1. 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 d 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 e 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 f 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 g The installation use and maintenance of isolate barrier should strictly abide by the relevant contents of GB3836 15 2000 Part 15 of Explosive Gas Electrical Equipment Dangerous place electrical installation except mine GB50058 1992 Electrical Equipment design code of Explosion and Fire Risk Environment and product brochures 8 Package and Storage 8 1 Isolate barriers should be packed with transparent plastic bags and put in the special packing boxes 8 2 Isolate barriers should be stored in a ventilation indoor environment with ambient temperature of 5 40 C and relative2.
