Warnings
Warnings
The following warning statements identify conditions or practices that can
result in personal injury or loss of life.
Dangerous voltage or current may be present — Disconnect power and remove
battery (if applicable) before removing protective panels, soldering, or
replacing components.
Do not service alone — Do not internally service this product unless another
person capable of rendering first aid and resuscitation is present.
Remove jewelry — Prior to servicing, remove jewelry such as rings, watches,
and other metallic objects.
Avoid exposed circuitry — Do not touch exposed connections, components or
circuitry when power is present.
Use proper power cord — Use only the power cord supplied or specified for
this product.
Ground product — Connect the grounding conductor of the power cord to
earth ground.
Operate only with covers and enclosure panels in place — Do not operate this
product when covers or enclosure panels are removed.
Use correct fuse — Use only the fuse type and rating specified for this
product.
Use only in dry environment — Do not operate in wet or damp conditions.
Use only in non-explosive environment — Do not operate this product in an
explosive atmosphere.
High leakage current may be present — Earth connection of product is essential
before connecting power.
Dual power supplies may be present — Be certain to plug each power supply
cord into a separate branch circuit employing a separate service ground.

7600REF — Installation and Safety Manual 9
Cautions
Cautions
The following caution statements identify conditions or practices that can
result in damage to equipment or other property
Use correct power source — Do not operate this product from a power source
that applies more than the voltage specified for the product.
Use correct voltage setting — If this product lacks auto-ranging power sup-
plies, before applying power ensure that the each power supply is set to
match the power source.
Provide proper ventilation — To prevent product overheating, provide equip-
ment ventilation in accordance with installation instructions.
Use anti-static procedures — Static sensitive components are present which
may be damaged by electrostatic discharge. Use anti-static procedures,
equipment and surfaces during servicing.
Do not operate with suspected equipment failure — If you suspect product damage
or equipment failure, have the equipment inspected by qualified service
personnel.
Ensure mains disconnect — If mains switch is not provided, the power cord(s)
of this equipment provide the means of disconnection. The socket outlet
must be installed near the equipment and must be easily accessible. Verify
that all mains power is disconnected before installing or removing power
supplies and/or options.
Route cable properly — Route power cords and other cables so that they ar not
likely to be damaged. Properly support heavy cable bundles to avoid con-
nector damage.
Use correct power supply cords — Power cords for this equipment, if provided,
meet all North American electrical codes. Operation of this equipment at
voltages exceeding 130 VAC requires power supply cords which comply
with NEMA configurations. International power cords, if provided, have
the approval of the country of use.
Use correct replacement battery — This product may contain batteries. To
reduce the risk of explosion, check polarity and replace only with the same
or equivalent type recommended by manufacturer. Dispose of used bat-
teries according to the manufacturer’s instructions.
Troubleshoot only to board level — Circuit boards in this product are densely
populated with surface mount technology (SMT) components and applica-
tion specific integrated circuits (ASICS). As a result, circuit board repair at
the component level is very difficult in the field, if not impossible. For war-
ranty compliance, do not troubleshoot systems beyond the board level.

Frame Installation
Frame Installation
Follow the instructions below to unpack and install the 7600REF frame. For
more detailed instructions and cabling the rear of the frame, refer to the
7600REF Instruction Manual.
Unpacking
Carefully unpack the unit from its packing box and check for signs of
damage. Check the contents of the box against the packing list and your
original order to ensure that you have received the correct parts.
In the event the unit has been damaged or does not match your order,
contact the Thomson Grass Valley Sales office listed on Contacting Grass
Valley on page 2.
Rack Mounting
The 1 RU rack frame has integral rack mounting ears on the frame front
cover for direct mounting into a standard 19 inch rack. Carefully place the
unit in your rack and firmly attach it to the rack using four standard rack
screws (not provided).
CAUTION This unit has air intakes on one side of the unit and fan-assisted exhaust vents
on the other side. Ensure that these vents have an unobstructed air flow, to
prevent the unit from overheating. Pay particular attention to ensure that any
rack wiring or cable trays do not obstruct the vents. 60 mm (2.36 in.) of clear
space should be allowed between the vents and any potential obstruction.
Module Installation
No installation of any modules should be necessary. All modules will come
installed in the frame from the factory. The presence of modules depends
on the 7600REF model you have ordered. Software options for the frame
type you have ordered will already be enabled when the frame is received.

Figure 1.
Figure 1. 7600REF Rear Backplane
Grounding Lug
The unit is provided with a single 4 mm (0.16 in.) ground lug on the far left
of the rear panel. Incoming mains ground from the IEC connector is inter-
nally bonded to both the chassis and technical 0V to meet safety require-
ments and performance specifications. The stud allows the addition of an
ground strap, if required, for rack installations.
AC Mains Connection and Fusing
CAUTION The power supply cord is used as the main power disconnection device.
Ensure that the socket outlet is located/installed near the equipment and is
easily accessible.
ATTENTION Le cordon d’alimentation est utilise comme interrupteur général. La prise de
courant doit être située ou installée à proximité de l’équipement et être facile
d’accès.
The power supplies within the unit are a switch mode design and are
auto-sensing to handle a wide input voltage range. See Specifications on
page 15.
Each 7600REF model is fitted with two AC mains power supplies. Each
power supply has its own dedicated IEC mains plug on the rear of the unit.
You should receive the correct line cord for your line standard in the ship-
ping box.
Module Cabling
Cabling of module BNCs and Sub-D connectors depends upon the frame
model type and what modules are included with the model. Refer to the
7600REF Instruction Manual for details on cabling the required connections.
