consumption of 300 watts.
The installation and connection to the line supply must be made in compliance to local or national
wiring codes and regulations.
The CDM-425 Advanced Satellite Modem is shipped with a line inlet cable suitable for use in the
country of operation. If it is necessary to replace this cable, ensure the replacement has an
equivalent specification.
Examples of acceptable ratings for the cable include HAR, BASEC and HOXXX-X.
Examples of acceptable connector ratings include VDE, NF-USE, UL, CSA, OVE, CEBEC,

Fuses

CAUTION – FOR CONTINUED OPERATOR SAFETY, ALWAYS REPLACE THE FUSES WITH THE
CORRECT TYPE AND RATING.
The CDM-425 Advanced Satellite Modem is fitted with two fuses:
•
For AC operation, the unit requires two common 4 Amp/250 volts 20mm x 5mm Slow-blow
fuses that are contained within a fuse holder that is press-fit into the body of the IEC power
inlet module (on the rear panel of the unit).
•
For DC operation, the unit requires two different fuses that are contained within the individual
screw-in receptacles below the terminal block (on the rear panel of the unit).
These DC fuse requirements are as follows:
Modem Operation – 3 Amp/250 volts 20mm x 5mm Slow-blow fuse.
o
BUC Operation – 6.3 Amp/250 volts 20mm x 5mm Slow-blow fuse.
