D.2.5 Connecting the 24 to 48 VDC Version
The 24 to 48 volt DC powered version of the standalone modem is designed
to operate on an exchange/PABX battery. The supply requirements are 24-
48 VDC, 0.5A max. DC source must be SELV.
The modem power connection is via a 2 metre cable, stripped and tinned
ready for connection to a terminal block.
Connect the red wire to the ground terminal and the black wire to the
–24 to –48 volts DC supply. Double check the connections before turning
the modem on. If the connections are reversed, or the supply voltage is too
high, the fuse will blow. Use a 500mA(T) 250V fuse.
