4.1.6 Outdoor installation

The enclosure class of MLE motor is a NEMA 3 rating. If you install the motor outdoors, provide the motor with a suitable cover and open the drain holes to avoid condensation on the electronic components. See fig. 2.

When fitting a cover to the motor, observe the guideline in section 4.1.5 Ensuring motor cooling.

Do not lift the product by the terminal box.

The cover must be sufficiently large to ensure that the motor is

B3 B14 B5

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 humidity, we recommend that you enable the built-in standstill heating function.

Fig. 2 Examples of covers (not supplied by Grundfos)

In order to maintain the UL mark, additional requirements apply to the equipment. See Appendix, page 36.

4.1.7 Drain holes

When the motor is installed in moist surroundings or areas with high humidity, the bottom drain hole must be open. The enclosure class of the motor will then be lower. This helps prevent condensation in the motor as the motor becomes self-venting, and it allows water and humid air to escape.

The motor has a plugged drain hole on the drive side. You can turn the flange 90 ° to both sides or 180 °.

4.2.1 Protection against electric shock, indirect contact

WARNING

Electric shock

- Death or serious personal injury

- Connect the motor to a protective ground and provide protection against indirect contact in accordance with local regulations.

DANGER

Electric shock

- Death or serious personal injury

- Use the recommended fuse size, see10.3.1 Supply

voltage

Single-phase supply voltage

• 1 x 200-240 V - 10 %/+ 10 %, 50/60 Hz, PE. Check that the supply voltage and frequency correspond to the

values stated on the nameplate.

If you want to supply the motor through an IT network, make sure that you have a suitable motor variant. If you are in doubt, contact Grundfos.

The wires in the motor terminal box must be as short as possible. Excepted from this is the separated ground conductor which must be so long that it is the last one to be disconnected in case the cable is inadvertently pulled out of the cable entry.

For maximum backup fuse, see 10.3.1 Supply voltage.

Three-phase supply voltage

• 3 x 440-480 V - 10 %/+ 10 %, 50/60 Hz, PE

• 3 x 200-240 V - 10 %/+ 10 %, 50/60 Hz, PE. Check that the supply voltage and frequency correspond to the

values stated on the nameplate. The wires in the motor terminal box must be as short as possible.

Excepted from this is the separated ground conductor which must be so long that it is the last one to be disconnected in case the cable is inadvertently pulled out of the cable entry.

In order to avoid loose connections, make sure that you have pressed home the terminal block for L1, L2 and L3 in its socket when you connect the supply cable.

For maximum backup fuse, see 10.4.1 Supply voltage.

If you want to supply the motor through an IT network, make sure that you have a suitable motor variant. If you are in doubt, contact Grundfos.

Corner grounding is not allowed for supply voltages above 3 x 480 V, 50/60 Hz.

4.2.4 Additional protection

DANGER

Electric shock

Death or serious personal injury

- Only use residual-current circuit breakers (ELCB, GFCI, RCD) of type B.

The residual-current circuit breaker must be marked with the following symbol:

The total leakage current of all the electrical equipment in the installation must be taken into account. You find the leakage current of the motor in sections 10.3.2 Leakage current and

10.4.2 Leakage current (AC). This product can cause a direct current in the protective ground

conductor.

Overvoltage and undervoltage protection

Overvoltage and undervoltage may occur in case of unstable power supply or a faulty installation. The motor is stopped if the voltage falls outside the permissible voltage range. The motor restarts automatically when the voltage is again within the permissible voltage range. Therefore, no additional protection relay is required.

The motor is protected against transients from the power supply according to EN 61800-3. In areas with high lightning intensity, we recommend external lightning protection.

Overload protection

If the upper load limit is exceeded, the motor automatically compensates for this by reducing the speed and stops if the overload condition persists.

The motor remains stopped for a set period. After this period, the motor automatically attempts to restart. The overload protection prevents damage to the motor. Consequently, no additional motor protection is required.

Overtemperature protection

The electronic unit has a built-in temperature sensor as an additional protection. When the temperature rises above a certain level, the motor automatically compensates for this by reducing the speed and stops if the temperature keeps rising. The motor remains stopped for a set period. After this period, the motor automatically attempts to restart.

Protection against phase unbalance

Three-phase motors must be connected to a power supply with a quality corresponding to IEC 60146-1-1, class C, to ensure correct motor operation at phase unbalance. This also ensures long life of the components.

4.2.5 Connection terminals

The descriptions and terminal overviews in this section apply to both single- and three-phase motors.

For maximum torques, see section, Torques, page 34.

Connection terminals, CREDP pumps

CREDP pumps have a number of inputs and outputs enabling the pumps to be used in advanced applications where many inputs and outputs are required.

The pumps have these connections:

• three analog inputs

• one analog output

• two dedicated digital inputs

• two configurable digital inputs or open-collector outputs

• Grundfos Digital Sensor input and output

• two Pt100/1000 inputs

• two LiqTec sensor inputs

• two signal relay outputs

• GENIbus connection. See fig. 8.

Digital input 1 is factory-set to be start-stop input where open circuit results in stop. A jumper has been factory-fitted between terminals 2 and 6. Remove the jumper if digital input 1 is to be used as external start-stop or any other external function.

DANGER

Electric shock

Death or serious personal injury

- Make sure that the wires to be connected to the connection groups below are separated from each other by reinforced insulation in their entire lengths.

• Inputs and outputs All inputs and outputs are internally separated from the power

supply-conducting parts by reinforced insulation and galvanically separated from other circuits. All control terminals are supplied by protective extra-low voltage (PELV), thus ensuring protection against electric shock.

• Start-stop: (Digital input 1) = Terminals 2 and 6

• Pressure sensor: (Analog input 1) = Terminals 4 and 8

• Pressure switch: (Digital input 3) = Terminals 6 and 10

• External analog signal input: (Analog input 2) = Terminals 7 and 23

• GENIbus Terminals A, Y and B

• Signal relay outputs

– Signal relay 1:

LIVE: You can connect supply voltages up to 250 VAC. 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.

Via a bus signal, it is possible to remote-set motor operating parameters, such as setpoint and operating mode. At the same time, the motor can, via the bus, provide status information about important parameters, such as actual value of control parameter, input power and fault indications.

Contact Grundfos for further information.

If a bus signal is used, the number of settings available via the Grundfos GO Remote will be reduced.

8.6 Priority of settings

The motor can always be set to operation at max. speed or to stop with the Grundfos GO Remote.

If two or more functions are enabled at the same time, the motor will operate according to the function with the highest priority.

Example: If, via the digital input, the motor has been set to max. speed, the motor control panel or the Grundfos GO Remote can only set the motor to "Manual" or "Stop".

The priority of the settings appears from the table below:

Priority Start/stop button

1 Stop 2 Stop* 3 Manual 4 Max. speed* 5 Stop 6 Stop 7 Max. speed 8 Min. speed

9 Start 10 Max. speed 11 Min. speed 12 Min. speed 13 Start 14 Start

* If the bus communication is interrupted, the motor will resume

its previous operating mode, for example "Stop", selected on the motor control panel or with the Grundfos GO Remote.

(50 °C), but continuous operation at higher temperatures reduces the expected product life. If the motor is to operate at ambient temperatures between 122 °F (50 °C) and 140 °F (60 °C), select an oversized motor. Contact Grundfos for further information.

10.1.3 Installation altitude

If the motor is installed above 6560 ft (2000 m), it does not comply with SELV/PELV classification.

Installation altitude is the height above sea level of the installation site.

QR98413121

Motors installed up to 3280 ft (1000 m) above sea level can be loaded 100 %.

• Motors installed more than 3280 ft (1000 m) above sea level must not be fully loaded due to the low density and consequent low cooling effect of the air. See fig. 49.

9.3 Cleaning the product

WARNING

Electric shock

Death or serious personal injury

- Switch off the power supply to the motor and to the signal relays. Check that the terminal box cover is intact before spraying water on the product.

In order to avoid condensation in the motor, let the motor cool down before spraying it with cold water.
