Important safety considerations when installing into a host computer system
Installation within a spare slot position
The equipment must be installed such that with the exception of the connections to the
host, clearance and creepage distances shown in the table below are maintained between
the card and any other assemblies which use or generate a voltage shown in the table
below.
Warning: Check that power supply will not be overloaded. Maximum power
consumption of the board is shown in the table on page 5 and 6. The user
should check that the total power drawn by the host computer, the Diva Client
adapter, and any other peripherals, must not exceed the capability of the host
Power Supply Unit. The Diva Client adapter does not draw power from the
ISDN network.
Warning: The ISDN cord(s) must remain disconnected from the
telecommunications system until the card has been properly installed within the
host which provides the necessary protection of the operator.
Proper installation of the ISDN card requires that the ISDN card is screwed to
the metal backplate of the PC. This ensures proper grounding, which is
necessary for your safety.
If it is subsequently desired to open the host equipment for any reason, the ISDN
cord(s) must be disconnected prior to effecting access to the ISDN
communications card.
Warning: It is essential that, when other option cards are introduced which
use or generate a hazardous voltage, the minimum creepages and clearances
specified in the table below are maintained. Suitable user protection to ensure
compliance with EN 60950 should be present on the card. A hazardous voltage
is one which exceeds 42.4V peak a.c or 60V d.c. If you have any doubt, seek
advice from a competent engineer before installing other adapters into the host
equipment.
