2 Installation
the connection to the 110/230 V AC power network can only be done by authorized personnel
with appropriate qualification and training;
connect the cables always in unpowered state – otherwise the risk of electric shock exist;
producer is not responsible for breakdowns caused by unsuitable clock mounting on the
bearing surface;
2.1 Single-sided clock up to DSC.320
assemble the wall mounting console if delivered disassembled;
drill at least four anchoring holes into the wall, of a diameter adequate to
appropriate screws, use the mounting console as a template;
mount the console on the wall and put it into a fully tilted out position;
shift the clock body into the flipped out console arms and fix it by tightening the
screws;
dismantle the back cover of connectors on the clock body; the cover incorporates
gap with sealings for passage of cables in the inside of he clock;
arrange all cables to appropriate length and connect them to the appropriate
terminals on the PCB; see the description of the connectors and observe the
correct polarity where necessary;
fix the cables with the holder in correct positions in order to maintain regular
spacing between the cables in the area of passing through sealing; use
appropriate force to not to damage the cables insulation;
configure the Line type jumper according to used synchronisation signal (applies
only for DCF, MOBALine, Serial MOBATIME code, polarized impulse line or
IRIG-B);
mount back the connector cover;
tilt the clock into vertical position and fix the position of the console;
2.2 Single-sided clock DSC.500

the back side of the clock part;
hang the MASTER part on second side of the console and tighten the four
screws on the back side of the clock part;
connect the MASTER-SLAVE cable;
arrange all incoming cables to appropriate length and connect them to the
appropriate terminals on the PCB; see the description of the connectors and
observe the correct polarity where necessary;
fix the cables with the holder in correct positions in order to maintain regular
spacing between the cables in the area of passing through sealing; use
appropriate force to not to damage the cables insulation;
configure the Line type jumper according to used synchronisation signal (applies
only for DCF, MOBALine, Serial MOBATIME code, polarized impulse line or
IRIG-B);
