(For more information on the limitationabout the use of digital phone phones in accordance with the use of PLIM2 port,contact your dealer.) For the use of an external rectifier: The shunt pins (J2, J3 and J4) are connectedbetween pin2 and pin3. There is no restriction on the use of an external rectifierbecause each of them can supply the current of 10 A. Limit each current runningthrough PLIM2 ports below 0.1 A and in the module below 1.6 A.Each jumper is numbered in ascending order from the marked ‘1’ in the following figure.Figure 3.16 Setting the jumpers of PLIM2
