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
•
Make sure that all safety guards are in place and secure
•
Make sure that you have a clear path of retreat
•
Make sure that the product cannot roll or fall over and injure people or damage property
•
Make sure that the lifting equipment is in good condition
•Use a lifting harness, a safety line, and a breathing device as required

en – Original instructions
7
•Allow all pump system components to cool before handling them
•
Make sure that the product has been thoroughly cleaned
•
Disconnect and lock out power before you service the pump
•Check the explosion risk before you weld or use electric hand tools.
Precautions during work
WARNING:
•
Never work alone
•
Always wear personal protective equipment
•
Always use suitable working tools
•
Always lift the product by its lifting device
•
Stay clear of suspended loads
•
Beware of the risk of a sudden start if the product is used with an automatic level control
•
Beware of the starting jerk, which can be powerful
•
Rinse the components in water after you disassemble the pump
•
Do not exceed the maximum working pressure of the pump
•
Do not open any vent or drain valve or remove any plugs while the system is pressurized
•
Make sure that the pump is isolated from the system and that all pressure is released before
disassembling the pump, removing plugs, or disconnecting the piping
•Never operate the pump without a properly installed coupling guard.
In case of contact with chemical substances or dangerous liquids
Follow these procedures for chemicals or hazardous fluids that have come into contact with your
eyes or your skin:
Condition
Action
Chemicals or hazardous fluids in
eyes
1. Hold your eyelids apart forcibly with your fingers.

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
WARNING:
Improper product use can create dangerous conditions and cause personal injuries and damage
to property
Also refer to the “Quick Startup Guide” and the “Installation, Operation and Maintenance Manual”
of the e-SVE, VME, e-HME and e-SVIE pumps supplied with the product.

4 Installation
4.1 Mechanical installation
Also refer to the “Quick Startup Guide” and the “Installation, Operation and Maintenance Manual”
of the e-SVE, VME, e-HME and e-SVIE pumps supplied with the product.
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 the figure.
•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 check valve on the discharge side
•Always install the pressure sensor on the discharge side, after the check valve.
