Electrical Installation
The plumbing installation must be complete before the electrical installation work is done.
If no external motor protector is present, connection blocks P1 and P2 must be connected together (strapped).
If the circulation pump is fitted with a protective motor auxiliary relay, this must be connected to connection blocks P1 and P2;
refer to the schematic diagram for the respective voltage and number of phases. When the motor protector is engaged,
the circuit shall be closed with a floating-voltage change-over contact.
Make sure that the connecting wire cannot come into contact with the hot parts of the element.
