4.3 Power Information

WARNING
System cables MUST NOT be cut while power
is ON. This will short the battery and damage
the system. Any damage caused in this way will
void the bebionic warranty.
Power Cables
A bebionic hand uses five actuators and therefore requires a higher current supply than single motor devices. This
can be accommodated safely using bebionic power cables. Other power cable types may not be efficient or safe.
However, cables from other manufacturers may be adequate for signaling application.
Low Power Condition
When the battery capacity approaches its lower limit the hand operation will slow down and begin to respond only to
OPEN signals. This occurs to ensure the hand stops in an open position to prevent the hand becoming locked onto an
object when the power has been completely drained from the battery. The battery must be recharged for further use.
!
CAUTION
When attaching or detaching a bebionic hand
to/from a prosthesis, it is important to first
disconnect power by moving the battery switch to
the OFF position.
This is to avoid a potential current surge to the
hand when it connects/disconnects with the
power source.
Battery Switch / Charging Module
An ON/OFF switch is integrated into the charge module. The switch
disconnects power completely, and has two positions. When the switch is
positioned closest to the charge port, power is OFF and the battery can be
charged by connecting the lead from the bebionic charger. When the switch
is furthest away from the charge point, power is switched ON. The battery
cannot be charged in this position.
The ON/OFF switch / charge module is fitted to the battery and requires an
additional connector cable to link to the hand.
The connector cable for EQD hands, as shown on page 28, is supplied with
each battery. For short wrist or friction wrist options a different connector
cable (CBBHA72), as shown on page 29, will need to be ordered separately
and connected to the battery pack in place of the EQD connector cable.
A small laminating dummy is included in the kit. Prior to lamination this should be placed in a suitable location and
orientation on the forearm model. The position chosen should allow sufficient space between the inner and outer
sockets to allow easy access to the switch and plug point by the user.
WARNING
It is NOT recommended to route the power
supply to the hand without passing through the
switch.

WARNING
The prosthesis MUST NOT be worn whilst the
batteries are charging.
