The max. sound pressure level of 54 dB(A) for this configuration
may develop when all four pumps are running under full load
conditions.
For noise characteristics of the pumps refer to the pumps’
Operating Instructions.
On units with acoustic cladding the noise emission of the unit is
reduced by 7 dB(A).

Connection to power supply
6.1
Electric wiring
All work marked with the symbol
must be performed
by a qualified electrician or a duly trained, experienced
person.
6.2
Power supply cable
A 3+PE wire power supply cable is required for the control
cabinet.
All connections shall be effected in accordance with the technical
specifications issued by the local energy supply company.
6.2.1 Sizing the power supply cable
The cross-section of the power supply cable must be sized for
the total rated power requirement.
6.3
Protective measures
- Neutralization (4-wire system) PE and N connected
- Earthing (5-wire system) PE and N separate
- Earth leakage circuit breaker
6.4
Temperature requirements
- Operation 0
0
C to 40
0
C
For temperature exceeding 40
0
C the power must be reduced
by 1.5% per additional degree. A maximum cooling air
temperature of 45
0
C must not be exceeded.
- Storage up to 55
0
C
6.5
Humidity requirements
- Maximum relative humidity 50% at 40
0
C
- Condensation must be effectively precluded.
6.6
Installation altitude
Max. 1000m above sea level. For any higher altitude, the power
must be reduced accordingly. Please contact your nearest KSB
customer service centre.
6.7
Pollution exposure
The room air may contain dry dust comparable to that normally
encountered in work environments with no extraordinary
machinery - induced dust accumulation. Exposure to unusually
high dust levels, acids, corrosive gases, salts, etc. must be
avoided.
6.8
Checking the voltage
Compare the mains voltage with the name plate data and the
control unit’s circuit diagram.
6.9
Logic / circuit diagrams
For each unit are included in the control cabinet, where they must
remain when not in use. This documentation includes a parts list
for electric components.
When ordering spare parts for electric components, please
always indicate the circuit diagram No.
6.10 Over load relay
For d.o.l. starting the adjusting screw on the motor protection
switch must be set to the rated motor current.
For the setting range, refer to electrical performance data.
Compare these data with the motor rating plate. If there are any
discrepancies, the data stated on the rating plate must be
observed.
6.11 Potential equalization
A terminal is provided on the baseplate for connecting a PE wire.

Commissioning / start-up
7.1
Preparations for commissioning / start-up
Safety Instructions
The water company and the fire department must be informed in
due time prior to commissioning / test run. All health and safety
regulations relevant to commissioning shall be observed.
7.2
Test run
Commissioning should be carried out by specialist KSB staff.
Commissioning of the pressure boosting unit - including test run
- shall only be executed in full compliance with all pertinent.
The unit must not be put in operation without
having been filled with water first; this also
applies to test runs, even for checking the direction of
rotation.
Unions between the pump and the pipeline must always be
retightened. Flanged connections must also be checked for
tight fit.
Set the master switch to ‘‘0’’; unlock all motor protection switches
(if applicable). Provide connection to power supply.
