Tempest 900 - Power Connections

23
Tempest900 2-Channel Operating Manual
• The rear panel must be accessed for making wired system connections.
• The Tempest BaseStation should be in a location that has adequate ventilation and is not subject to extreme temperatures and humidity.
• Avoid areas subject to water or rain.
• Always use a stable and secure platform or rack mount system.
Power Connections
The Tempest BaseStation can be powered by AC or DC power, and uses an auto-switching power supply; therefore, if both AC and DC are
connected, the BaseStation will automatically switch to DC in the event AC power is interrupted.. The front panel ON/OFF switch controls AC
and DC power coming into the BaseStation. If AC and DC are both connected, the DC will act as a power supply backup in the event AC power
is interrupted.
AC Power Connection
• Always connect the power cord to the Tempest BaseStation before connecting to the outlet.
• Tempest BaseStations are powered by an internal power supply. The cord to connect the internal power supply to the mains supply
must conform to the following:
» The mains power cord shall have an IEC C13 connector at one end and a mains power plug at the other end.
» An IEC C 13 plug has three pins, the centre pin carrying the earth/ground. The other two pins carry neutral and live circuits.
» The conductors of the mains cords shall have adequate cross-sectional area for rated current consumption of the equipment.
» The mains plug that connects to the mains supply must be approved for use in the country where the equipment is to be used.
» The mains power cord must be an IEC mains 3-wire grounding power cord complying with standard IEC60320; IEC320/C13.
• Mains power cords used in the US must also comply with standard UL817.
• Only use AC power from 85 to 260 VAC at 50 – 60 Hz.
DC Power Connection (Battery)
• To power the Tempest BaseStation from DC power, you must provide an appropriate DC power input cable.
• The DC power input jack on the BaseStation is a Switchcraft 722RA.
• The mating plug is a Switchcraft S760 - 2.1mm x 5.5mm power plug. The connector should be wired as center positive.
• Always use appropriate wire of an acceptable gauge and length for your application. The minimum recommended wire is 26 gauge at
not more than ve feet. If 10 feet is required, the minimum gauge would be 24.
• Only use DC power from 11 to 32 VDC. The Tempest BaseStation will draw approximately 12 Watts (990mA at 12VDC).
