The detachable IEC-type power cord is supplied with the unit. The individual cord conductors
may be color-coded in either of two ways:
1) In accordance with US standards:
BLACK = AC “HOT”
WHITE = AC NEUTRAL
GREEN = EARTH GROUND
2) To European CEE standards:
BROWN = AC “HOT”
BLUE = AC NEUTRAL
GREEN/YELLOW = EARTH GROUND
OPERATING RECOMMENDATIONS
For the normal and reliable operation of the DB8009-MPX device we recommend to follow the
next list of instructions:
• Please, install the unit only in places with good air conditioning. The unit has been designed
for operation within an ambient temperature range extending from 10 to 50°C. But because
adjacent, less efficient equipment may radiate substantial second-hand heat, be sure that the
equipment rack is adequately ventilated to keep its internal temperature below the specified
maximum ambient. When installing, leave a clearance of at least 1 cm around the equipment
to allow air to pass freely.
• We do not recommend installation in rooms with high humidity, dusty places or other
aggressive conditions.
• Although it is expected that a DB8009-MPX will be installed close to exciters (or transmitters
of even higher-power!), please practice reasonable care and common sense in locating the
unit away from abnormally high RF fields.
• Please, use only already checked power supply cables and sources. The shielded cables
usage is strongly recommended.
• We strongly recommend connecting the device only to reliable power supply sources. In
case of unstable power supply, please use UPS (Uninterruptible Power Supply).
• Please, use the device only with placed top cover to avoid any electromagnetic anomalies
which may cause problems of the normal functionality of the unit.
• Please, connect DB8009-MPX only to good quality Internet connection. This is very
important for the normal remote operation of the unit.
• Please, check if your network settings pass through all the data traffic required for the normal
operation of the DB8009-MPX unit.
RADIO FREQUENCY INTERFERENCE (RFI)
Although we have anticipated DB8009-MPX installation in the immediate proximity of
broadcast transmitters, please do practice some care using the unit away from abnormally high RF
fields.
