1.2.3 General safety rules
WARNING:
Always keep the work area clean.
Pay attention to the risks presented by gas and vapors in the work area.
Always bear in mind the risk of drowning, electrical accidents, and burn injuries.
DANGER: Electrical hazard
Avoid all electric dangers; pay attention to the risk of electric shock or electric arcs
Unintended rotation of motors creates voltage and can charge the unit, resulting in death,
serious injury, or equipment damage. Ensure that motors are blocked to prevent unintended
rotation.
Magnetic fields
The removal or installation of the rotor in the motor casing generates a strong magnetic field.
DANGER: Magnetic hazard
The magnetic field may be dangerous for anyone wearing peacemakers, or any other medical
devices sensitive to magnetic fields.
NOTE
The magnetic field may attract metal debris on the rotor surface, causing damage to the same.
Electrical connections
DANGER: Electrical hazard
The connection to the electric power supply must be completed by an electrician possessing
the technical-professional requirements outlined in the current regulations
Precautions before work
WARNING:
Install a suitable barrier around the working area, for example a guard rail

Sensors
The following sensors can be used with the unit:
 Level-sensor
RS485 Module
For the connection of a multi-pump system to a supervision system, via cable (Modbus or BACnet
MS/TP protocol)
Wireless Module
To connect and interact wireless with e-SM Drive
Adaptor
M20 Metric to 1/2" NPT Adapter (item is always supplied for US market)
3.4 Intended use
The product can be used to pump:
Cold water
Hot water
Refer to the standard Installation, Operation and Maintenance Manual for pump design
specification.
The variable speed pump units are made for the following applications:
Pressure, level, and flow regulation (open loop systems)
Single or multi pump irrigation systems.
3.4.1 Application alternatives
Actuator (constant speed)
The unit operates as an actuator according to speed set point; this is done through user
interface, the corresponding analog input or the communication bus.
Controller (constant pressure)
This mode is set as the default operating mode, and is used for single pump operating units.
Cascade serial / Cascade synchronous
The units are connected via the RS485 interface and communicate via the provided protocol.
The combination of the different units which are used in a multi-pump system depends on the
system requirements.
It is possible to run all pumps in cascade serial mode and cascade synchronous mode as well. If
one unit fails, then each pump of the system can become the lead pump and can take control.
3.5 Improper use
The product must not be used for closed loop systems.

4.1 Mechanical installation
4.1.1 Installation area
DANGER: Potentially explosive atmosphere hazard
The operation of the unit in environments with potentially explosive atmospheres or with
combustible dusts (e.g.: wood dust, flour, sugars and grains) is strictly forbidden.
WARNING:
Always wear personal protective equipment
Always use suitable working tools
When selecting the place of installation and connecting the unit to the hydraulic and electric
power supplies, strictly comply with current regulations.
Ensure that the input protection rating of the unit (IP 55, NEMA Type 1) is suitable for the
installation environment.
CAUTION:
Input protection: to ensure the IP55 (NEMA type 1) protection index make sure that the unit is
closed correctly.
Before opening the terminal box cover, make sure that there is no water in the unit
Make sure that all unused cable glands and cable holes are correctly sealed
Make sure that the plastic cover is correctly closed
Do not leave the terminal box without cover: risk of damage due to contamination.
4.1.2 Unit installation
See the Quick Startup Guide instructions (code 001080128)
Position the unit as shown in Figure 10
Install the unit according to the systems liquid flow.
The arrows on the pump body indicate the flow and the rotation direction
The standard rotation direction is clockwise (looking at the fan cover)
Always install a backflow-prevention device on the suction side.
Always install the pressure sensor on the delivery side, after the check valve.

4.1.3 Outdoor unit installation
In case of outdoor unit installation, ensure appropriate cover (see example in Figure 11).
The size of the cover must be such that the motor is not exposed to snow, rain or direct sunlight;
comply with the guidelines of Par. 9, Table 16.

4.2 Hydraulic installation
Figure 12 and 13 show a single pump system and a multi-pump system respectively.
NOTICE:
If the system is directly connected to the water network, install a minimum pressure switch on the
suction side.

Pressure tank
On the pump delivery side there is a membrane expansion vessel, which gives the possibility of
maintaining the pressure inside the piping when the system is not being used. The unit stops the
pump from continuing to run at zero demand and reduce the size of the tank that is required for
supply purposes.
Select a vessel suitable for the system pressure, and pre-load it in accordance with the values

4.3 Electrical Installation
DANGER: Electrical hazard
The connection to the electric power supply must be completed by an electrician possessing the
technical-professional requirements outlined in the current regulations.
4.3.1 Electrical requirements
Local directives prevail on the specific requirements indicated below.
Electrical connection checklist
Check that the following requirements are met:
The electrical leads are protected from high temperature, vibrations, and collisions.
The current type and voltage of mains connection must correspond to the specifications on
the data plate on the pump.
The power supply line is provided with:
- A high-sensitivity differential switch (30 mA) [residual current device RCD] suitable for
earth fault currents with DC or pulsating DC content (a Type B RCD is suggested).
- A mains isolator switch with a contact gap of at least 3 mm.
The electrical control panel checklist
NOTICE:
The control panel must match the ratings of the electric pump. Inappropriate combinations do not
guarantee the protection of the unit.
Check that the following requirements are met:
The control panel must protect the pump against short-circuit. A time lag fuse or a circuit
breaker (Type C model is suggested) can be used to protect the pump.
The pump has built in overload and thermal protection, no additional overload protection is
required.
DANGER: Electrical hazard
Before starting work on the unit, make sure that the unit and the control panel are isolated from
the power supply and cannot be energized.
Grounding (earthing)
DANGER: Electrical hazard
Always connect the external protection conductor to the ground terminal before attempting to
make any other electrical connections
Connect all the electric accessories of the pump and the motor to the ground, making sure that
the connections are completed correctly
Check that the protection conductor (ground) is longer than the phase conductors; in case of
accidental disconnection of the power supply conductor, the protection conductor (ground)
must be the last one to detach itself from the terminal.
Use a cable with several strands to reduce electric noise.
