Make sure that the electrical installation supports the rated current [A] of the product. See the product's nameplate.
DANGER
Electric shock
Death or serious personal injury
‐
Make sure that the product is connected only to a properly grounded, grounding-type receptacle (protective earthing).
‐
The protective earth of the power outlet must be connected to the protective earth of the product. The plug must therefore have
the same PE connection system as the power outlet. If not, use a suitable adapter.
1.
Switch off the power supply to the power socket.
2.
Connect each plug to its own power socket.
4.3.7 Connecting a fuse box to the electrical installation
Relevant for products delivered without a power plug. This product variant is supplied with a 5 m cable and a fuse box.
All electrical connections must be carried out by a qualified electrician in accordance with local regulations.
DANGER
Electric shock
Death or serious personal injury
‐
Switch off the power supply to the product including the power supply for the signal relays. Wait at least 5 minutes before you
make any connections in the terminal box.
‐
Make sure that the power supply cannot be switched on accidentally.
1.
Switch off the power supply.
2.
Open the fuse box and find the wiring diagram.
3.
Mount the fuse box on a wall or the like, so connection to the electrical installation can be performed safely.
4.
Connect the cables from the electrical installation and from the pump to the fuse box according to the wiring diagram.
5.
Close the fuse box, and switch on the power.
4.4 Wiring diagram
4.4.1 Standard functional module, FM 200
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.
The 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.
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.
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.
