It is a condition of approval that the power required by the host and the total of all adapter cards
installed within the host environment, together with any auxiliary apparatus, does not exceed the
power specification as stated in the Technical Reference Material of the host apparatus.
The power requirements for the MULTIMODEMISI are:
Modem operating voltages:
Modem Power Consumption:
In order to maintain the independent approval of this card, 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 following table are maintained. A hazardous voltage is one which exceeds 42.4V
peak a.c or 50V d.c. If you have any doubt, seek advice from a competent engineer before installing
other adapters into the host equipment.
The equipment must be installed such that with the exception of connection to the host, clearance
and creepage distances shown in the following table are maintained between the card and any other
assemblies which use or generate a voltage shown in that table. The larger the distance shown in
brackets applies where the local environment within the host is subject to conductive pollution or dry
nonconductive pollution which could become conductive due to condensation. Failure to maintain
these minimum distances would invalidate approval.
Except at the edge connector which plugs into the host's expansion slot, clearance distance (Xmm)
and creepage distance (Ymm) as given in the table above, must be maintained between the
communication card and any assemblies which use or generate hazardous voltage.
This apparatus has been approved for the use of the following facilities:
• Auto-calling
• Loop disconnect and MF dialing
• Phone number storage and retrieval by a predetermined code
