Connect 1x 115 V models into a 1 x 115 V outlet
We recommend connecting 1 x 115 V models
directly into a 1 x 115 V outlet. If an extension
cord is used, do not use wire smaller than 14
AWG.
Use of metal conduit with metal conduit
connectors is recommended for all electrical
connections.
6.2.2 Single-phase motors
If the motor is connected to an electric installation
where an earth leakage circuit breaker (ELCB) or
ground fault circuit interrupter (GFCI) is used as
additional protection, this circuit breaker or
interrupter must be marked with the following
symbol:
When an earth leakage circuit breaker or ground
fault circuit interrupter is selected, the total
leakage current of all the electrical equipment in
the installation must be taken into account.

6.3 Wiring diagram
6.3.1 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.
