General Information
This section provides information on the product configuration, reach and coverage, support
requirements and electrical power requirements.
Certified Component
Environmental Factors
The equipment is intended for indoor use for normal dental applications within these
ranges:
Reach and Coverage
The reach of the system is measured from the tip of the cone with the arm fully
extended and the cone pointing back toward the pivot of the wall plate. This
measurement method accommodates the normal positioning of the Tubehead to the
patient. A patient can therefore be positioned without difficulty with the chair located
within a radius outward from the pivot point to the dimensions listed below.
The Gendex expert®DC is available with three different lengths of the horizontal arm.
This allows the system to have three different areas of reach. The lengths available
allow reaches of 59 inches (150 cm), 69 inches (175 cm), or 79 inches (200 cm).
Component Reference No. Label Location
Tubehead 110-00210G1 Underside of Yoke
Master Control 110-0205G1 Underside of Master Control
Collimator 112-0951G1 Inside of Cone
Temperature 10 to 40° C (50 to 104° F)
Air Pressure 700 hPa to 1060 hPa (0.7 bar to 1.060 bar)
Humidity 30 to 90 percent

Expert DC Installation Manual

NOTE: The reaches listed are for the 79-inch (200 cm) arm supplied with the 8-inch (20 cm) cone.
Using the optional 12-inch (30 cm) cone will reduce the arm reach by 4 inches (10 cm).

Electrical Power Requirements
The system requires a three-wire electrician-supplied power supply: A ground wire and
two power lines: (L) Line and (N) Neutral.
NOTE: The line cord option can be purchased with the system. This option is only
permitted for 120 V ac installations. It is not recommended for voltages other than
120 V ac. To prevent damage to the unit, before installing the line cord:
•set the AC Input Selector Jumper to the proper voltage range of the
supplied mains, and
•cut jumper JP1 on the Converter Board (4mm gap minimum) this
enables the Neutral line fuse. Refer to Electrical Power Connection
on page 2-23 to ensure proper wiring of the device.

Preinstallation
032-0204-EN Rev 4 1-7
Wall Support Considerations
Verifying the wall support capability is the responsibility of the installer. Appropriate
fasteners are included for single-stud installation only.
WARNING
The installer must use the supplied 3 1/2” lag bolts, flat washers, and split
lock rings, when installing an Expert DC system. Failure to comply may result
in the X-ray device falling off the wall and an injury may occur.
Substituting or replacing any mounting hardware that is provided with the equipment
may void the warranty. Any property damage or personal injury resulting from an
improper installation could become the responsibility of the installer(s).
The wall support and mounting hardware for the Gendex expert®DC unit must
withstand these maximum forces:
The Master Control unit of the Gendex expert®DC system is designed to be mounted
on a single wood 2"x 4" stud or equivalent wall support. The hole pattern on the back
plate of Master Control is configured to accommodate these types of installation:
•Mounted to two wooden wall studs spaced at 16" (41 cm) (using the optional Wall
Plate D800WPEXPERT)
•Mounted to a solid wall (concrete or similar construction)
•Mounted to a wall supported by steel studs (using the optional Wall Plate,
D800WPEXPERT and the optional Backing Plate, D800BPEXPERT)
•Mounted in a pass-through box or cabinet system
Use the template provided to position the Master Control properly. The template also
specifies the correct placement of the Master Control Touch Panel when mounted
remotely.
For all installations, the bottom of the Master Control unit, or the Wall Plate to which it
is mounted, should be located at approximately 39" (99cm) above the floor. (The large
range of travel of the suspension arm provides some flexibility in the vertical position.)
A summary for each type of mounting is given in the table that follows:
Shear load 60lbs (27 kg)
Withdrawal force at each mounting screw/bolt 400 lbs (182 kg)
Load moment capability of wall fabrication and
attachments to the building structure 850 ft. lbs (118 kg m)

install junction box (1)

Expert DC Installation Manual
032-0204-EN Rev 41-8
Additional Kits Available
Read the installation instructions provided with the kits before starting to install
Gendex expert®DC. Some kits require that additional access holes be made before the
Master Control or the Mounting Plate for the Master Control is mounted.
NOTE: Unless additional kits are purchased, the exposure switch on the Master
Control Touch Panel and the attached Coil-Cord Exposure Switch are the only
switches available. In order to comply with regulations and proper x-ray
practices, the Master Control Touch Panel or additional exposure switches
must be located where the operator can view both the patient and the
technique factors prior to the exposure.
In the event you are not installing an application described in the manual, please contact your
Gendex Sales Representative, who can consult with Gendex Engineering Department, prior to
install.

indicates when x-rays are being emitted. The exposure
switch on the Master Control Touch Panel is disabled.
Remote Cable Adapter Kit - Part

strip instead of the modular connector. This may be
required if the control cable is run in conduit.

2Installation
Ensure that all preinstallation requirements are completed prior to beginning installation.
1. Are all the wall support requirements adequate for mounting the unit?
2. Have all the electrical power requirements been met?
3. Do all wires have proper routing locations?
Tools required for installation:
•Metric Allen hex wrench set
•Screwdrivers (slot/Phillips)
•Drill and drill bits for wall mounting
•Sockets and ratchet driver for wall mounting
•Fluke model 73 DVM equivalent or better
•Level
Install Master Control Touch Panel
The recommended configuration is to mount the Gendex expert®DC with the Master
Control inside the X-ray room and the Master Control Touch Panel outside of that room.
(When located apart from the Master Control, the Master Control Touch Panel is referred
to as the “Remote Touch Panel.”)
The Master Control Touch Panel can be mounted directly on the Master Control. This is
not recommended as it is important to be able to view the technique factors prior to the
exposure. (When attached directly to the Master Control, the Master Control Touch
Panel is referred to as the “Local Touch Panel.”)
Both the Remote and Local mounting location of the Touch Panel are described in the
section Complete the Installation, page 2-26.
For Local Touch Panel procedures, skip to Install Master Control, page 2-4.
Remote Touch Panel procedures are as followed.
1. Open the shipping carton and locate the Master Control Touch Panel, the
Mounting Plate, and the 50-foot (15-meter) Control Cable in the top
portion of the shipping carton.

2. Set the Master Control Touch Panel aside to be installed later.
NOTE: Before attaching the Mounting Plate, to ensure you orient the plate correctly,
take note of the two mounting studs at the top of the plate.
3. Refer to the supplied Mounting Template to select the mounting location.
Attach the Mounting Plate in the desired location with the three supplied
Phillips head screws and wall anchors at positions A. Or, the three wood
screws provided with the plate may be used to mount the plate over a
wood 2x4 stud at positions B.

NOTE: In the following step, route the Control Cable in compliance with local codes.
The cable can also be run to an electrical box. If installing the Master Control
on the optional Wall Plate, refer to step 3 on page 2-6 for routing instructions
for the control cable at the Wall Plate.
4. Fish the Control Cable from the Master Control Touch Panel to where the
Master Control will be located. Extend the cable out through the wall to a
length that will extend past the bottom front of the Master Control (once
mounted).
