1.4.2 Safety - Electrical installation
Choose a location where to install the clock, preferably in a place free from electrical interferences,
such as transformers.
The clock must be powered by the electrical installation of the building.
It has been designed for category II overvoltages. Max. V peak: 2500V.
Provide a mains power supply protection compliant with IEC 61643 in other cases, if necessary.
The clock is connected to the Ethernet network. According to the model, power to control the hands
is supplied via the mains or the PoE Ethernet network. If available, the lighting is powered by the
mains.
The electrical installation of this equipment must comply with the electrical standards in force in the
country where the product is used. The installation must comply with the IEC 364 standard or with
the 802.3af, class 3 standard for PoE power supply. The IT network must be PoE or PoE+ for a clock
version with a PoE power supply.
Provide a differential circuit breaker max. 30mA / phase-neutral of 16A maximum,
rapidly accessible upstream of each power supply line (permanent power supply for the clock and
power supply for lighting depending on your model). This circuit breaker provides power supply pro-
tection and disconnection, and must be cut off in the event of maintenance.
Conductors on the same circuit must be attached to each other close to the terminal block to avoid
reduced isolation should one of the terminals become loose.
Attach the cables connected to the terminal block of the clock on the fixing plate (single-sided
model) or on the central bracket (double-sided model) with cable retainers to avoid pulling on the
terminal block.
Ethernet cable input (without RJ45 male plug) via cable gland with crimping of the male plug in the
single-sided clock.
Alarm relay circuit of max. 3A at 30V
The equipment should not be switched on until it has been mounted to the wall. The clock
must be closed.
Besides, with the lighting option, if the clock is open and switched on, there is a
danger of light radiation for the eyes.
Depending on the options chosen, your clock may be fitted with a backup battery.
There is a risk of explosion if the battery is replaced by a battery of incorrect type.
Dispose of used batteries according to the instructions.
