4. Electrical connection

DANGER
Electric shock
Death or serious personal injury
‐
In case of an insulation fault, the fault current may be
a DC or pulsating DC.Observe national legislation
about requirements for and selection of Residual
Current Device (RCD) when installing the product.
WARNING
Electric shock
Death or serious personal injury
‐
Carry out the electrical connection in accordance with
local regulations.
WARNING
Electric shock
Death or serious personal injury
‐
Check that the power plug delivered with the product
is in compliance with local regulations.
‐
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 if allowed by local regulations.
‐
Provide protection against indirect contact in
accordance with local regulations.
‐
Make sure all earth connections are established
correctly before switching on the power supply.
‐
The user or the installer is responsible for correct
earthing and protection according to local regulations.
‐
The installer is responsible for potential compensation.
‐
Work must be carried out according to IEC
60204-1:2016.
WARNING
Electric shock
Death or serious personal injury
‐
Power cables without a plug must be connected to a
supply disconnecting device incorporated in the fixed
wiring according to local regulations.
WARNING
Electric shock
Death or serious personal injury
‐
A supply disconnecting device made according to EN
60204-1 5.3.2 must be provided with means permitting
it to be locked in the OFF (isolated) position. This
device must also be installed in a position according to
EN 60204-1, 5.3.4.
Check that the supply voltage and frequency correspond to the
values stated on the nameplate.

4.1 Cable requirements

WARNING
Electric shock
Death or serious personal injury
‐
Comply with local regulations as to cable cross-
sections.
4.1.1 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.
4.1.2 Protection against mains voltage transients
The pump is protected against voltage transients by built-in
varistors between the phases and between phases and earth.

4.2 Standard functional module, FM 200

4.2.1 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.
4.2.2 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.
4.2.3 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.
