3.4  Electrical connection

Risk due to high voltages

 

Death or severe injury caused by an electric shock! 
The electrical connections must only be provided by a trained electrician as 
specified, for example, by the regulations EN 50110-1. Note the national 
regulations of the country in which the equipment is being operated.

During all connection work, the mains power supply lines must be de-ener-
gised (lockout/tag out). In order to prevent the pump from running up 
unexpectedly after a mains power failure, the pump must be integrated in 
the control system in such a way that the pump can only be switched on 
again manually. This applies equally to emergency cut-out arrangements.

Observe Safety Information 0.2.
