European Low Voltage Directive
When correctly installed and maintained, the modem will present
no hazard to the user. When correctly installed the modem will
be connected to the PSTN or a PW and to a Data Terminal
Equipment (DTE), whose modem connections comply with ITU-
T recommendation V.28. The DTE connections are therefore
taken to be safe voltages (less than ± 30 volts).
Ports which are capable of connecting to other apparatus are
defined as SELV. To ensure conformity with EN41003, ensure
that these ports are only connected to ports of the same type on
other apparatus.
