1.2 Problem solution
Solution in the factory
The s olution of the problem is to replace the cable sockets of the ma ins input.
The good cable sockets can be distinguished from the bad ones by their c olor:
• transparent blue, showing the print AMP: these are the good cables sockets
• full blue, showing the print Panduit: these cable sockets can cause the problem

Solution in the field
It is possible to adjust the Panduit cable sockets with a pair of pliers: pinch the cable socket
so that the s lot in which the male plug slides, becomes more narrow (dimension x on im-
age 1-4). This will insure good contact between the female cable socket and the male plug.
