2) ∑I1 plus I2 shall comply with the limits in Table 5A (see 5.1.6). 3) If relevant, such equipment shall comply with 5.1.7. The value ofI 2 shall be used to calculate the 5 % input current limit per phase specified in 5.1.7. Compliance with item a) is checked by inspection and, if necessary, by test. If the equipment has provision for a permanent protective earth connection in accordance with item 1) above, it is not necessary to make any measurements, except that I2 shall comply with the relevant requirements of 5.1.TOUCH CURRENT tests, if necessary, are made using the relevant measuring instrument described in Annex D or any other instrument giving the same results. A capacitively coupled a.c. source of the same line frequency and phase as theAC MAINS SUPPLY is applied to each telecommunication port such that 0,25 mA, or the actual current from other equipment if known to be lower, is available to flow into that telecommunication port. The current flowing in the earthing conductor is then measured. b) EUT whose telecommunication ports have no reference to protective earth If the telecommunication ports on the EUT do not have a common connection, each telecommunication port shall comply with 5.1.8.1.If all telecommunication ports or any groups of such ports have a common connection, the total TOUCH CURRENT from each common connection shall not exceed 3,5 mA. Compliance with item b) is checked by inspection and, if necessary, by the tests of 5.1.8.1 or, if there are common connection points, by the following test. A capacitively coupled a.c. source of the same frequency and phase as the AC MAINS SUPPLY is applied to each telecommunication port such that 0,25 mA, or the actual current from the other equipment if known to be lower, is available to flow into that telecommunication port. Common connection points are tested in accordance with 5.1, whether or not the points are accessible.
