4.4.2 Connect the electrical supply
WARNING: PROTECTIVE EARTH CONNECTION
Risk of electric shock. Make sure that the pump and electrical cables are suitably
protected against earth (ground) faults. We recommend you attach a protective earth
(ground) conductor (with a cross sectional area of 2.5 mm
2
/14 AWG) to the protective
earth (ground) stud.
Make the electrical connection to the pump mains connector port (Figure:
General view, (10)) with an appropriate cord set. Refer to Table: Mains
cables.
The pump must be grounded through the conductor of the mains input
connector.
4.5 Connection for remote control and monitoring
To operate the pump with parallel or serial control, the two SUB-D 9 pin
connectors can be used. The female connector (X104) is for serial
connection, the male connector (X1) is for parallel connection (Figure:
General view, (8)).
Refer to Analogue speed control on page 29 for details of the logic interface
pins.
