WARNING
Risk of danger to life through missing mains disconnection device
The vacuum pump and electronic drive unit are not equipped with a mains disconnection device
(mains switch).
►Install a mains disconnection device according to SEMI-S2.
►Install a circuit breaker with an interruption rating of at least 10,000 A.
Risks during operation
WARNING
Danger of cut injuries from unexpected start up.
The use of mating plugs of the electronic drive unit (accessories) enables the automatic run-up of the
vacuum pump as soon the power is turned on. Attaching mating plugs before or during the installa-
tion leads to the movement of parts hence the risk of cut injuries by sharp-edged in the exposed high
vacuum flange.
►Only connect mating plugs after the mechanical installation.
►Only switch on the vacuum pump immediately prior to operation.
WARNING
Risk of burns in case of contact with hot surfaces
For the operator's safety, the products are designed to avoid thermal risk. Depending on the applica-
tion, the conditions of use generate high temperatures which require extra caution from users (surfa-
ces > 65 °C).
►Pay attention to the marking of hot surfaces indicated by safety labels.
►Wait for the part to cool completely before working on the product.
►If necessary, wear protective gloves in accordance with standard EN 420.
Risks during maintenance
WARNING
Danger to life from electric shock during maintenance and service work
The device is only completely de-energized when the mains plug has been disconnected and the
vacuum pump is at a standstill. There is a danger to life from electric shock when making contact with
live components.
►Before performing all work, switch off the main switch.
►Wait until the vacuum pump comes to a standstill (rotation speed =0).
►Disconnect all connection cables.
►Remove the mains plug from the device.
►Secure the device against unintentional restarting.
Recycling and disposal
WARNING
Health hazard through poisoning from toxic contaminated components or devices
Toxic process media result in contamination of devices or parts of them. During maintenance work,
there is a risk to health from contact with these poisonous substances. Illegal disposal of toxic sub-
stances causes environmental damage.
►Take suitable safety precautions and prevent health hazards or environmental pollution by toxic
process media.
►Decontaminate affected parts before carrying out maintenance work.
►Wear protective equipment.
