GB 6Guidance and manufacturer’s declaration – electromagnetic immunityThe AC-110MD is intended for use in the electromagnetic environment specified below. The customer or the user of theAC-110MD should assure that it is used in such an environment.Immunity test IEC 60601test level Compliance level Electromagnetic environment – guidancePortable and mobile RF communications equipmentshould be used no closer to any part of the AC-110MD,including cables, than the recommended separationdistance calculated from the equation appliance to thefrequency of the transmitter.Recommended separation distanceConducted RFIEC 61000-4-63 Vrms150 kHz to 80 MHzoutside ISM bands c3 Vrms d = 1.2 √P6 Vrms150 kHz to 80 MHzin ISM bands c6 VrmsRadiated RF 3 V/m 3 V/m IEC 60601-1-2: 2007d = 1.2 √P 80 MHz to 800 MHzd = 2.3 √P 800 MHz to 2.5 GHzIEC 60601-1-2: 2014d = 2.0 √P 80 MHz to 2.7 GHzWhere P is the maximum output power rating of thetransmitter in watts (W) according to the transmittermanufacturer and d is the recommended separationdistance in meters (m).Field strengths from fixed RF transmitters, asdetermined by an electromagnetic site survey, a shouldbe less than the compliance level in each frequencyrange. bInterference may occur in the vicinity of equipmentmarked with following symbol:IEC 61000-4-3 80 MHz to 2.7 GHzNOTE 1: At 80 MHz and 800 MHz, the higher frequency range applies.NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption andreflection from structures, objects and people.
