Electrical Connection - Binder vdl 23 Operating Manual

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 DGUV guidelines 213-850 on safe working in laboratories (formerly
BGI/GUV-I 850-0, BGR/GUV-R 120 or ZH 1/119, issued by the employers' liability insurance association)
(for Germany).
During sweeping the area for electrical equipment with inert gas, the chamber is supplied with an oxygen
displacing gas (e.g. N ). 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 drowsi-
ness up to respiratory arrest. When the O
from lack of oxygen. Any gas that might escape has to be led out via good room ventilation or a suitable
exhaust system.
High concentration of inert gas.
Risk of death by suffocation.
∅ Do NOT set up chambers 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).

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.
• Chamber 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 chamber's type plate (left side of the chamber, bottom right-hand, chap. 1.4).
• We recommend the use of a residual current circuit breaker.
• 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
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 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.
