5.2 Output Wires for Terminal Devices (Classic
Plus)
Output wires will already be installed into the circuit board of
the Espire Elbow Classic Plus. They can easily be retrieved from
inside of the forearm and connected to the desired device. The
wires will be colour coded and simply need to be plugged into
the appropriate terminal device. Wires that are not needed can
be tucked away into the forearm.

5.3 Quick Disconnect Wrists (Classic Plus)
Wiring
The hand-open, hand-close, and power output cables will
plug into a single coaxial unit which fits through the centre of
the quick disconnect wrist.
1.
Plug the orange (hand-open)
cable into the left plug labeled
“2”, then plug the green (hand-
close) cable into the right plug
labeled “2”.
2. Plug the red (power) output
cable into the plug labeled “1”.
Note: If the two 3-socket connectors (hand-open/
hand-close) are attached to the wrong plugs labeled
“2”, the open-close functions will operate in reverse.
Note: If fitting with a short wrist or friction housing but
still want batteries above elbow, the cable option uses
different connector. Therefore, if using power with the
Classic version it would require external wiring if power
proximal to the elbow joint was needed. If integrated
power is desired, the Classic Plus would be advisable.
5.4 Electronic Wrist Rotators (Classic Plus)
Electronic wrist rotators require a battery that supplies an
additional plug for the wrist power (See section 3.1). To connect
a wrist rotator, install the battery in the forearm and use that
unique system. The wire should be attached to the battery, run
though the distal end of the forearm, and connected to the
wrist. Contact the wrist manufacturer for more information.
