Electrical safety / EMC compatibility
MBP25 is a so-called OEM product (OEM original equipment manufacturer) that
cannot be used independently but has to be combined with additional electrical or
electronical equipment to become a working device (suitable keyboard, pitch bend
and modulation wheel, rotary or fader potentiometer, power supply, case/housing).
The manufacturer of MBP25 does not know the final assembly of the complete
device in which the MBP25 is used as a part of the complete device. The final
responsibility with regard to electrical safety and electromagnetic compatibility is
up to the user who is assembling the complete device.
Please pay attention to the following items:
The power supply used in combination with the MBP25 has to be a closed type (in
Germany a power supply with VDE approval is required). Normally an AC adapter
with plastic case is used. It is not allowed to use open power supplies with open
mains voltage access (e.g. via mains lead, pcb tracks, electronic parts).
On the MBP25 electronics preventing measures against electromagnetic
radiation are met (e.g. RF filters at the power supply input and the MIDI lines). But it
is impossible to estimate to what extend the components added by the user affect
the EMC properties of the complete assembly. Therefore the complete device has
to be shielded against electromagnetic radiation (incoming and outgoing). These
demands are normally met by a closed metal case that covers the complete
assembly. The metal case should be connected to GND of the MBP25.
Warranty
• All connections have to be carried out in the off-state of the MBP25 (i.e. without
power supply)
• The MBP25 electronics is an electrostatic sensitive device. Avoid any electrostatic
charges !
• Do not solder directly to any of the pin headers but use connectors to make the
connections between the MBP25 and your application.
• Applying a negative voltage or a positive voltage beyond +5V at any of the inputs
will destroy the circuit.
• Avoid short cuts while MBP25 is powered (e.g. caused by metallic or conducting
supports) !
• Ignoring any of these items will cause warranty loss !
• Return of the MBP25 within the 2 weeks return time limit (valid only in Germany)
is only possible if all these items have been met. MBP25 that have been soldered
or modified by the customer cannot be taken back.
Electronic basic knowledge is required to install the MBP25 electronic kit. If
you are not sure whether your knowledge is sufficient please consult an expert.
We cannot take back modules that became defective because of wrong
installation or wrong connection of the controls or voltages. We also cannot
take back modules or cables which have been soldered by the user.
