How To Install The Camera Power Supply - Videotec HEA26 Manuel D'instructions

Carry out the connections of the circuit to the
external source of power.
The dustproof housings are pre-arranged for fixing
possible ground connections to be carried out in
compliance with the legislation in force.

6.1.5 How to install the camera power
supply
This chapter describes how to install the camera
power supply option into the housing. The camera
power supply has an input voltage of 115/230Vac
and an output voltage, depending on the model, of
12Vdc/24Vac, 400mA. Remember that the camera
power supply option can only be assembled together
with the fan if the latter uses a voltage of 12Vdc (with
12Vdc camera power supply).
Remove the body by loosing the two screws at the
bottom rear of the housing.
If heating is installed, loosen the screws of the circuit
terminal board, disconnect the wires and remove
the circuit in question by unscrewing the two self-
tapping screws.
Apply the plastic spacer onto the slide turret (01).
Replace the earth wire between the circuit and the
slide with the wire supplied with the optional device,
if it is the case, apply the plastic protection to the
terminal wire that will eventually be fixed onto the
slide (02).
Apply the plastic protection to the terminal wire of
the earthing connected in part to the body of the
housing and in part to the internal slide. If necessary,
bend the fastons to ensure their adherence to the
internal slide.
IN 230Vac
Fix the camera power supply circuit in the available
position of the internal slide in the bottom rear of the
housing (03).

Connect the camera power supply wires of the
camera checking their voltage on the output boards,
marked 12Vdc/24Vac.
If fitted, connect the heating wires into the terminal
block marked HEATER.
Connect the mains wires to the input terminal block.
