Before Commissioning In Potentially Explosive Atmospheres - FLUX F 570 Originalbetriebsanleitung

Commissioning
 Installation work at electric motors may only be carried out by qualified electricians.
 Observe the maximum operating pressure and operating temperature.
 The screw connections between the progressive cavity pump and the motor must be
securely tightened.
 At the F 580, correct fitting of the claw coupling must be checked (see applicable docu-
ments Assembly sheet - Coupling on motor).
 The power supply must be equipped with a residual-current circuit breaker.

7.2.1 Before commissioning in potentially explosive atmospheres

NOTICE
If the socket outlet or terminal box is clearly located outside the potentially explosive atmosphere,
explosion protection at the connection point can be dispensed with.
 When pumping flammable media of explosion groups IIA and IIB and temperature clas-
ses T1 to T4, only progressive cavity pumps approved for use in category 1 (ZONE 0)
may be used.
 Before each commissioning, check for external damage and for ease of movement.
 When using asynchronous motors, check the direction of rotation of the motor.
 In case of stationary use, check the direction of rotation again.
 When using the progressive cavity pump, all additional components attached to the
connection part (coupling, motor, etc.) must be outside the tank.
 Before use, attach the equipotential bonding conductors to the progressive cavity
pump, motor and container.
 Have the coupling and the carrier checked regularly and inspected for wear by qualified
personnel.
 When using the pumps and motors in potentially explosive atmospheres, do not use
motor adapters.
 No dry running.

tion opening and the discharge connection.
The outer part of the progressive cavity pump between the dis-
charge connection and the connection part for a motor and the in-
ner part of the progressive cavity pump.
When pumping is carried out as intended, the inner part is im-
mersed in the pumped medium.
