7 Installation and electrical connection

DANGER! Risk of electric shock!
Personnel dedicated to the connection of elec-
trical equipment and motors must be skilled for 
such work. They shall make the connection 
according to the wiring diagrams supplied, in 
accordance with regulations and laws in force. In 
addition, they must ensure that they have shut-
down power before performing any operation 
which provides the possible contact with the 
electrical parts . Check earth continuity.

7.1 Installation

Install the booster in an easily accessible room, 
ventilated and protected from rain and frost. 
To make sure that the booster can pass through 
the room door.
For maintenance works, a sufficient place must be 
provided. The unit must be easily accessible.
Installation place has to be horizontal and flat. It 
must be robust enough to support the system 
weight.
The room must be exclusively dedicated to fire 
equipment, directly accessible from the outside, 
and having a fire resistance of at least 60 minutes 
(see standards).
The room must be, in order of preference:

• separate from the protected building (isolated)
• closed to the protected building 
• Inside the protected building.

NOTE:
For rooms with closed walls or inside the building, 
it is preferable to have a fire resistance superior to 
120 minutes. The temperature inside the room 
must not be less than 10

°C

 (4

°C

 in the presence 

of electric pumps) or more than 25

°C

 (40

°C

 in the 

presence of electric pumps).
The room shall be equipped with openings to the 
outside to ensure adequate ventilation for cooling 
engines (electric and diesel) and for diesel engine 
combustion.
The room also shall be equipped with a sprinkler-
type protection (EN 12845).
Sprinkler protection can be directly supplied by 
the discharge manifold of the booster, as required 
by the EN 12845 standard. 
Access to the room must be guaranteed and easy 
for people, even if the installation of fire is on, 
without light, if there is snow or rain, and in any 
case that can affect access negatively. Access to 
the room must be sufficiently reported and admit-
ted only to authorised, specialised and properly 
trained personnel.

Avoid access to the system for unauthorised 
persons!
The booster is a fire equipment using AUTO-
MATIC START and MANUAL STOP ONLY. For this 
reason, there must have a clearly visible sign in 
the system room warning that this logic opera-
tion makes the possibility of an unexpected auto 
start.
The pump unit is NOT equipped with emergency 
stop. The main pumps can only be manually 
stopped (see corresponding manual of control 
box).
For this reason, before an intervention on group 
of pumps, make sure you switch off power sup-
ply and avoid any start of pumps.
If possible, pumps must be installed under the 
charge of water. They are considered as such if 
at least two thirds of the actual capacity of the 
suction tank is above the level of the axis of the 
pump and the minimum useful level of the water 
in the tank is not more than two meters below 
the axis of the pump.
If the conditions mentioned above are not 
respected, the booster is considered on suction 
conditions, which are accepted after installation 
of special devices, explicitly described by the 
standard (priming tanks, separated pipes suc-
tion, etc).

7.2 Safety recommendations

WARNING! Risk of Cut!
Do not remove the protection on any rotating 
parts, belts, hot surfaces etc. Never leave tools 
or disassembled parts of the booster on it or 
around it.

DANGER! Risk of fatal injury!
Do not remove the protection of live parts. Pre-
vent each possibility for operate any element 
that isolates the installation or subassemblies 
on which to work. 
Take all precautions to avoid a risk of electrocu-
tion. Control earth connection, presence and 
continuity, and if a device for protection against 
indirect contact is installed (differential switch). 
If necessary, make operation on the unit by 
using required equipment (insulating gloves, 
isolating base plate).
Never leave the electrical panel or the terminal 
box of electrical motor powers opened. Check if 
there is no possibility of contact with live parts. 
Check if electrical connections and auxiliary 
power are correctly connected. Check the label 
data of electrical panels, in particular tension 
and availability of an adapted power supply.

WARNING! Risk of fire or flash fire!
The charging diesel pump batteries may produce 
potentially explosive gas; avoid flames and 
sparkles. 
Never leave flammable liquids or rags dipped in 
acid around the booster or electrical equip-
ments.
