4. General information
These installation and operating instructions apply to the
Grundfos TPE pumps.
The pumps are fitted with frequency-controlled
permanent-magnet motors for single-phase or three-phase mains
connection.
4.1 Radio communication
For installation in the USA and Canada, see also page 33.
This product can communicate with the Grundfos GO Remote
and other products of the same type via the built-in radio module.
In some cases, an external antenna may be required.
Only Grundfos-approved external antennas may be connected to
this product, and only by a Grundfos-approved installer.
4.2 Battery
Pumps fitted with the advanced functional module (FM 300)
incorporate a Li-ion battery. The Li-ion battery complies with the
Battery Directive (2006/66/EC). The battery does not contain
mercury, lead and cadmium.
5. Mechanical installation
5.1 Mounting
The pump must be secured to a solid foundation by bolts through
the holes in the flange or the base plate.
5.2 Cable entries
The motor has four M20 screwed cable entries fitted with blind
plugs from factory.
The following cable glands are included:
• 2 x M20 cable gland, cable diameter ∅0.016" (5 mm)
• 1 x M20 cable gland, cable diameter ∅0.023 -0.046"
(7-14 mm).
5.3 Ensuring motor cooling
Fig. 1 Minimum distance (D) from the motor to a wall or other
fixed objects
5.4 Outdoor installation
When installed outdoors, the motor must be provided with a
suitable cover to avoid condensation on the electronic
components. See fig. 2.
The cover must be sufficiently large to ensure that the motor is
not exposed to direct sunlight, rain or snow. Grundfos does not
supply covers. We therefore recommend that you have a cover
built for the specific application. In areas with high air humidity,
we recommend that you enable the built-in standstill heating
function.
Fig. 2 Examples of covers (not supplied by Grundfos)
5.5 Drain holes
When the motor is installed in moist surroundings or areas with
high air humidity, the bottom drain hole should be open.
The enclosure class of the motor will then be lower. The open
drain hole helps prevent condensation in the motor as it will make
the motor self-venting and allow water and humid air to escape.
The motor has a plugged drain hole on the drive side. The flange
can be turned 90 ° to both sides or 180 °.
Fig. 3 Drain holes
Warning
Installation and operation must comply with local
regulations and accepted codes of good practice.
Note
Note
In order to maintain the UL mark, additional
installation procedures must be followed.
See page 33.
Note
Note
In order to ensure sufficient cooling of the motor,
the distance (D) between the end of the fan cover
and a wall or other fixed objects must always be
at least 0.16" (50 mm), irrespective of motor size.
See fig. 1.

6.5 Signal cables
• Use screened cables with a cross-sectional area of min.
AWG 20 (0.5 mm2) and max. AWG 16 (1.5 mm2) for external
on/off switch, digital inputs, setpoint and sensor signals.
• Connect the screens of the cables to frame at both ends with
good connection. The screens must be as close as possible to
the terminals. See fig. 10.
Fig. 10 Stripped cable with screen and wire connections
• Screws for frame connections must always be tightened
whether a cable is fitted or not.
• The wires in the motor terminal box must be as short as
possible.
6.6 Bus connection cable
6.6.1 New installations
For the bus connection, use a screened 3-core cable with a
cross-sectional area of min. AWG 20 (0.5 mm2) and max.
AWG 16 (1.5 mm2).
• If the motor is connected to a unit with a cable clamp which is
identical to the one on the motor, connect the screen to this
cable clamp.
• If the unit has no cable clamp as shown in fig. 11, leave the
screen unconnected at this end.
Fig. 11 Connection with screened 3-core cable
6.6.2 Replacing an existing motor

7. Operating conditions
7.1 Maximum number of starts and stops
The number of starts and stops via the power supply must not
exceed four times per hour.
When switched on via the power supply, the pump will start after
approx. 5 seconds.
If a higher number of starts and stops is desired, use the input for
external start/stop when starting/stopping the pump.
When started via an external on/off switch, the pump will start
immediately.
7.2 Ambient temperature
7.2.1 Ambient temperature during storage and transportation
-22 - +140 °F (-30 - +60 °C).
7.2.2 Ambient temperature during operation
-4 - +122 °F (-20 - +50 °C).
The motor can operate with the rated power output (P2) at 122 °F
(50 °C), but continuous operation at higher temperatures will
reduce the expected product life. If the motor is to operate at
ambient temperatures between 122 and 140 °F (50 and 60 °C),
an oversized motor must be selected. Contact Grundfos for
further information.

5. Mechanical installation.
7.5 Motor cooling
To ensure cooling of motor and electronics, observe the following:
• Position the motor in such a way that adequate cooling is
ensured. See section 5.3 Ensuring motor cooling.
• The temperature of the cooling air must not exceed 122 °F
(50 °C).
• Keep cooling fins and fan blades clean.
8. User interfaces
Pump settings can be made by means of the following user
interfaces:
• Standard control panel.
See section 9. Standard control panel.
• Grundfos GO Remote.
See section 10. Grundfos GO Remote.
If the power supply to the pump is switched off, the settings will
be stored.
Factory settings
The pumps have been factory-set to constant-curve control
mode. See section 9.1.2 Pump in constant-curve control mode.

9.1 Setpoint setting
Set the desired setpoint of the pump by pressing or .
The light fields on the control panel will indicate the setpoint set.
9.1.1 Pump in differential-pressure control mode
The following example applies to a pump in an application where
a pressure sensor gives a feedback to the pump. If the sensor is
retrofitted to the pump, it must be set up manually as the pump
does not automatically register a connected sensor.
Figure 15 shows that the light fields 5 and 6 are activated,
indicating a desired setpoint of 4.3 psi (3 m) with a sensor
measuring range from 0 to 8.5 psi (0 to 6 m) The setting range is
equal to the sensor measuring range.

11.7 Digital inputs
Available inputs depending on the functional module fitted in the
pump:
To set up a digital input, make the settings below.
Function
Select one of these functions:
•Not active
When set to "Not active", the input has no function.
•External stop
When the input is deactivated (open circuit), the pump will
stop.
•Min. (min. speed)
When the input is activated, the pump will run at the set min.
speed.
•Max. (max. speed)
When the input is activated, the pump will run at the set max.
speed.
•External fault
When the input is activated, a timer will be started. If the input
is activated for more than 5 seconds, the pump will be stopped
and a fault will be indicated.
•Alarm resetting
When the input is activated, a possible fault indication will be
reset.
•Dry running
When this function has been selected, lack of inlet pressure or
water shortage can be detected.
When lack of inlet pressure or water shortage (dry running) is
detected, the pump will be stopped. The pump cannot restart
as long as the input is activated.
This requires the use of an accessory, such as these:
– a pressure switch installed on the suction side of the pump
– a float switch installed on the suction side of the pump.
•Accumulated flow
When this function has been selected, the accumulated flow
can be registered. This requires the use of a flowmeter which
can give a feedback signal as a pulse per defined flow of
water.
See section 11.15.1
Pulse flowmeter setup .
•Predefined setpoint digit 1 (applies only to digital input 2).
When digital inputs are set to predefined setpoint, the pump
will operate according to a setpoint based on the combination
of the activated digital inputs.
See section 11.13.2
Predefined setpoints .
The priority of the selected functions in relation to each other
appears from section 16. Priority of settings. A stop command will
always have the highest priority.

signalling. See section 18. Signal relays for further information.
The signal relays can be configured to be activated by one of the
following incidents:
•Ready
•Operation
•Alarm
•Warning
•Limit 1 exceeded
•Limit 2 exceeded
•Pump running
•Control of external fan
•Not active.
11.10 Analog output
Whether the analog output is available or not, depends on the
functional module fitted in the pump:
To set up the analog output, make the settings below.
Output signal
•0-10 V
•0-20 mA
•4-20 mA.
Function of analog output
•Actual speed
•Actual value
•Resulting setpoint
•Motor load
•Motor current
•Limit 1 exceeded
•Limit 2 exceeded
•Flow rate.
11.11 Controller settings
The pumps have a factory default setting of gain (Kp) and integral
time (Ti).
However, if the factory setting is not the optimum setting, the gain
and the integral time can be changed:
• Set the gain (Kp) within the range from 0.1 to 20.
• Set the integral-action time (Ti) within the range from 0.1 to
3600 s.
If 3600 s is selected, the controller will function as a P
controller.
Furthermore, the controller can be set to inverse control.
This means that if the setpoint is increased, the speed will be
reduced. In the case of inverse control, the gain (Kp) must be set
within the range from -0.1 to -20.
Guidelines for setting of PI controller
The tables below show the recommended controller settings:
L1 = Distance ft (m) between pump and sensor.
1) In heating systems, an increase in pump performance will
result in a rise in temperature at the sensor.
2) In cooling systems, an increase in pump performance will
result in a drop in temperature at the sensor.
L2 = Distance ft (m) between heat exchanger and sensor.
