CAUTION – IF THE MODEM IS OPERATED IN A VEHICLE OR MOVABLE INSTALLATION,
MAKE SURE THE UNIT IS STABLE. OTHERWISE, EN 60950 SAFETY IS NOT GUARANTEED.
Sect. 3.3 Ground and Power Connections
Electrical Installation
CAUTION – CONNECT THE MODEM TO A POWER SYSTEM THAT HAS SEPARATE
GROUND, LINE AND NEUTRAL CONDUCTORS. DO NOT CONNECT THE UNIT WITHOUT
A DIRECT CONNECTION TO GROUND.
The modem is rated for operation over the range 100 to 240 volts AC. It has a maximum power
consumption of 250 Watts (when equipped with a 150W BUC power supply), and draws a
maximum of 2.5 Amps.
The installation and connection to the line supply must be made in compliance to local or
national wiring codes and regulations.
The unit 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, NEMKO, DEMKO,
BS1636A, BSI, SETI, IMQ, KEMA-KEUR and SEV.
Fuses
CAUTION – FOR CONTINUED OPERATOR SAFETY, ALWAYS REPLACE THE FUSES WITH
THE CORRECT TYPE AND RATING.
The 115/230 volt AC-powered modem is fitted with two 20mm T3.15A (P/N 3.15ASB-IEC)
Slo-Blo fuses – one each for line and neutral connections. They are contained within a fuse
holder that is press-fit into the body of the IEC power module.
Optional -48V DC Units: These units are fitted with two 20mm Slo-Blo fuses – one each for
positive and negative connections. They are contained within a fuse holder that is press-fit into
the body of the IEC power module.
• For 42 to 60 volt DC operation, use T5.0A fuses if the modem has no BUC power supply.
• For 42 to 60 volt DC operation, use T8.0A fuses if the modem is fitted with an internal BUC
power supply.
Optional -24V DC Units: The 24 volt DC-powered modems are fitted with two 20mm Slo-Blo
fuses – one each for positive and negative connections. They are contained within a fuse holder
that is press-fit into the body of the IEC power module.
