CDM-Qx/QxL AC Modem Installation: The installation and connection to the line supply must
be made in compliance to local or national wiring codes and regulations. The CDM-Qx/QxL is
designed for connection to a power system that has separate ground, line and neutral conductors.
The equipment is not designed for connection to a power system that has no direct connection to
ground.
CDM-Qx/QxL DC Modem Installation: The CDM-Qx/QxL DC input is connected to a nominal
48 VDC prime power source. The DC input is isolated from the chassis and from the DC output to
the BUC if equipped with internal BUC power supply. The chassis may be connected to a local
system ground using a separate wire to the ground stud on the back of the chassis. Since the DC
input is isolated, either the positive or the negative side of the DC input may be common with local
ground. Labeling on the chassis rear panel indicates the positive and negative terminals of the input
power socket.
Telecommunications Terminal Equipment Directive
In accordance with the Telecommunications Terminal Equipment Directive 91/263/EEC, this
equipment should not be directly connected to the Public Telecommunications Network.
