Mechanical installation

4.1.1

Installation area

Also refer to the "Quick Startup Guide" and the
"Additional Installation, Operation and Maintenance
Instructions" of e-LNEE, e-LNES, e-LNTE and e-LNTS
pumps.
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 ingress protection rating of
the unit (IP 55, type 1) is suitable for the
installation environment.
CAUTION:
• Input protection: to ensure the IP55 (type
1) protection index make sure that the unit
is closed correctly.
• Before opening the terminal box cover,
check that there is no liquid 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
001080130)
• Position the unit as shown in Figure 4
• Install the unit according to the systems liquid flow.
• The arrows on the pump body indicate the flow and
the rotation direction
• In case of operation with pressure sensors, these
must be installed instead of the plugs found on the
suction and discharge flange.
• Always install a check valve on the discharge side.
• Always install the pressure sensor on the discharge
side, after the check valve.
4.1.3

Outdoor unit installation

In case of outdoor unit installation, ensure appropriate
cover (see example in Figure 5). 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
Table 3.
4.2

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.
4.2.1

Electrical requirements

Local directives prevail on the specific requirements
indicated below.
Electrical connection check list
Check that the following requirements are met:
• The electrical leads are protected from high
temperature, vibrations, and collisions.
• The main power supply current and voltage must
meet the specifications on the data plate on the unit
• The power supply line is provided with:
- A mains isolator switch with a contact gap
of at least 3 mm.
• Ground fault circuit breaker (GFCI), or residual
current devices (RCD), also known as automatic
earth leakage circuit breakers (ELCD); comply with
the following:
- For single-phase power supply versions
use GFCI (RCD), which are capable of
detecting alternate currents (AC) and
pulsing currents with DC components.
These GFCI (RCD) are marked with the
following symbol
- For three-phase power supply versions
use GFCI (RCD), which are capable of
detecting AC and DC currents. These
GFCI (RCD) are marked with the following
symbols
- Use GFCI (RCD) with a starting delay, to
avoid problems due to transient earth
currents.
- The size of the GFCI (RCD) must comply
with the system configuration and the
environmental conditions.
NOTICE:
When selecting an automatic earth leakage
circuit breaker or a ground fault circuit
breaker, make sure to consider the total earth
leakage current of all the electric devices of
the system.
