MD2 Modem (07/2002) 5-23

Wiring Adaptation for the Multiple Transformer

When the MD2 modem is connected to a multiple transformer using cable

6NH7700-2AR60 the wiring needs to be adapted. To do this cut the Western

connector at the multiple transformer's end and solder the wires directly on the

multiple transformer. The following table shows the wiring configuration for the

connection to the multiple transformer.
