Before Starting Operation In Hazardous Areas; Definition Of Explosion-Proof Protection - FLUX F 550 Allgemeine Originalbetriebsanleitung

> Make sure that the supply voltage corresponds to the voltage indicated on the name
plate.
> When using compressed air motors please do not exceed the maximum operating
pressure of 6 bars and use a filter-regulator-lubricator unit.
> When using compressed air motors, adjust the speed by a ball valve in the air supply
line. Slowly bring the air motor to operating speed.
Do not exceed the maximum speed of 1000 rpm.
The motor (electrical or driven by compressed air) must not exceed 1.5 kW.
> Before inserting the electrical plug into the socket, ensure that the Start/Stop switch is
set to "0" (Stop). On compressed air motors, close the valve in the air supply line.
> Immerse the pump into the liquid and secure it in a vertical position by the use of a com-
pression gland or a container clamp.
> Immerse the hose end into the container to be filled and secure it by an appropriate
device.

Before starting operation in hazardous areas

Note!
Explosion protection at the connection point is not necessary if the
power socket or the terminal box is clearly located outside the hazard-
ous area
In order to transfer flammable fluids class IIA and IIB, temperature class T1 to T4, only
use pumps that are approved for use in category 1 (zone 0).

Definition of explosion-proof protection:

Category 1 (ZONE 0): The external part of the pump between the pump suction end and its
outlet connection.
Category 2 (ZONE 1): The external part of the pump between its outlet and the connection
part to the drive motor as well as the internal part of the pump. (During pumping, the internal
part of the pump will always be filled by the liquid).
38/88 Original operating instructions Eccentric worm drive pump F 550 and Sanitary pump F 560
Before each operation check for external damage and smooth
operation.
When using three-phase motors check direction of rotation of the
motor. In case of portable use, check the conformity of phases at
each socket to guarantee always the same direction of rotation.
(Direction of rotation according to the arrow on the bearing flange).
When using the eccentric screw pump, all additional components
(coupling, drive motor, etc.) attached to the connecting part must
be located outside the container.
Attach the equipotential bonding conductors to the pump, motor and
container before use.
