Power and Signal Terminal Configuration ■ After detaching the cover, the Main PCB terminal layout appears as shown in the figure below. ■ After disassembling display parts, there is a terminal block in the Main PCB as shown in the figure below. Holding it with hands and pulling towards ceiling detaches it from the Main PCB. ■ Loosen 5 terminal fixing screws located at top part of detached terminal block CN8 (VIS, +, mA, -, ETH) Connector by turning counter-clockwise using a Θ driver. Connect DC 18~24 V power to +, and - then connect signal cable to mA. Tighten 5 terminal fixing screws clockwise so that terminal does not leave the track then insert Main PCB as the same condition before disassembly. -
