II - Installation
2.1 Pre-requisit
Choose a location where to install the clock, preferably away from sources of electrical interference,
such as transformers.
Installation and maintenance of this equipment must be carried out by qualified personnel.
The clock is connected to the mains power supply or to the Ethernet (PoE) data network. The
equipment must be installed in compliance with standard IEC 364 (NFC 15-100 for France) or
802.3af, class 3 where powered by PoE.
The clock must be powered by the building's electrical supply. It is designed for category II
overvoltages. Vpeak maximum: 250V. In other cases, mains power protection compliant with CEI
61643 should be provided if necessary.
These clocks must remain powered all the time. If it is necessary to switch off the illumination during
daytime, use the internal command relay provided (A).
Note: An easily-accessible circuit breaker or fuse disconnect switch with maximum rating of 5A
should be provided for the permanent mains power connection and illumination. The circuit breaker/
fused switch must cut the phase and neutral simultaneously. These cut-off devices must be clearly
identified. In the case of maintenance, cut off the mains connection and the illumination.
Alarm relay circuit maximum 3A at 30V AC/DC.
Ethernet cable entry via CM10P cable gland, with connector crimped inside clock.
Conductors on a single circuit must be attached together close to the terminal block to avoid reduced
insulation in the case of one of the terminals coming unscrewed.
NOTE: RISK OF EXPLOSION IF THE BATTERY IS REPLACED BY A BATTERY
OF INCORRECT TYPE. DISCARD USED BATTERIES IN ACCORDANCE WITH
INSTRUCTIONS.
