TATEMENTS
The power required by the host and the total of all installed cards shall not exceed the power specification of the
host receiver.
The power requirements for the UTU-712 HDSL card and the ETU-762 desktop unit are provided in the
“Specifications” section on
It is essential that when the equipment is installed in a receiver, the minimum creepage and clearance distances
between the equipment and any devices that use or generate hazardous voltages (42.4V peak AC or 60Vdc) are
as shown in
With the exception of the host connection, the minimum distance must be maintained
between the card and all other assemblies that use or generate the voltages shown. The larger distance shown in
brackets applies where the local environment within the host is subject to conductive pollution or dry non-
conductive pollution that could become conductive due to condensation.
Failure to meet these minimum distances would invalidate the approval.
The analog telecommunications interface is intended to be connected to TNV circuits that may carry dangerous
voltages. The HDSL cord must remain disconnected from the telecommunications system until the card has been
installed and the cover replaced onto the receiver. If the cover needs to be re-opened, the HDSL cord must be
disconnected prior to accessing any internal parts that may carry TNV.
All PairGain HiGain-ETSI shelves and enclosures meet these host receiver requirements.
