9 . 1 - Electric installation of the motor or the motor reducer of the pump
Check the agreement between the indications of the motor gauge and the supply voltage.
For the connection of the motor to the electrical supply network, follow the indications of the
manual supplied with the motor.
Follow the assembly diagram of wiring, make sure the wires are adapted to the power consumption
and make sure the contacts are tight.
The motors must be protected by suitable circuit breakers and fuses.
Make sure the earth connections are properly made.
Dry run the pump to make sure that the connections are correct and that the direction of rotation
corresponds well with the suction and the discharge of the installation.
9 . 2 - Ground connection of the pump
A bonding strip lug can be seen on the frames and on the pump housing of ALP type pumps.
9 . 3 - Flexible coupling
The motor or motor reducer must have ATEX characteristics adapted to recognized use (group gas
IIB, class of temperature (T) and must explosion-proof.
10 - ATEX characteristics of the pumping installation
A pumping installation can be composed of materials (motor, reducer, sensors…) from which ATEX
characteristics are different from those of the pump.
In this case, the group will have ATEX characteristics corresponding to characteristics ATEX of the
component with the lowest level of protection.
11 - Pumping vat of retention
At a constant arrival of liquid in a vat of retention in an ATEX zone, the uninterrupted start-up can
generate a classification in zone 0.
The case can only arise when the pump is used in the starting position. It is then imperative that the
suction pipe always has liquid present so as not to create explosive conditions in the presence of
fuel and combustive agents. Thus, the adjustment of the low point of the tank will have to be higher
than the opening of the suction pipe.
That will always result in the presence of liquid and not of gas and liquid.
