laboratories, issued by the employers’ liability insurance association; Industrial Safety Regulation (Be-
trSichV); Ordinance on Hazardous Substances (GefStoffV); Technical Regulations on Industrial Safety
and Health (TRBS 1201 Part 1).
The central element of the Industrial Safety Regulation is the risk assessment performed by competent
personnel which enables an employer to evaluate risks that may arise before using work equipment and
to derive necessary and suitable tests and measures.
Explosion protection plan
The explosion protection plan to be created by the operator represents the entirety of the technical and
organizational measures for explosion protection determined and specified on the basis of the risk asses-
sment. In accordance with ATEX Operational Directive 1999/92/EC, these measures serve
•to prevent the formation of or to limit explosive atmospheres or to limit hazardous explosive mixtures
•to avoid the combustion of explosive atmospheres
•to limit the spread of an explosion and to minimize its effects on personnel in order to ensure the
health and safety of employees
The explosion protection document serves to document the results of the risk assessment in accordance
with § 6 Para. 9 GefStoffV (for Germany).
BINDER GmbH is only responsible for the safety features of the chamber provided skilled electricians or
qualified personnel authorized by BINDER perform all maintenance and repair, and if components rela-
ting to chamber safety are replaced in the event of failure with original spare parts.
To operate the chamber, use only original BINDER accessories or accessories from third-party suppliers
authorized by BINDER. The user is responsible for any risk caused by using unauthorized accessories.
1.7.1 Safety instructions on installation and ambient conditions of 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 mo-
nitoring 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
periods / frequently in the vicinity of the equipment.
Reliably prevent spreading of an explosive atmosphere to unprotected areas (see chap.
3.6).
Strictly observe the relevant legal regulations about how to select an appropriate locati-
on.

VDL (E3) 09/2019 Page 18/234
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. 6.6). 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. 6.6).
Measure the equipotential bonding prior to commissioning the equipment.
Provide cyclic measurements of the equipotential bonding.
1.7.1.4 Accessibility to the disconnection from the power grid
To completely separate the chamber from the power supply, you must disconnect the power plug. Install
the chamber in a way that the power plug is easily accessible and can be easily pulled in case of danger.
1.7.1.5 Technical ventilation (extraction)
The operator shall provide active extraction (technical ventilation according to country-specific regulations
(TRBS 2152 Part 2 for Germany) before commissioning the chamber. Extraction must include the entire
installation area of the vacuum drying oven and a vacuum pump; in addition, extraction must be provided
on the floor behind the chamber. Extraction must be active during the entire chamber operation. Operati-
on, loading and unloading of the loading material and removal of the filled condensate catchpot of the
pump must always take place under technical ventilation. If the technical ventilation fails, automatically
switch off power to the chamber.
This will prevent spreading of an explosive atmosphere to unprotected areas (see chap. 3.6).
DANGER
Explosion hazard due to the spread of an explosive atmosphere to unprotected
areas and ignition due to electric sparking or hot surfaces.
Serious injury or death from burns and / or explosion pressure.
Provide active suction (technical ventilation according to country-specific regulations
(TRBS 2152 Part 2 for Germany) prior to commissioning the chamber.
Extraction must include the entire installation area of the vacuum drying oven; in additi-
on, extraction must be provided on the floor behind the chamber.
Make sure that the chamber is automatically turned off if the technical ventilation fails.

VDL (E3) 09/2019 Page 19/234
1.7.2 Safety instructions on vacuum supply
Prior to commissioning the chamber make sure that all relevant national and international regulations are
observed. Within the European Union, units that will be operated in potentially explosive areas have to
meet the requirements of ATEX Directive 2014/34/EU.
If combustible solvent is introduced into the drying chamber, the vacuum pump must be constructed in a
suitable explosion-proof manner.
Observe the safety instructions of the pump manufacturer.
1.7.2.1 Selection and location of a suitable pump
The mixtures extracted from the inner chamber must be carried away making sure that there is no danger
by ignition of these atmospheres. Sparking in the pump motor or the switching elements, electrostatic
discharges, as well as hot pump parts can ignite solvent vapors in the event of an error. To minimize this
risk, use an ATEX Directive 2014/34/EU compliant vacuum pump suitable for suction from Zone 0 or 1
and, if appropriate, from the zone of its installation site. See chap. 6.4.1.
DANGER
Explosion hazard due to the spread of an explosive atmosphere to unprotected
pump parts and ignition due to electric sparking on the pump motor or switching
elements, electrostatic discharges, or hot surfaces.
Serious injury or death from burns and / or explosion pressure.
Use only suitable, explosion-proof pumps. See chap. 6.4.1.
Operate the pump in a stationary position and secure it so it is immobile.
Make sure that the suction line to the vacuum connection (6) of the VDL is fixed and
conductive.
Ensure sufficient solvent condensation, e.g., in an exhaust waste vapor condenser, to
avoid that ignitable solvent concentrations are conducted from the pump. Otherwise,
the exhaust pipe after the pump must be fixed and conductive and suction must be do-
ne in an explosion-proof area.
Ensure equipotential bonding between the pump, the VDL vacuum drying oven and, if
appropriate, the pump module using the connections of the grounding conductors ac-
cording to the grounding concept (Chap. 6.6).
Confirm that the vacuum pump is designed for a gas inlet temperature corresponding to
the used drying temperature, or take appropriate measures to cool down the extracted
vapor before it enters the vacuum pump.
Use ATEX compliant vacuum pumps providing an integral protective device for the
pump OR Install a current-dependent, delayed protective device for the pump (for the
triggering time of this protective device, see the manufacturer’s specifications). The pro-
tective and monitoring device must not be able to turn on independently again or be re-
leased.
Use ATEX compliant vacuum pumps providing an integral explosion proof switch OR
make sure that the switch gear box is either installed outside the hazardous area or that
it is explosion proof.
The ATEX compliant vacuum pumps offered by BINDER provide an integral protective device
for the pump and an integral explosion proof switch.

VDL (E3) 09/2019 Page 20/234
1.7.2.2 Observing the permissible gas inlet temperature
Confirm that the vacuum pump / vacuum system is designed for a gas inlet temperature corresponding to
the used drying temperature, or take appropriate measures to cool down the extracted vapor before it
enters the vacuum pump / vacuum system. If the gas inlet temperature is too high and then becomes
even warmer by compression in the pump, the resulting temperature (of the gas-solvent mixture inside
the pump) could exceed the solvent’s temperature class and auto-ignition temperature. The ATEX com-
pliant vacuum pumps offered by BINDER are designed for a gas inlet temperature of 40 °C / 104 °F
max. Do NOT exceed this temperature.
DANGER
Fire and explosion hazard by exceeding the auto-ignition temperature of the solvent
due to excessive gas inlet temperature
Damage to the vacuum pump. Serious injury or death from burns and / or explosion
pressure.
∅Do NOT exceed the maximum gas inlet temperature of the pump (ATEX compliant
vacuum pumps from BINDER: 40 °C).
When operating with a higher set-point temperature take appropriate measures to cool
down the extracted vapor before it enters into to the vacuum pump.
1.7.2.3 Technical Ventilation (extraction)
When manipulating the vacuum pump (removing the filled condensate catchpot of the pump) or in the
event of an error (e.g. dropping or spilling the filled condensate catchpot) spreading of an explosive atmo-
sphere to unprotected parts of the pump or the vacuum drying oven would be possible.
The operator must provide active extraction (technical ventilation according to country-specific regulations
– TRBS 2152 Part 2 for Germany) prior to commissioning and manipulating the vacuum pump. Extraction
must include the entire installation area of the vacuum drying oven, the pump and, if appropriate, the
pump module, in addition, extraction must be provided on the floor behind the chamber. Handling the
pump always takes place under technical ventilation.
This will prevent spreading of an explosive atmosphere to unprotected chamber parts other than the defi-
ned area (see Chap. 3.6).
DANGER
Explosion hazard due to the spread of an explosive atmosphere to unprotected
parts of the pump or the vacuum drying oven and ignition due to electric sparking
or hot surfaces.
Serious injury or death from burns and / or explosion pressure.
Provide active suction (technical ventilation according to country-specific regulations
(TRBS 2152 Part 2 for Germany) prior to commissioning the vacuum pump.
Extraction must include the entire installation area of the vacuum drying oven, the pump
and, if appropriate, the pump module; in addition, extraction must be provided on the
floor behind the chamber.
When using the pump module, connect an extraction system to the provided exhaust
port as described in the mounting instructions of the pump module (Art. no. 7001-0137).
