spraying effects. The opera-
tor's zone classification shall be used to plan lightning protection measures. The lightning discharge paths
must be designed so that heat or ignitable / spray sparks cannot become the ignition source for an explo-
sive atmosphere.

Installation and connections

The chambers may only be installed, connected, and commissioned by specialist personnel. Specialist
personnel must have knowledge of the types of ignition protection and regulations and ordinances for
equipment used in hazardous areas (Ex areas).

done in the absence of solvents and under extraction (technical ventilation).
The rack holders can only be removed from the chamber after removing the expansion racks.
Rack holder installation: Align the rack holders to the cams in the bottom of the inner chamber and insert
them.
Prior to insertion check the expansion racks and rack holders for corrosion . If corrosion is detected, the
affected element must not be used.
Explosion hazard due to creation of mechanical sparks in an explosive atmosphere.
Serious injury or death from burns and / or explosion pressure.
 Insert or remove the expansion racks and rack holders only in the absence of solvent.
 Insert or remove the expansion racks and rack holders only with active extraction
(technical ventilation).
 Prior to inserting the expansion racks and rack holders, check them for corrosion.
