VDL (E3.1) 10/2020 Page 15/196
1.7.1.1 Aeration / ventilation of the installation site
NOTICE
Danger of overheating due to lack of aeration.
Damage to the chamber.
∅ Do NOT install the chamber in unventilated recesses.
Ensure sufficient ventilation for dispersal of heat.
Observe the prescribed minimum distances when installing the chamber (chap. 5.1)
The vacuum drying ovens were constructed in accordance with the applicable VDE regulations and were
routinely tested in accordance with VDE 0411-1 (IEC 61010-1). The production underlies an internal mon-
itoring according to ATEX Directive 2014/34/EU appendix VIII.
For the user there is no risk of temporary overvoltages in the sense of EN 61010-1:2010.
1.7.1.2 No installation in potentially explosive areas of Zone 1 or 0
Even when the equipment is used properly, there exists a residual risk of explosion that cannot be excluded,
particularly in relation to the environment of the chamber. To minimize this risk, strictly observe the legal
regulations about how to select an appropriate location. Do not install and operate the vacuum drying oven
VDL in occasionally or continuously / for long periods / frequently potentially explosive areas.
DANGER
Explosion hazard due to combustible dusts or explosive mixtures in the vicinity of
the equipment.
Serious injury or death from burns and / or explosion pressure.
∅ Do NOT operate the chamber in in occasionally or continuously / for long periods / fre-
quently potentially explosive areas. It is not intended for installation in a zone 1 or 0.
KEEP combustible dusts AWAY from the equipment
Make sure that air-solvent mixtures are NOT occasionally or continuously / for long pe-
riods / frequently in the vicinity of the equipment.
Reliably prevent spreading of an explosive atmosphere to unprotected areas (see chap.
3.5).
Strictly observe the relevant legal regulations about how to select an appropriate loca-
tion.
1.7.1.3 Equipotential bonding according to the grounding concept
The walkable installation and operating surface of the chamber must be conductive. This installation and
operating surface must be connected to the vacuum drying oven according to the grounding concept (chap.
6.8). Cyclic measurements of the equipotential bonding are required.
DANGER
Explosion hazard by electric sparking due to missing or improperly implemented
equipotential bonding.
Serious injury or death from burns and / or explosion pressure.
Connect all equipment elements in the installation and operating area (VDL / pump
module / pump) with the conductive surface and/or with each other. Proceed according
to the grounding concept (Chap. 6.8).
Measure the equipotential bonding prior to commissioning the equipment.
Provide cyclic measurements of the equipotential bonding.
