For peak performance, locate the DX-GB so that air can flow over and
around the case.
Make sure that the mounting position minimizes bending and flexing
stresses on the motor cables, especially with moving motor/wheel
suspension.
Use all three mounting points to attach the DX-GB.
The use of M5 or #10/32 screws that engage up to 10mm/0.39" into the
case is recommended.
Warning:
Regardless of mounting orientation, protect powerchair wiring and
connectors from the risk of damage, water splashes and/or water
ingress, and route the cabling so that water will not run down into the
connector system. The use of cable boots is highly recommended.
Do not mount the DX-GB in a position where the user can come into
continuous contact with the unit. The case temperature can
exceed 41°C.

Connections and Wiring
The DX-GB has two connector plates located along the front panel of the case that
contain DX BUS (x2) and Drive Control Input (DCI) connections. The batteries, motors
and park brakes are connected using the cables extending from the case.
Chair design and specification shall ensure that the motor and
controller cannot be overloaded in normal use and intended
operating environment, to ensure that adequate braking torque is
available at all times.
Ensure that all wiring is suitably restrained to prevent snagging.
Connecting looms must have connector housings fitted to prevent
incorrect connections.
Before making any connections to the DX-GB, disable the
powerchair by one of the following means to prevent accidental
movement:
•
Place the battery circuit breaker in the open position or remove
the battery fuse,
•
Disconnect the motor or batteries, and/or
•
Elevate the drive wheels.
