4.1 Precautions
General precautions
Before starting, make sure that the safety instructions shown in Introduction and Safety on
page 4 have been fully read and understood.
DANGER:
All the hydraulic and electrical connections must be completed by a technician possessing the
technical
-professional requirements outlined in the current regulations.
WARNING:
Always wear personal protective equipment.
WARNING:
Always use suitable working tools.
WARNING:
Piping must be sized to ensure safety at the maximum operating pressure.
WARNING:
Install appropriate gaskets between the unit and the piping
system.
Electrical measures
DANGER: Electrical hazard
Before starting work, check that the electric power supply is disconnected and locked out, to
avoid unintentional restart of the unit, the control panel and the auxiliary control circuit.
WARNING: Injuries hazard
The unit, equipped with a single
-phase motor with automatic reset thermal overload
protection, could restart inadvertently after it has cooled down: risk of physical injury.
WARNING:
The use of units with single
-phase motors with automatic reset thermal protection for
extinguishing fires and in pulverised water firefighting systems is forbidden.
NOTE:
If using a single
-phase motor other than the standard motor, check that a thermal protection
device has been installed.
NOTE:
Only use dynamically balanced motors with half
-sized key at the shaft end (IEC 60034-14), and
with normal vibration rate (N).

en – Original Instructions
e-SVI series – Additional Installation, Operation and Maintenance Instructions 17
NOTE:
Only use single
-phase or three-phase motors with sizes and powers in compliance with
European standards.
NOTE:
The mains voltage and frequency must match the specifications on the data plates.
Ground
DANGER: Electrical hazard
Always connect the external protection conductor (ground) to the ground terminal before
attempting to make any other electrical connections.
DANGER: Electrical hazard
Connect all the electrical accessories of the unit to the ground.
DANGER: Electrical hazard
Check that the external protection conductor (ground) is longer than the phase conductors. In
case of accidental disconnection of
the unit from the phase conductors, the protection
conductor must be the last one to detach itself from the terminal.
DANGER: Electrical hazard
Install suitable systems for protection against indirect contact, in order to prevent lethal electric
shocks.
