III - Power supply
There are two means of powering Profil 960 clocks:
1/ Power supply and synchronisation via Ethernet network (PoE). The circuit board is fitted with a
voltage converter to power the clock (A).
2/ Power via 230VAC 50/60Hz mains supply (B) and synchronisation via Ethernet network. (R)
A battery provides backup in case of loss of mains power (operating time: approximately 1 hour at
20°C, hands set to midday after 1 hour). When the clock is operating on battery power, illumination
and seconds display are automatically disabled.

- On power-up, the hands are positioned at midday until a time message is received. Once the NTP
synchronisation data is validated, the clock sets itself automatically to the time. This validation may
take a few minutes. In the absence of synchronisation the clock continues to operate on its base
time.
Time synchronisation uses an NTP server (3 possible modes):
- Address(es) provided by DHCP server
- Unicast NTP server (up to 5 separate addresses)
- Multicast server (1 address).
