1.
Fit the correct plug on the cable in accordance with local legislation and connection data. See
Technical Data on page 66 for the correct electrical connection.
2.
Connect the machine to a grounded wall outlet to avoid fire or electric shock.
•
The power cable must be free at all times, and nothing may be placed on it.
•
Immediately replace the power cable if damaged.
3.
Operating the machine with an incorrect direction of rotation results in damage to the pump,
in which case no vacuum can be created. After connecting the machine to a different three-
phase power supply, the direction of rotation should be checked again. If the direction of
rotation is incorrect, two phases in the plug must be interchanged.
