COMSPHERE 3000 Series Carrier
Power Transformer Unit Installation
The carrier derives its low voltage ac power from the power transformer unit mounted at the bottom of the carrier.
Preinstallation Inspection
Check the unit for physical damage. Ensure that the unit has not been damaged, possibly causing a short circuit of internal components. If the power transformer unit shows signs of shipping damage, report this immediately to your shipping representative and also to your AT&T Paradyne representative.
