VDL (E3.1) 10/2020 Page 69/196
NOTICE
Danger of incorrect power supply voltage due to improper connection.
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.
• When connecting, please observe the regulations specified by the local electricity supply company as
well as the VDE directives (for Germany). We recommend the use of a residual current circuit breaker.
DANGER
Electrical hazard due to shock after damage to the device due to pulling on the
electrical connection cable during transport.
Damage to the equipment. Deadly electric shock.
After transport, check the electrical power cable at the installation site to make
sure that it is connected correctly and securely.
∅ Do NOT operate the chamber if the power cable is damaged.
• Pollution degree (acc. to IEC 61010-1): 2
• Over-voltage category (acc. to IEC 61010-1): II
See also electrical data (chap. 28.3).
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.
A customer's emergency stop switch or a comparable power disconnector can also be used.
The chamber plug (power plug) is unprotected because it must be disconnected in case of an emergency
to completely separate the chamber from the power supply. Therefore, the electrical connection must be
established outside a zone.
DANGER
Explosion hazard due to sparking when disconnecting an electrical connection.
Serious injury or death from burns and / or explosion pressure.
Make sure that the electrical connection is located outside a zone.
Connect the plug outside the installation area of the VDL and the pump. Take into ac-
count the information on zone classification (chap. 3.5.2)
