Ac Mains Power; Fuse Holder; Mains Voltage Selector; Power Cord - DEVA Broadcast DB3010 Maintenance And Operating Manual

FUSE HOLDER

The fuse holder is placed inside the unit, next to the voltage selector. Apply downward pressure
and pull the cap outward to access the 5mm mains fuse. The reverse process will release the cap.

MAINS VOLTAGE SELECTOR

Before connecting the AC Power, make sure that the internal Power Switch and the fuse rating
are in accordance with the mains supply at your location.
DB3010 Power Supply Factory Settings are:
- 100 - 240 VAC
- 1 Amp Fuse
CAUTION:
Permanent damage will result if improper AC supply voltage is applied to DB3010
device. Your warranty does not cover damages caused by applying improper supply voltage, or use
of an improper fuse.

POWER CORD

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

GROUND LOOPS

Because the unbalanced RF INPUT of the DB3010 is chassis-ground-referenced, a mains
frequency or RF ground loop could be formed between the input or output cable shield grounds
and the AC power cord ground. A 'ground-lifting' AC adapter may well remedy such a situation,
although the chassis somehow must be returned to earth ground for safety. Generally, being
screwed-down in the equipment rack will satisfy the safety requirement.
