1 Applicant: Electrical Apparatus: KROHNE Ltd. Measuring converter, type MFC400F Description of equipment The measuring converter, type MFC400F is used as part of a mass flow measuring system to determine display the mass flow rate of flammable non-flammable liquids. The equipment consists of the separately certified components, electronic assembly, type MFC400, measuring converter housing, type MH300, cable gl, type LC-MASS-Ex as well as a mounting bracket with remote junction box. The measuring converter, type MFC400F is designed as associated apparatus may be installed in the hazardous area. The permissible range of the ambient temperature depends on the design of the housing as follows: Aluminium converter housing: T amb = 40 C C Stainless steel converter housing: T amb = 40 C C Painted versions: T amb = 40 C C Electrical data: Auxiliary power (non-intrinsically safe) depending on version U N = V DC, +30 % / -10 %, Terminals, PCB power supply (f sht periods -25 %), 12 W X2-A28...A31 (L/L+) internal fuse I N 2 A X2-A23...A26 (N/L-) U m = 253 V X2-A13, A14, A16, A19...A21 (PE) f connection to protective extra low voltage with safe isolation (PELV) U N = 24 V AC/DC, 22 VA/12 W 24 V AC, +10 % / -15 %, 50/60 Hz 24 V DC, +30 % / -25 % internal fuse I N 2 A U m = 253 V f connection to protective extra low voltage with safe isolation (PELV) U N = V AC, +10 % / -15 %, 50/60 Hz, 22 VA internal fuse I N 1.6 A Page 1 of 7

Special conditions f safe use 1. The flow meters of type series OPTIMASS 1400C, 2400C, 3400C, 6400C, 7400C shall be included in the equipotential bonding system of the hazardous area. 2. Opening the enclosure inside the hazardous area is only permissible in a de-energized state with keeping a subsequent waiting time (warning label!) This waiting time is: 35 minutes f temperature class T6 10 minutes f temperature class T5 No waiting time is required f temperature classes T4... T1. 3. Only certified cable gls may be applied as cable entries. Non-used openings shall be sealed by means of certified blind plugs. 4. The connecting cables shall be installed as fixed wiring in such a way that they are sufficiently protected against damage. Page 7 of 7
