6.1 Mounting
There are numerous options available for mounting the compact remote module, such as:
ltray mount
lclamp mount
lbase plate mount
ltube mount
ldrop-in mount
The choice will depend on the type of compact remote (DX2-RJM/-LF or DX2-ACU) being installed and
its user (wheelchair occupant or attendant): for a wheelchair occupant, the tray, clamp and base plate
mount options may be suitable; for a wheelchair attendant, the tube or drop-in mount options may
be more suitable.
6.1.1 Cable routing options
The base of the remote module has two cable exit
recesses located on either side. These allow the bus
cable to extend from the remote at any angle between
vertical and horizontal.
For plate mounting options, this means that the cable
can be routed to the side of the remote module, and
above the plate, as shown in Figure 5.
Figure 5: Cable routing options
Warning:
Limit to ten or fewer the number of times the compact remote module is installed on to a plate if the bus cable is
at 90° to the module; frequent flexing at this angle may damage the cable.

Installation Manual Issue 1
Note:
The mounts shown in the following sections are suggestions only; Dynamic Controls does not manufacture or
supply the mounts. The OEM is responsible for the final design of the mount and its application.
6.1.2 Tray mount
The remote module can be mounted on to any suitable flat
surface, such as a tray, using the fixing holes underneath the
module and two M5 bolts. The maximum torque to fasten these
bolts is 3 Nm – do not exceed this rating as it may damage the
remote module.
This solution is ideal for wheelchair occupants that require the
remote module to be in a more central position, rather than the
standard placements of the left- or right-hand armrests. Figure 6: Fixing centres
6.1.3 Clamp mount
The compact remote has a cylindrical base which is suitable for attaching a cylindrical style clamp or
clip.
Figure 7: Clamp diameter Figure 8: Clamp mount Figure 9: Fixing the clamp mount
6.1.4 Plate mount
The remote module can be mounted using a flat base plate (see Figure 10: Base plate example) and
two M5 bolts. The maximum torque to fasten these bolts is 3 Nm – do not exceed this rating as it may
damage the remote module.
Figure 10: Base plate example
Figure 11: Fixing the base plate
Page 16 - Installation

6.1.5 Tube mount
Figure 12: Tube mount (from above)
The remote module can be fixed on to a tube
using a suitable tube clamp. This solution is useful
for tubes that run perpendicular to the remote
module, as shown left.
The tube diameter will depend on the tube clamp
used, and also the fixing hole centres on the
remote module (30 mm). A tube with an outside
diameter of 15 - 22 mm would be suitable.
Use two M5 bolts to fasten the tube between the
clamp and the base. The maximum torque to
fasten these bolts is 3 Nm – do not exceed this
rating as it may damage the remote module.
Ensure that the DXBUS cable is not pinched when
tightening the tube clamp.
Figure 13: Fixing the tube mount
6.1.6 Drop-in mount
The depth and shape of the base of the compact remote module allows it to be placed into a suitably
designed cradle, such as the drop-in mount shown in Figure 14.
The drop-in mount is ideal for the DX2-ACU attendant remote module, allowing an attendant to
remove and replace the module with ease, and also use the module at a comfortable, safe distance
from the wheelchair. Design the mount to prevent the remote module from falling out accidentally,
or twisting around when used in the mount. A concept drawing is shown below.

Installation Manual Issue 1
6.2 Positioning
6.2.1 DX2-RJM/-LF
Position the remote module such that a typical user's arm is in a natural, comfortable position.
Note:
It is the responsibility of both the manufacturer and the dealer to determine the most appropriate installation
suitable for any single user. This includes, but is not limited to, the placement of the remote module for long term,
comfortable use.
For wheelchair occupants using the DX2-RJM or DX2-RJM-LF, the OEM manufacturer should consider
providing a hand guard at the front of the compact remote module to protect the user's hand against
crushing, such as when manoeuvring under a table.
Warning:
If the wheelchair's remote module has not been fitted with a hand guard, the user should be made aware that
their hand will not be protected from crushing, when, for example, manoeuvring towards or under a table.
When positioning the compact remote, consider the position of the master remote module too. The
wheelchair occupant must be able to see the master remote display when the compact remote
module's display is switched off or when actuators are being used, since actuator feedback is only
displayed on the master remote, not the compact remote.
6.2.2 DX2-ACU
Do not install or place the compact remote module higher than 1.2 m from the ground.
To minimise the risk of snagging, Dynamic Controls recommends permanently fixing the compact
remote module to the rear of the wheelchair, when used as an attendant remote, in line with EN
12184:2009 8.6 Assistant control unit, push handles and handgrips.
For compact remote modules that are not permanently fixed to the wheelchair, limit the length of the
cable between the product and the back of the wheelchair to:
1. minimise the chance of the product hitting the floor, and being damaged if dropped;
2. minimise the chance of the joystick landing on the floor and deflecting, causing a runaway sit-
uation;
3. minimise the chance of snagging the cable on an external object.
The recommended total length of the bus cable, between the product and the back of the wheelchair,
must be no longer than the height above the ground that the product is normally placed. For an extra
margin of safety, reduce the cable length by a further 0.25 m.
Note:
It is recommended that the low force compact remote module (DX2-RJM-LF) is not used as an attendant remote. If
the remote is dropped, the mass of the remote, relative to the joystick deflection force, makes a runaway more
likely than if the full deflection force joystick (DX2-ACU) is used.
6.3 Wiring
For safe and reliable operation, the installation of looms and cables must follow the basic principles of
power wiring.
