3. Intended use
3.1 Pumped liquids
The product is suitable for pumping clean, thin,
non-aggressive, non-toxic and non-explosive liquids
without solid particles or fibres.
4. System sizing
The pump is by default set to not stop until it reaches
its maximum pressure.
5. Mechanical installation
5.1 Installation altitude
The installation altitude is the height above sea level
of the installation site.
• Products installed up to 1000 m above sea level
can be loaded 100 %.
• The motors can be installed up to 3500 m above
sea level.
The motor output power (P2) in relation to the
altitude above sea level is shown in the graph below.
Fig. 1 Derating of motor output (P2) in relation
to altitude above sea level
This product has been evaluated for use
with clean water only.
Only use the product according to the
specifications stated in these installation
and operating instructions.
If the water contains sand, gravel or other
debris, there is a risk of pump blockage
and pump damage.
Please install a filter on the inlet side or
apply a floating strainer to protect the
pump.
The system in which the CME Booster is
incorporated must be designed for the
maximum pump pressure.
WARNING
Electric shock
Death or serious personal injury
- Switch off the power supply before you
start any work on the product.
- Make sure that the power supply cannot
be switched on accidentally.
WARNING
Hot liquid
Death or serious personal injury
- To avoid leakage do not overtighten the
pipe connections.
CAUTION
Sharp element
Minor or moderate personal injury
- Wear personal protective equipment.
CAUTION
Crushing of feet
Minor or moderate personal injury
- Wear safety shoes when moving the
product.
- Use lifting equipment.
CAUTION
Back injury
Minor or moderate personal injury
- Use lifting equipment.
Motors installed more than 1000 m above
sea level must not be fully loaded due to
the low density and consequent low
cooling effect of the air.

6. Electrical connection
Check that the supply voltage and frequency
correspond to the values stated on the nameplate.
6.1 Cable requirements
See section 13.4 Cable requirements for more
information on cable cross-sections and conductor
types.
6.1.1 Motor protection
The pump requires no external motor protection. The
motor incorporates thermal protection against slow
overloading and blocking, TP 211 according to IEC
34-11.
6.1.2 Protection against mains voltage transients
The pump is protected against voltage transients by
built-in varistors between the phases and between
phases and earth.

6.2 Standard functional module, FM 200
6.2.1 Inputs and outputs
The module has these connections:
• two analog inputs
• two digital inputs or one digital input and one
open-collector output
• Grundfos Digital Sensor input and output
• two signal relay outputs
• GENIbus connection.
All inputs and outputs are internally separated from
the mains-conducting parts by reinforced insulation
and galvanically separated from other circuits. All
control terminals are supplied with protective
extra-low voltage (PELV), ensuring protection
against electric shock.
6.2.2 Signal relay 1
LIVE: You can connect supply voltages up to 250
VAC to the output.
PELV: The output is galvanically separated from
other circuits. Therefore, you can connect the supply
voltage or protective extra-low voltage to the output
as desired.
6.2.3 Signal relay 2
PELV: The output is galvanically separated from
other circuits. Therefore, you can connect the supply
voltage or protective extra-low voltage to the output
as desired.
6.2.4 Connection terminals for the mains supply
6.2.5 Connection terminals for inputs and
outputs
