6.3.1
ELECTRICAL CONNECTION
6.4
SWITCH ON PUMP
The pump is switched on via switching elements in the application. After switching on, the pump goes directly into
normal operating mode. There are no subordinate operating modes for setup, maintenance or troubleshooting.
The pump must not be switched on until it has been properly set up, the electrical installation has been properly
installed and the media lines have been connected.
6.5
NORMAL OPERATION
In normal operation, the pump operates fully automatically within its physical limits, according to the customer's
control.
6.6
SWITCH OFF PUMP
1.
Shutdown
To switch off, the pump must be shut down from the application and secured against being switched on
again. In addition, a warning sign must be attached to the mains disconnection device.
All electrical equipment must be individually disconnected. Maintenance and servicing activities are strictly
prohibited during operation or when the pump is switched on.
2.
Disconnection from the power supply
A verifiably qualified electrician switches the motor free and disconnects it. After carrying out the 5 safety
rules, non-qualified electricians may also carry out activities on the pump.
After completing the activities, follow the instructions in the chapter 6.7.
Connecting the motor
The motor must be connected according to the connection diagram (see
terminal box cover or instruction leaflet in the terminal box).
The permissible connection types of the motor can be found on the
motor type plate.
The motor must be protected by a motor circuit breaker for which the
service factor (SF) must be taken into account. Operation without an
appropriate fuse is prohibited.
Approved direction of rotation of the pump
Before commissioning, check whether the pump is rotating in the
prescribed direction (observe the direction of rotation arrow on the unit
cover). For this purpose, start the pump only briefly (max. 3 sec.), as
operation with the wrong direction of rotation will cause damage to the
pump.
If the pump does not run in the specified direction of rotation (view of
the motor fan wheel), this must be changed by swapping two connection
phases.
