Страница: 23 / 52

5.5 Connecting the fore-vacuum side
WARNING
Risk of crushing from rotating parts
Fingers and hands may be caught by rotating pistons within the connection flange. This results in se-
vere injuries.
► Keep limbs out of the reach of the roots pump.
CAUTION
Danger of injury from bursting as a result of high pressure in the exhaust line
Faulty or inadequate exhaust pipes lead to dangerous situations, e.g. increased exhaust pressure.
There is a danger of bursting. Injuries caused by flying fragments, the escaping of high pressure, and
damage to the unit cannot be excluded.
► Route the exhaust line without shut-off units.
► Observe the permissible pressures and pressure differentials for the product.
► Check the function of the exhaust line on a regular basis.
Procedure
1. Choose a minimum pipe cross section equal to the nominal diameter of the pressure flange.
2. Clear welded lines of any tinder, loose parts or similar before installation.
3. Route the pipes so that no mechanical tension can act on the roots pump or the backing pump.
4. Install a bellows in the piping if necessary.
5. Ensure that mating flanges are in a parallel position.
6. Install the pipes downward from the roots pump, so that condensate does not flow back into the
roots pump.
7. Install a condensate separator if necessary.
8. If an air trap is created in the system, then install a condensate drain facility at the lowest point.
5.6 Connect to mains power supply
DANGER
Danger to life from electric shock
Touching exposed and voltage-bearing elements causes an electric shock. Improper connection of
the mains supply leads to the risk of touchable live housing parts. There is a risk to life.
► Before the installation, check that the connection leads are voltage-free.
► Make sure that electrical installations are only carried out by qualified electricians.
► Provide adequate grounding for the device.
► After connection work, carry out an earthed conductor check.
WARNING
Risk of fatal injury due to electric shock on account of incorrect installation
The device's power supply uses life-threatening voltages. Unsafe or improper installation can lead to
life-threatening situations from electric shocks obtained from working with or on the unit.
► Ensure safe integration into an emergency off safety circuit.
► Do not carry out your own conversions or modifications on the unit.
CAUTION
Danger of injury from moving parts
After a power failure or a standstill as a result of overheating, the motor restarts automatically. There
is a risk of injury to fingers and hands if they enter the operating range of rotating parts.
► Safely disconnect motor from the mains.
► Secure the motor against reactivation.
► Dismantle the vacuum pump for inspection, away from the system if necessary.
