4. s The circuit wiring of intrinsic ends blue and non intrinsic ends yellow of the isolate barrier is prohibited from wrong and confusion The intrinsic safe leads should use the blue as the marking intrinsic leads and non intrinsic leads should be installed separately in the leads slot and use different casing tubes The intrinsic safety side of isolate barrier is not allowed to have a mixture of other power including other power supply with intrinsic safety current When the isolate barriers are with concentrated layout it should make the intrinsic side adjacent with the intrinsic side and non intrinsic side adjacent with the non intrinsic side to avoid the confusion On the separate power supply debugging of isolate barrier it is important to pay attention to the model power polarity voltage grading and connector tab on the shell of isolate barriers It is forbidden to test the insulation between the terminals of isolate barrier with insulation ohmmeter to check the insulation of the system lines it should disconnect all isolate barriers at first otherwise it would cause the fuse of internal instant fuse If the internal module of isolate barrier is damaged and needs replacement it is needed to return to the factory for repairing The repaired isolate barriers should have a comprehensive re examination before being put into operation The installation use and maintenance of isolate barrier should strictly abide by the relevant conte
