WARNING! Risk of electric shock!
Danger from electrical current must be eliminated.
• All electrical work must be carried out by a qualified electrician.
• Before any electrical connections are made, the pump must be de-energised and
protected against unauthorised restarting.

main pipe and/or the pump housing or motor housing.
• The pump/system must be earthed in accordance with local regulations. A residual
current device may be used for additional protection.
• Unscrew the cap from the terminal box.
• Remove the cap.
