4.5.2 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: nXRi pumps ,
(10)) with an appropriate cord set. Refer to Table: Recommended cord sets .
The pump must be grounded through the conductor of the mains input connector.
4.6 Connection for remote control and monitoring
To operate the pump with parallel or serial control, the 15-way D-type connector must
be used ( Figure: nXRi pumps , (8)).
Refer to Figure: Logic interface connections - analogue speed control for details of the
logic interface pins.
The pump is also equipped with a front USB port for service purposes using serial
communication. This connector cannot be used for pump operation, but for setting and
reading parameters and for pump monitoring.
