5.3.1.5 Installing the pump set
NOTE
Make sure the pump set with the pre-assembled claw can easily be slipped over the
mounting bracket, threaded onto the guide rails and lowered down. If required,
alter the position of the crane during installation.
1. Guide the pump set over the suspension bracket/mounting bracket and slowly
lower it down along the guide rail(s).
The pump set attaches itself to flanged bend 72-1.
2. Attach the lifting chain/rope to hook 59-18.01 at the mounting bracket.
5.4 Electrical system
5.4.1 Information for planning the control system
For the electrical connection of the pump set observe the "Wiring diagrams" section.
(ð Section 9.3, Page 120)
NOTE
When laying a cable between the control system and the pump set's connection
point, verify that the number of cores is sufficient for the sensors. A minimum cross-
section of 1 mm² is required.
The motors can be connected to electrical low-voltage grids with mains voltages and
voltage tolerances to IEC 60038. The permissible tolerances must be observed.
5.4.1.1 Starting method
The pump set is wired for DOL starting.
Star-delta starting is technically possible, except for pump sets with a 4G1.5+2x1 or
7G1.5 power cable. (ð Section 9.3, Page 120)
For reducing the starting current autotransformers or soft starters can be used. For
selecting suitable devices observe the rated current of the motor.
At least three times the rated current is required for reliable start-up. The run-up
time must not exceed 4 seconds.
After start-up of the pump, a soft starter must always be bypassed.
