Lightning protection
Roof-mounted ATEX units must be protected by a proper lightning conductor that conforms to
the relevant statutory regulations (e.g. DIN VDE 0185). Lightning that strikes explosive
atmospheres always causes a fire. Lightning strikes and the resulting high temperatures form
an ignition source. Risk of fire
Hot surface
Take into account that certain ducting (e.g. near the heater) might reach temperatures of up to
110°C, depending on the atmosphere. Such high temperature can cause spontaneous ignition.
Risk of fire
5. Assembly of unit
For assembly/disassembly, observe all instructions for your various unit elements in this
manual. The unit must be assembled/disassembled by authorised specialist technicians in
accordance with the German Industrial Health and Safety Ordinance.
5.1.Preparation of unit assembly
Two standard units that are not designed for installation one on top of the other must be
positioned side by side.
To close the gaps between the unit sections, seal them with the supplied sealing tape before
tightening the screw connections. Prior to applying the sealing tape, clean and degrease the
relevant surfaces.
In hygiene units, seal the grooves of the section joints at the inside of the base with a sealant
that is resistant to disinfectants. This must be done in the course of the machine assembly on
site.
In weatherproof units, the gaps between the individual unit sections must be sealed after
assembly with the supplied sealant.
