2.8 INFORMATION ON RESIDUAL RISKS
The pump is built according to the current state of the art and the recognised safety regulations. When using the
pump, health hazards for persons directly working with the pump and third parties cannot be excluded.
2.9 SAFETY INSTRUCTIONS
The hazards and risks in the respective phases of the pump's life are described below. The following hazard warnings
must be observed.
Danger to life due to electric shock / Personnel qualification
Work and tasks on the electrical system may only be carried out by qualified electricians who can prove that
they have successfully completed a recognised training course in the relevant specialist field and have been
instructed in the technical features of the pump.
The performance of electrical work, including the simplest auxiliary activities, is prohibited without exception
for persons who do not fulfil the above conditions.
To perform tasks and activities on the pump's electrical system, work must be carried out in accordance
with the five safety rules according to DIN VDE 0105.
Danger to life due to electric shock / Measures in case of damage to the electrical installation
Damage to the electrical installation and contact with live parts can be life-threatening.
The following measures are therefore mandatory:
• In the event of damage to the electrical installation, switch off the pump immediately and notify the
responsible office.
• A repair by a qualified electrician must be arranged.
Danger to life due to unexpected start-up / countermeasures
The following steps are mandatory when preparing for maintenance and servicing activities:
1. Switch off the pump and all attached assemblies.
2. Disconnect the pump from the supply voltage and proceed according to the five safety rules
(VDE105).
3. Disconnect the pump from the air supply.
Fire and danger to life due to insufficient distances to neighbouring parts
If the pump is enclosed, minimum distances from the product must be maintained to prevent potential fires.
Information on minimum distances can be found in the chapter 6.
Danger to life due to arcing and creepage path formation when disconnecting plug connections
Always switch off the power supply before disconnecting any plug-in connections.
