(a) at 50/60 Hz
(b) at 1500 rpm
(c) running smoothly only at motor speeds higher than 200 rpm
(d) The pump is designed for operation with safe extra low voltage. Accordingly only safe extra
low voltage (SELV) may be connected to the voltage supply connections.
(e) In case of supply voltage below 100V, the lock of the cutout might be restricted.
(f) Pumps with voltage changeover switch: IP 40
(g) Measurement according to EN ISO 2151:2004 and EN ISO 3744:1995 at 230V/50Hz or
1500rpm (MD 1C VARIO-SP) and at ultimate vacuum with exhaust tube at outlet
