VDL (E3.1) 10/2020 Page 68/196
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 elements in the installation and loading area (VDL / pump module / pump)
with the conductive surface and/or with each other. Proceed according to the grounding
plan in chap. 6.8.
For installation of the pump module proceed acc. to the mounting instructions of the
pump module (Art. no. 7001-0137).
Make sure that the personal protective equipment (PPE) of the operating personnel is
implemented ESD protected. This applies also to gloves.
Before commissioning, measure the equipotential bonding after first setting up the VDL
and implementing all described measures for establishing the equipotential bonding.
Provide cyclic measurements of the equipotential bonding.
Always wear ESD-protected safety clothing when operating the chamber.
6.9 Electrical connection
The chambers are supplied ready for connection. They come with a fixed power connection cable of at
least 2000 mm / 78.74 in in length and a shockproof plug.

• The domestic socket must also provide a protective conductor. Make sure that the connection of the
protective conductor of the domestic installations to the chamber’s protective conductor meets the latest
technology. The protective conductors of the socket and plug must be compatible!
DANGER
Electrical hazard due to lack of a protective conductor.
Deadly electric shock.
Make sure that the power plug and power socket match and that the protective
electrical conductors of the chamber and domestic installation are securely con-
nected.
• 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 chamber side, bottom right-hand, see chap. 1.6).
