INFORMATION
The E-MAG knee joint features integrated polarity protection: In case of incorrect polarity, a short-circuit
is avoided by turning off the electronics. If the E-MAG knee joint system fails to indicate operational
readiness for no apparent reason (see Section 5.2) after the cables are connected, please check the
polarity.

NOTICE
Risk of cable damage. Shortening, extending and frequent bending can destroy the cables between
the joint and electronics as well as between the battery and electronics. If possible, do not bend the
electronics cables until they are ready to be fastened into their final position.
Install the cable from the E-MAG knee joint to the electronics. If necessary, route it in flat loops
until it lies against the socket without tension between the knee joint and electronics (Figure 47).
Press the loops onto each other and fasten the cable to the casing with adhesive tape.
Electric connections can oxidise. Protect contacts and cable transitions with 633F11 Silicone
Grease as indicated in Figure 48.
