Connecting the pump
1. Confirm that the power supply meets the parameters listed on the
pump nameplate. Refer to the pump nameplate for the rated current
consumption.
2. Connect the ground conductor to the pump motor.
3. Connect the motor wires.
4. Open the terminal box cover.
5. For pumps with capacitor motors:
Connect the electrical power cables to terminals L1 and N of the pump
motor.
6. Close the terminal box cover again.
6.3 Pneumatic connection
CAUTION
Personal injury or property damage through
ejected plugs
If not removed, the plugs on the pressure side of
the pump can be ejected during operation by the
resulting overpressure.
à
Remove the plugs during installation.
à
Wear appropriate personal protective equip-
ment.
Connected components
à
Only connect components to the pump that are designed for the pneu-
matic data and thermal requirements of the pump. (see Chapter
Pump discharge
à
If the pump is being used as a vacuum pump, safely (relating to the
medium and noise) discharge the possibly hot pump discharge via the
pneumatic outlet of the pump.
Connecting the pump
CAUTION
Risk of injury from mixing up suction side and
pressure side
Mixing up the suction side and pressure side can
result in breakage of connected components on
the suction side and pressure side.
à
Observe the marking of inlet and outlet on
the pump head.
1. Remove the protective plugs from the hose connection threads.
2. Connect the suction line and the pressure line (for mounting dimen-
).
3. Lay the suction line and pressure line with a descent so that no con-
densate can run into the pump.
Pneumatic noises can be reduced or dissipated by using a silencer
(see Chapter
).
