4.5.1 Connect the electrical supply
WARNING: PROTECTIVE EARTH
Risk of electric shock. Make sure that the pump and electrical cables are protected
against earth (ground) faults. It is recommended that a protective earth (ground)
conductor (with a cross sectional area of 2.5 mm
2
/ 13 AWG be fitted to the
protective earth (ground) stud.
Make the electrical connection to the pump mains connector port (
on page 8, item 10) with an appropriate cord set. Refer to
on page 35.
The pump must be grounded through the earth (ground) conductor of the IEC60320
connector.
4.6 Connect the system
4.6.1 Purge gas connection
WARNING: HAZARDOUS SUBSTANCES
Risk of explosion. The pump is intended for clean applications only. It is not suitable
for use with hazardous production materials.
Make sure that the nitrogen supply and the purge supply are as the values in
on page 15 to prevent a blockage.
Refer to
on page 8, item 12 for the location of the nitrogen
purge port.
Gas purge is used for movement of inert light gases, such as helium.
4.6.2 Connection for remote control and monitoring
To operate the pump with parallel or serial control, use the 15-way D-type connector.
Refer to
Figure: Logic interface connection
on page 25 for details of the logic interface
pins.
4.6.3 Connect the logic interface to the control equipment
The pump can be controlled, with a hardware parallel control interface through
commands sent over a serial interface. Refer to
Parallel and serial control mode
on page
24 for more information.
To control the pump through the serial interface, please contact us for information.
4.7 Additional safety equipment
If necessary, install appropriate measurement equipment in the nitrogen supply
pipeline. This is used if you need to monitor the total flow rate of nitrogen to the pump.
