KRAMER: SIMPLE CREATIVE TECHNOLOGY
Overview
3 Overview
The Kramer RB-8 is a high-performance, high-voltage power supply that
supplies power to up to eight external units. Each output channel includes a
power socket and a 2-pin terminal block control port. When the control port
is connected, the contact-closure supplies power to that channel. LEDs on
the front panel indicate which ports are supplying power to their devices.
The RB-8 is housed in a 19-inch, 1U rack-mountable enclosure, and is
powered by a 100–240V AC universal switching power supply. The RB-8
is a model for use in America with 110V AC American power sockets, and
the RB-8E is for use in Europe with 220V AC European power sockets.
“RB-8” is printed on the front panel of both models.
To achieve the best performance:
1
Use only good quality connection cables
to avoid interference,
deterioration in signal quality due to poor matching, and elevated
noise levels (often associated with low quality cables).
Avoid interference from neighboring electrical appliances that
may adversely influence signal quality and position your Kramer
RB-8 away from moisture, excessive sunlight and dust

Installing the RB-8/RB-8E in a Rack
5 Installing the RB-8/RB-8E in a Rack
This section describes how to install the RB-8/RB-8E in a rack.
Before Installing on a Rack
Before installing on a rack, be sure that the environment is
within the recommended range:
Operating temperature range +5º to +45º C (41º to 113º F)
Operating humidity range 10 to 90% RHL, non-condensing
Storage temperature range -20º to +70º C (-4º to 158º F)
Storage humidity range 5 to 95% RHL, non-condensing
When installing on a 19" rack, avoid hazards by taking
CAUTION!!
care that:
1. It is located within the recommended environmental
conditions, as the operating ambient temperature of a
closed or multi unit rack assembly may exceed the
room ambient temperature.
2. Once rack mounted, enough air will still flow around
the machine.
3. The machine is placed straight in the correct
horizontal position.
4. You do not overload the circuit(s). When connecting
the machine to the supply circuit, overloading the
circuits might have a detrimental effect on overcurrent
protection and supply wiring. Refer to the appropriate
nameplate ratings for information. For example, for
fuse replacement, see the value printed on the
product label.
5. The machine is earthed (grounded) in a reliable way
and is connected only to an electricity socket with
grounding. Pay particular attention to situations where
electricity is supplied indirectly (when the power cord
is not plugged directly into the socket in the wall), for
example, when using an extension cable or a power
strip, and that you use only the power cord that is
supplied with the machine.
To rack-mount a machine:
1. Attach both ear brackets to the
machine. To do so, remove the
screws from each side of the
machine (3 on each side), and
replace those screws through the
ear brackets.
2. Place the ears of the machine
against the rack rails, and insert the
proper screws (not provided)
through each of the four holes in the
rack ears.
Note that:
In some models, the front panel
may feature built-in rack ears
Detachable rack ears can be
removed for desktop use
Always mount the machine in the
rack before you attach any cables
or connect the machine to the
power
If you are using a Kramer rack
adapter kit (for a machine that is not
19"), see the Rack Adapters user
manual for installation instructions
(you can download it at:
http://www.kramerelectronics.com)

Connecting the RB-8/RB-8E
6 Connecting the RB-8/RB-8E
To connect the RB-8/RB-8E, as illustrated in Figure 4, do the following:
1. Connect the power cable from each external device to any free power output
port on the RB-8/RB-8E.
2. Connect a switched cable to the CONTROL/GROUND contact of the same
port (for example, from the PL-8 Low Voltage Relay Controller as shown in
Figure 2.)
3. Connect the power cord to the RB-8/RB-8E (not illustrated in Figure 2.)
