Electrical safety / EMC compatibility
MKE
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 MKE
does not know the final assembly of the complete device in which the MKE 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 MKE 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 MKE 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 MKE.
Warranty
• All connections have to be carried out in the off-state of the MKE (i.e. without power
supply)
• The MKE is an electrostatic sensitive device. Avoid any electrostatic charges !
• Do not solder directly to any of the pin headers but use female connectors to make the
connections between the MKE and your application. We offer suitable cables.
• If external momentary switches or LEDs are connected to the MKE they have to be
soldered in the off state of the MKE (i.e. without power supply)
• Applying a negative voltage or a positive voltage beyond +5V at the ADC inputs (ST3,
ST4, ST5, ST6) will destroy the circuit.
• Avoid short cuts while MKE is powered !
• Ignoring any of these items will cause warranty loss !
• Return of the MKE within the 2 weeks return time limit (valid only in Germany) is only
possible if all these items have been met. MKE that have been soldered by the customer
cannot be taken back (e.g. if external momentary switches or LEDs have been soldered to
the MKE by the user).
