Telephone Lines Unsafe Voltages
As unsafe voltages (Telecommunication Network Voltages) exist on
ISDN lines, safety precautions must be taken to prevent contact with any
dangerous area of the system.

ARNING
■
The ISDN cable(s) must remain disconnected from the
telecommunications system until the card has been
installed in the system.
■
The installation of the card in the host system must be
done in a way that ensures at least 2mm of air gap
between the Printed Circuit Board (PCB) card and any
other components in the host system, so that the
unsafe area remains located only on the ISDN card.
■
The modem card must only be used in a host system
with a screw-down cover / lid in order to protect the
operator.
Telephone Wiring Warnings
Never install telephone wiring during a lightning storm. Never install
telephone jacks in wet locations unless the jack is specifically designed
for wet locations. Never touch non-isolated telephone wires or terminals
unless the telephone line has been disconnected at the network interface.
Any intervention on the card or in its proximity should be made with the
telephone connector unplugged.
Observe Dangerous Procedure Warnings
Warnings precede potentially dangerous procedures throughout this
manual. Instructions contained in the warnings must be followed. You
should also employ all other safety precautions which you deem
necessary for the operation of the equipment in your operating
environment.
