Relative humidity:
95 %, not condensing.
10. Installation
10.1 Mechanical installation
The controller is only suitable for indoor installation. It must not be
exposed to direct sunlight and must be installed in a dry, well-
ventilated but frost-free room.
The controller must be placed as close to the pump as possible
and within view of the pump set. Ensure sufficient space for
installation and subsequent access to the controller and its
components, and make sure that the device is installed at the
correct height. Make sure there is sufficient air circulation for
cooling.
There are three mounting options:
1. mounting on the pump set
2. mounting on the wall
3. mounting on the floor.
Mounting on the wall or floor
Mount the control cabinet on the wall or floor near the pump set
by means of screws. Drill holes into the wall or floor according to
the drilling template on the back or pedestals of the control
cabinet, and use dowels and screws of adequate size.
Mounting on the pump set
Pump sets delivered by Grundfos have a special retainer for the
control cabinet. Mount the control cabinet in the retainer by
means of suitable screws and nuts.
10.2 Electrical connection
Carry out the electrical connection according to local regulations.
Check that the supply voltage and frequency correspond to the
values stated on the nameplate.
The electrical connection must be made in accordance with the
wiring diagram in the control cabinet.
10.2.1 Compact version
For the Compact version of the fire pump set, the controller is
mounted on the base frame and the electric motor is already
connected.
Procedure
• The connection to the mains supply must be fitted with a fuse
of the correct size, in accordance with local regulations, and
connected to the main switch in the control cabinet. PE must
be connected using the PE terminal block.
• Pressure switch 1 must be connected to terminals 6 and 7 in
the control cabinet, and pressure switch 2 to terminals 8
and 9.
• The additional pressure switch for the "Pump running"
indication is to be connected to terminals 12 and 13.
• If there is a level switch for measuring the filling level in the
priming tank, it must be connected to terminals 10 and 11.
• If status and alarm indications are to be transmitted to a
building management system, terminals 31 to 40 must be used
for this purpose.
10.2.2 Flex version
For the Flex version of the fire pump set, the controller cabinet
designed to be mounted on a wall is delivered separately.
In addition to the electric connections described in
section
10.2.1 Compact version , the electric motor cables in the
controller cabinet must be connected to terminals U1, V1, W1
and U2, V2, W2 of the terminal blocks.
