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.
Check that the supply voltage and frequency
correspond to the values stated on the nameplate.
5.1 Cable requirements
WARNING
Electric shock
Death or serious personal injury
‐ Comply with local regulations as to
cable cross-sections.
5.1.1 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.
5.1.2 Protection against mains voltage transients
The pump is protected against voltage transients by
built-in varistors between the phases and between
phases and earth.
5.2 Standard functional module, FM 200
5.2.1 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.
5.2.2 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.
5.2.3 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.
