Compliance is checked by inspection and measurement. 5.1.7.2 Simultaneous multiple connections to the supply The following applies to EUT tested in accordance with 5.1.2.3. If the result of the total TOUCH CURRENT measurement exceeds 3,5 mA r.m.s., the test is repeated with eachAC MAINS SUPPLY and its PROTECTIVE EARTHING CONDUCTOR connected one at a time, with the otherAC MAINS SUPPLIES, including their PROTECTIVE EARTHING CONDUCTORS, disconnected. However, if two connections to theAC MAINS SUPPLY are inseparable, for example, connections for a motor and its control circuits, they shall both be energized for a repeat test. NOTE It is not expected that the EUT will operate normally during this test. If the result of the TOUCH CURRENT measurement for any of the repeat tests exceeds 3,5 mA r.m.s., the requirements of 5.1.7.1 a) apply to that connection to theAC MAINS SUPPLY. For calculating 5 % of the input current per line, the input current from the AC MAINS SUPPLY , measured during the repeat test, is used.5.1.8 Touch currents to telecommunication networks and cable distribution systems and from telecommunication networks NOTE In this subclause, references to "TELECOMMUNICATION NETWORK connection ports" (or telecommunication ports) are intended to cover those connection points to which a TELECOMMUNICATION NETWORK is intended to be attached. Such references are not intended to include other data ports, such as those commonly identified as serial, parallel, keyboard, game, joystick, etc.5.1.8.1 Limitation of the touch current to a telecommunication network or to a cable distribution system The TOUCH CURRENT from equipment supplied from the AC MAINS SUPPLY to a TELECOMMUNICATION NETWORK or a CABLE DISTRIBUTION SYSTEMshall be limited. Compliance is checked using the test circuit detailed in 5.1.3.The tests are not applied to equipment where the circuit to be connected to a TELECOMMUNICATION NETWORK or aCABLE DISTRIBUTION SYSTEMis connected to a protective earthing terminal in the equipment; the TOUCH CURRENT from the EUT to the TELECOMMUNICATION NETWORK or the CABLE DISTRIBUTION SYSTEM is considered to be zero.
