NetPerformer Hardware Installation Guide
2-4 Memotec Inc.
• Equipment that is directly connected to the voice interfaces can be placed much
farther away. Up to 2750 meters (9000 feet) of cable is permitted between each
NetPerformer analog interface and its attached equipment.
NOTE: Distance may be an important factor for an E&M interface on the SDM UAC unit.
If the PBX and the NetPerformer UAC unit are not near each other (in the same
room, for example) then their AC grounds may not be the same. See “E&M
Grounding Considerations” on page 3-26 for a workaround.
Environmental
Requirements
For trouble-free operation of the SDM-9XXX Series unit, its location must satisfy the
following environmental criteria:
• Operating temperature: 0C to 50C (32F to 122F).
NOTE: Above 3048 meters (10 000 feet) altitude the maximum operating
temperature of the unit drops from 45°C to 35°C.
• Storage temperature: -20C to 65C (-4F to 149F).
• Relative humidity: 10% to 90%, non-condensing.
• Maximum operating altitude: 4572 meters (15 000 feet)*.
• Ventilation requirement: leave 5 cm (2 inches) of unobstructed space around the
unit. All unused slots must be closed with a plate.
