Making the cooling water connection
1. Connect the cooling water lines:
– Cooling water inlet
– Cooling water outlet
2. Ensure that the outlet is unpressurized.
3. Open the influx.
4. Open the bypass valve and at the same time fill the cooling system until cooling water is emitted
at the outlet.
5. Close the bypass valve.
6. If necessary, close the pressure switch and solenoid valve for monitoring and control of the cool-
ing water flow as prescribed in the supplier's documentation.
5.7 Establishing mains connection
DANGER
Danger to life from electric shock
Touching exposed and voltage-bearing elements causes an electric shock. Improper connection of
the mains supply leads to the risk of touchable live housing parts. There is a risk to life.
► Before the installation, check that the connection leads are voltage-free.
► Make sure that electrical installations are only carried out by qualified electricians.
► Provide adequate grounding for the device.
► After connection work, carry out an earthed conductor check.
CAUTION
Danger of injury from moving parts
After a power failure or a standstill as a result of overheating, the motor restarts automatically. There
is a risk of injury to fingers and hands if they enter the operating range of rotating parts.
► Safely disconnect motor from the mains.
► Secure the motor against reactivation.
► Dismantle the vacuum pump for inspection, away from the system if necessary.
