Fastening the connection cables
à
Fasten the connection cables so that
– the cables do not come into contact with movable or hot parts.
– the cables cannot be worn or damaged on sharp corners or edges
– no tensile and pressure forces are exerted on the connection point
of the cables (strain relief)
The three-phase motors are suitable for operation with frequency
converters.
Connecting the pump
1. Compare the data of the supply voltage with the details on the motor
type plate. See the pump type plate for the maximum current con-
sumption of the pump.
For the permissible deviation of the supply voltage, see operating
instructions for motor.
Set the direction of rotation according to the arrow on the fan hood
(see
7.1 Installing the pump and operating instructions for the mo-
tor).
2. Connecting the motor cable:
The electrical connection is established via three flat plugs
(each 6.3 x 0.8 for L1, N and PE).
7.3 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 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
4
Technical data ).
Pump discharge
à
If the pump is used as a vacuum pump, safely (with respect to medium
and noise) drain the hot pump discharge that may, under certain cir-
cumstances, occur at the pneumatic outlet of the pump.
