The Leybold SOGEVAC Neo D have been designed for safe and efficient
operation when used properly and in accordance with these Operating
Instructions. It is the responsibility of the user to carefully read and strictly observe
all safety precautions described in this section and throughout the Operating
Instructions. The SOGEVAC Neo D must only be operated in the proper
condition and under the conditions described in the Operating Instructions.
ATEX Cat 3 vacuum pumps have been specifically designed and manufactured to
meet the requirements for Equipment-group II Category 3 of the "ATEX" Directive"
i.e. Directive 2014/34/EU concerning equipment and protective systems intended
for use in potentially explosive atmospheres. Pumps are designed for indoor use
without condensation. Do not step on the pumps.
SOGEVAC pumps are not designed:
• for pumping of dusty, aggressive, corrosive, flammable, explosive or
pyrophoric gases or gases mixtures
• for pumping of oxygen or other highly reactive gases with a greater
concentration than atmospheric concentration (>20%) unless specific P/N and
PFPE fluid are used
• for working in flammable, explosive (unless ATEX pumps are used) or dusty
environment.
• For continuous duty above 800 mbar abs
For all these cases, special materials must be used. In case of doubt, please
contact Leybold.
See also the limits of use indicated in the CE declaration of conformity.
Never expose part of the body to the vacuum. There is a danger of injury. Never
operate the pump with an open and thus accessible inlet. Vacuum connections as
well as oil filling and oil draining openings must not be opened during operation of
the pump. When operating pump is hot and some surfaces could reach a
temperature higher than 80°C (176°F). There is a risk of burn by touching.
Depending on the process involved, dangerous substances and oil may escape
from the pump. Take the necessary safety precautions!
When working on the pump system always observe the Operating Instructions.
Disconnect the unit from the power supply before starting any work.
Pump must not be operated above 2000 m sea level
High electric voltages! When touching parts at high electric voltages, there is the
risk of suffering severe injuries by an electric shock! Covers marked with this
symbol must only be opened by trained electricians after having reliably
deenergized (lockout/tagout) the equipment. Always operate the pump with a
properly connected protective earth conductor and make sure that the motor & FC
connection box are closed.
Use only the Leybold frequency converter for the pumps equipped with one.
Lay the connecting lines so that these cannot be damaged. Protect the lines
against humidity and contact with fluids. Avoid thermally stressing the lines by
unfavorable laying. Provide strain relief for the connecting lines so that the plugs
and the line connectors are not subjected to excessively high mechanical
stresses.
Lay electric feed lines so that there is no risk of tripping over these.
