Fig.29: Connecting the vibration sensor
We recommend the following settings for vibration monitoring with the (optional)
vibration sensor fitted at the factory:
▪ Alert triggered at v
eff
= 0.43in/s [11mm/s] (impeller typeE: v
eff
= 0.55in/s [14mm/
s])
– This vibration limit requires remedial action.
– In general, pump operation may continue until the causes of the change in
vibration level have been detected and remedies have been determined.
▪ Cut-out at v
eff
= 0.55in/s [14mm/s] (impeller typeE: v
eff
= 0.66in/s [17mm/s])
– If this vibration velocity is exceeded, continued pump set operation may
result in damage.
– Suitable action to reduce vibrations should be taken immediately, or the
pump set should be switched off.
5.4.2 Electrical connection
DANGER
Electrical connection work by unqualified personnel
Danger of death from electric shock!
▷ Always have the electrical connections installed by a trained electrician.
▷ Observe IEC 60364 regulations as well as any locally applicable regulations.
WARNING
Incorrect connection to the mains
Damage to the mains network, short circuit!
▷ Observe the technical specifications of the local energy supply companies.
CAUTION
Improper routing of power cables
Damage to the power cables!
▷ Never move the power cables at temperatures below -13 °F [-25 °C].
▷ Never kink or crush the power cables.
▷ Never lift the pump set by the power cables.
▷ Adjust the length of the power cables to the site requirements.
