Electrical safety / EMC compatibility
DIAL ELECTRONIC (abbreviated "DE" in the following) 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 (e.g. rotary encoders, switches, LEDs, power supply, case/housing). The
manufacturer of DE does not know the final assembly of the complete device in
which the DE 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.
Electronic basic knowledge is required to install DE and to connect the rotary
encoders, switches and LEDs. 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.
Please pay attention to the following items:
The power supply used in combination with the DE 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 whith open
mains voltage access (e.g. via mains lead, pcb tracks, electronic parts).
On the DE preventing measures against electromagnetic radiation are taken (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 DE.
Warranty
• Do not solder directly to any of the pin headers but use female connectors to
make the connections between DE and the rotary encoders, switches and LEDs.
A cable set that contains all required connectors and cables is included with DE.
• Carry out all connections in the off-state of DE (i.e. when powered-off only) !
• Do not connect any voltage to the pin headers but only the encoders, switches
and LEDs as described in this manual.
• DE electronics is an electrostatic sensitive device. Avoid any electrostatic charges
!
• Avoid short circuits !
• Ignoring any of these items will cause warranty loss !
• Return of the DE within the 2 weeks return time limit (valid only in Germany) is
only possible if all these items have been met. Return of used cable sets is not
possible. We also cannot take back modules that have been soldered by the user.
