Busch & Mueller E-werk Instruction Manual

E-WERK
Bike-mobile hub dynamo powered supply unit for electronic devices
Instruction manual. Please study carefully before using E-WERK!
Capable of powering small electronic devices – e.g. mobile phone, MP3 player, GPS (also 12 V models for
cars) – or of charging batteries – NiCd, NiMh, Li and Pb. Translates energy created created by the hub
dynamo.
CAUTION: Busch & Mueller vouches solely for a faultless functioning of the E-WERK. Exempt from liability is
any damage to connected devices of all kinds. It cannot be guaranteed that the E-WERK is able to power all
connectable devices. For example, some mobile devices only use their internal battery during operation and
cannot be charged at the same time, also not by the E-WERK. Please contact the device's manufacturer for
information! However, the E-WERK is able to charge an external battery, e.g. our buffer battery 461A (not
included). With it, such devices can be recharged after the trip. Other rare exceptions are devices whose
technical properties prevent them from being charged while riding the bike because of voltage fluctuations.
They, too, can be powered by the E-WERK using an adequate buffer battery. Further information can be found
on our website www.bumm.de

Mounting on a bike

The E-WERK can be fastened to a large variety of frame tubes in any suitable place by using rubber bands (3) or
cable straps (4). The E-WERK is splash and rain water proof!
Mounting with cable straps: Pull one cable strap each through the opposed slots in the fixing bracket, guide them
around the frame tube and tighten.
Without mounting: The E-WERK can be carried in any bag that allows a cable connected to the hub dynamo to
exit. In this case, the fixing bracket can be removed.

Connection to a dynamo/power source

The E-WERK works with all hub and tire driven dynamos without electronic voltage limitation. Connected to
dynamos with integrated limitation, the E-WERK can give off a maximum of 7 V.
Connect E-WERK to the dynamo with the bared ends of the connection cable (5) (see the following connection
options). Connect the other end to the input (IN) of E-WERK (remove cap from plug connection first). By
tightening the screw caps, those connections can be made splash and rain water proof!
