Installation Involving Different Mains Voltages
This vacuum pump must be equipped with a mains circuit breaker in accord-
ance with requirements of EN 60204-1. It is recommended to use a circuit
breaker as main breaker which is suitable for isolation according to EN
60947-2 and is equipped with an operating handle which is lockable in the
OFF position and complies with the other requirements of EN 60947-3.
Remove the terminal cover of the motor and check the terminal block inside.
The wiring diagram is shown inside the terminal cover.
You can change between 100-115 V and 200-230 V connection by changing
the links. If you want to change the connection, remove the four nuts for the
power terminal and change the links as illustrated in Figure 3.4. Two links are
used at the 200-230 V connection. Connect the power cord through the
cable-gland on the bottom side of terminal blocks.
