2.1.2 Electrical installation
There are two versions of NTP clock: PoE or 230V
.
Read the product label to determine your version.
The lighting (if this option has been selected) is always powered via a mains power supply.
However, power supply for the circuit board may vary according to your model:
NTP PoE model: power supply of the board is provided via the Ethernet cable.
NTP 230V
model: power supply of the board is provided via a second power supply (15V)
connected to the mains.
2.1.2.1 Electrical installation - NTP 230V model
Where the lighting is controlled by the clock, a single mains cable is enough.
It is possible to create an electrical bridge as per illustration A.
Where the lighting is controlled by another line, two mains cables are required
(case described below).
- With lighting option: pass the first mains cable through the left-hand cable gland then connect
this cable to the terminal block
in the terminals L-N-
dedicated to the lighting
,
1
- Pass the second mains cable through the right-hand cable gland then connect this cable to the
terminal block
1
in the terminals L-N-
dedicated to the circuit board
,
(Both mains cables must come from the same building)
- Attach these cables to the fixing plate with cable retainers
,
- Pass the Ethernet cable through the smallest central cable gland,
- Then crimp the RJ45 male connector on the cable, but only once it has been passed through into
the clock and check crimping of the cable using a network tester,
2
- Then connect this cable to the circuit board via the Ethernet port
,
3
- Connect the back-up battery cable (if there is one) to the circuit board
,
- Clean the seal and then apply silicone oil on it,

- Move the clock face closer and then reconnect the flat cable
that goes from the circuit
board to the movement
located on the clock face,
5
- Limit the length of the cable by passing it through the cable clip
in order to avoid shading in
6
the case of the lighting option (contact of the cable with the dial once the clock is closed),
- Close the clock again by putting the clock face back in its original position,
- Tighten the four cover screws (1,2 Nm),
- Replace and tighten the air inlet screw (15 Nm) located on the underside of the clock.
