4.0 Hardware Installation
4.1 Introduction
This section provides instructions for installing the FreeSpace®
E4 system hardware on a tabletop or in a rack.
4.2 Included accessories
The following accessories are shipped with the E4 unit in the
FreeSpace E4 System Accessory Kit (PC030105).
• 2-terminal input connectors (6) – For wiring
Auto Volume mics to the
SENSE MICROPHONES jacks
• 3-terminal input connectors (2) – For wiring
equipment to the AUX MIC/LINE 3 jacks
• 4-terminal input connectors (3) – For wiring
equipment to the ZONE 4 LINE OUT,
PAGE/MIC/LINE 4, and
DIRECT IN/CONTROL jacks
• 2-terminal output connectors (5) – For wiring speaker cables to the ZONE OUT jacks
• Rubber feet (4) – For installing the E4 unit on
a level surface
4.3 Placement guidelines
• Place the E4 unit where it is protected from heat and allowed
adequate ventilation.
• Place the E4 unit away from direct heat sources, such as heating vents and radiators.
• Make sure that air can circulate freely behind, beside, and
above the unit. Allow six inches on all sides.
Installer’s Note: Do not allow the chassis to exceed the
maximum operating temperature of 50° C (122° F). Be aware
of conditions in an enclosed rack that may increase the temperature above room-ambient conditions.
4.4 Shelf mounting the E4 unit
The E4 unit is ideal for shelf mounting. The included accessory kit
contains four rubber feet for the bottom of the E4 chassis. The
rubber feet will protect the surface on which the E4 unit is
installed and help prevent movement of the E4 unit. Be sure to
follow the “Placement Guidelines” previously described when
choosing a location for the E4 unit.
• Replacement voltage label (2) – Used on
the OUTPUT VOLTAGE selection switch
• FreeSpace Installer™ software CD –
Contains application software for programming the E4 system

Rack ears
(8) #8-32 x 1/2 in
The E4 unit requires three 1.75" (4.4 cm) rack space units with a
16" (40.6 cm) inside depth (including the rear supports). When
mounting, use four screws with washers to prevent marring the
front panel. Neoprene rubber washers are a good choice
because they grip the screw head and prevent the screws from
backing out from vibration or during transportation.
Installer’s Note: If the E4 unit is to be transported while
mounted in a rack, be advised that the rear of the E4 unit
must be mechanically supported. Install a shelf under the unit
or use brackets in such a way as to support the rear of the
unit. Failure to use proper mounting hardware may result in
damage to the E4 unit during transport.
