The compressed air connection is preset at the factory. Do NOT change the setting. In delivery
condition of the oven, this setting is protected by a cover with seal.
If the seal is broken, please inform BINDER Service to have the setting checked and to rein-
stall the cover with seal.
Notes when using inert gas:
When operating the VDL vacuum drying oven with inert gas, correctly follow the technical ventilation
measures, as described in the guideline BGI/GUV-I 850-0 on safe working in laboratories (formerly
BGR/GUV-R 120 or ZH 1/119 laboratory guidelines issued by the employers’ liability insurance associa-
tion) (for Germany).
During sweeping the area for electrical equipment with inert gas, the unit is supplied with an oxygen dis-
placing gas (e.g. N
2
). Inert gases in high concentrations are hazardous to health. They are colorless and
almost odorless and therefore practically imperceptible. Inhalation of inert gases can cause drowsiness up
to respiratory arrest. When the O
2
content of the air decreases below 18%, there is risk of death from lack
of oxygen. Any gas that might escape has to be led out via good room ventilation or a suitable exhaust
system.
WARNING
High concentration of inert gas.
Risk of death by suffocation.
∅
Do NOT set up units in non-ventilated recesses.
 Ensure technical ventilation measures.
 Respect the relevant regulations for handling these gases.
 When decommissioning the vacuum drying oven, shut off the inert gas supply: Close
valve (6).
4.5 Electrical connection
• The VDL vacuum drying oven comes with a fixed power connection cable that has a length of 1800
mm / 5.9 ft. and a shockproof plug. The socket must also provide a protective conductor.
• Unit fuse 10 Amp
• Power supply voltage 230 V (1N~) ± 10 %, 50/60 Hz
• Prior to connection and start-up, check the power supply voltage. Compare the values to the specified
data located on the unit’s type plate (left side of the unit, bottom right-hand, chap. 1.4).
• When connecting, please observe the regulations specified by the local electricity supply company as
well as the VDE directives (for Germany)
• Pollution degree (acc. to IEC 61010-1): 2
• Over-voltage category (acc. to IEC 61010-1): II
CAUTION
Danger of incorrect power supply voltage.
Damage to the equipment.

Check the power supply voltage before connection and start-up.
 Compare the power supply voltage with the data indicated on the type plate.
See also electrical data (chap. 19.2).
To completely separate the unit from the power supply, you must disconnect the power plug.
Install the unit in a way that the power plug is easily accessible and can be easily pulled in case
of danger.
