Eaton SEFELEC 5 Series User Manual

User manual SEFELEC 5x Series 30 v1.064.2.1. SAFETY LOOPSThe voltages and currents applied by the measuring devices in the SEFELEC 5x range can bedangerous to the touch. The protection of personnel is the responsibility of the management ofthe site where the measurement device is installed.EATON can only give advice; the respect of the conditions of safety is the responsibility of theuser company’s safety manager.A double safety loop is integrated in the devices; it makes it possible to respect the IEC 61010-2-034 and IN60591 standards, either directly or by the addition of external accessories (emer-gency stop button, safety gate, light signalling, safety cage, etc.).This double loop acts, by electromechanical cut-off of the high voltage generators, as soon asone of the loops is opened. The software responds by an alarm message and by stopping thetest. The test cannot restart unless the loops are closed, and on an order from the operator.The lights on the front panel (and optionally a light column) allow the user to see that the meas-urement device is powered (green), and that it is testing (red).Connection of the safety loopsThe device has a double "safety loop" available at points 1-9 and 2-10 of the rear connectionC5. They must be linked to allow a test to be performed.Note: We recommended fitting in series with these connections dry contacts subject to safetyconditions (door closed, cover lowered, etc.).It is possible to connect a red/green signalling light (SEF-CO160) on terminal C5 to indicatevisibly from a distance the presence or absence of potential on the output terminals of the de-vice.NOTEThe connection of connector C5 can be found in paragraph 20.1.1:Safety Connector C5Reminder of the standard: Parts that are dangerous to the touchThe effects of a current passing through the human body were the subject of work recorded inNF EN 50191 of 20 January 2003, available from the AFNOR. It applies to "the installation andoperation of electronic test equipment of test".It is considered that the human body is similar to a non-inductive resistor close to 2 kΩ.Situation of alternating currentsFor voltages higher than 25 VAC: A current of 3 mA (rms)Situation of direction currentsFor voltages higher than 60 VDC: A current of 12 mAIn any event the discharge energy must not exceed 350 mJNote: A maximum current of 0.7 mA peak, enters the perception range of certain persons, alt-hough it does not present a danger.
