We are wishing that you will have a good time for assembling and
using this product.
General:
Tools required for the assembly
Please assure that the following tools are available:
•
a small side cutter
•
a mini soldering iron with a small tip
•
solder tin (if possible 0.5mm diameter)
Safety Instructions
•
All electrical and electronic components included in this kit
shall be used on low voltage only by using a tested and
approved voltage transducer (transformer). All components
are sensitive to heat. During soldering the heat shall be applied
to the respective component for a very short period only.
•
The soldering iron develops up to 400°C. Please keep
continual attention to this tool. Keep sufficient distance to
combustible material. Use a heat resistant pad for this work.
•
This kit consist of small parts, which can be possibly swallowed
from children. Children (especially under 3 years) shall not
participate on the assembly without supervision.
Set-Up:
For the board assembly please follow exact the sequence of the
below
assembly list
. Cross each line off as
done
after
completing the insertion and the soldering of the respective part.
Please put the
clamps
together to a block with 17 connections
before assembling the clamps to the board.
Special attention is required for the t
antalum capacitor
. The leg
with the mark "+" has to be inserted to the respective marked
position on the pc-board.
Resistor-networks
are marked on one end with a printed circle
or a square. Assemble this component that way that the marking
corresponds with the marking between the first and second bore
on the pc-board. The first bore has been additionally marked with
a "1".
Please attend to the flat side of the
transistor.
Integrated circuits (IC`s)
are either marked with a half round
notch on one end or a printed point for the correct mounting
position. Push the IC`s into the correct socket assuring that the
notch or the printed point is corresponding to the half-rounded
marking on the pc-board.
Please attend to the sensitivity of the
ICs
to
electrostatic
discharge
, which will cause immediate damage of the IC. Before
touching those components please discharge yourself by
contacting an earthed metal (e.g. earthed radiator) or work with
an electrostatic safety pad.
Please
glue the two
labels
onto the
RJ-45 sockets
for
identification of the output socket
BU1
(cable in direction to the
central unit) and
BU2
(cable from next feedback unit).
