III.1 Power supply
The switching power supply works normally with
230V 50/60Hz but it can works also with 115V.
Nota : the 230V/115V input voltage switch is located
under the switching power supply. To access the switch, dismantle the digit in front of
the switching power supply, unscrew the HM8 screw and remove the fixing plate. Push
the switch to 115VAC and fit everything together again.
Connect the mains supply to the switching power supply (D) located behind the
protection glass of the clock.
Nota 1 : remove the protection glass to access to the switching power supply (see §
II.1).
Nota 2 : The adhesive protection that has been supplied must be put above the
switching power supply terminals when cabling is completed. It prevents from any direct
contact with dangerous voltage.
III.2 France Inter / DCF antenna
When connected to a FI or DCF antenna, the clock is set automatically to the
right time. However, it is still possible to set the clock manually following the
instructions given page 24.
In case of difficult reception, the signal acquisition can last many hours (The
signal is usually well received during the night).
Connect the antenna on the terminal (C) of the electronic card. There is no
polarity to be respected.
For a better reception, put the antenna outside the
clock.
III.3 GPS antenna
To get high precision worldwide, it is possible to connect a GPS
antenna to the clock.
The clock is delivered with the GPS antenna fixed inside.
Ensure that the GPS antenna is properly connected to the
terminal (A) of the electronic card. There is no polarity to be
respected.
Note: synchronisation of the GPS antenna can only be carried out
with a clock installed outdoors. Otherwise, the antenna will have to be
placed outside the building in an unobstructed area.
