Electrical Connections; Connection Description - Nice DPRO924 Instructions And Warnings For Installation And Use

D: FLASHER cable with aerial
E: PHOTOCELL cable
F: KEY SWITCH cable
G: COILED cable for sensitive edge
Note 1 – If the power cable exceeds 30 m in length, a cable with a larger section (3 x 2.5 mm
be installed.
Note 2 – These 2 cables can be replaced with just one 4 x 0.5 mm
CAUTION! – The cables used must be suitable to the type of room where the unit is installed.

ELECTRICAL CONNECTIONS

CAUTION!
– Before you proceed to make any electrical connections make sure that the power supply is disconnected;
– Connections must only be carried out by qualified personnel.
– You must put a device on the electricity supply line that ensures complete disconnection of the automated mechanism from the mains supply. The discon-
nection device must have contacts with an opening distance large enough to permit complete disconnection under the conditions sanctioned by overvoltage
category III, in accordance with installation regulations. The device ensures quick, safe disconnection from the power supply if needed, and must therefore
be in a position that is visible from the automation mechanism. If, on the other hand, it is located in a position which is not visible, there must be a system for
preventing accidental or unauthorised reconnection to the mains supply to prevent this risk. The disconnection device is not supplied with the product.

3.1 - Connection description

Find below the description of the meaning of the marks printed on the electronic board at the relative terminals:
PUSH BUTTONS
Input for the connections of the buttons on the box lid
Input for the connection of the transformer power
24V Ground
Battery (symbol) Connector for the connection of the buffer battery mod. PS224
Incremental encoder Terminal for the connection of the encoder of the Sumo- family motors - No polarity to comply with
Motor
Terminal for the connection of the electrical motor and the ground
Attention to polarity: connect the motor so that, when the opening command is given, the opening of the door matches it on the
control unit
1: 24V
2: 24V
3: motor
Limit Switch Connector for the electromechanical limit switch connection:
(function unavailable)
Common: limit switch common
Open: input of maximum opening limit switch
Preclose: input of the preclosing limit switch, adjusted at about 3 cm above the closing limit switch. The detection of obstacles, or
sensitive edge, between the closing and pre-closing position, stops the closing movement and the control unit considers the door in
completely-closed position.
Open: input of maximum closing limit switch
IBT4N
Input for the connection of the Oview programmer, with the appropriate IBT4N adapter.
CAUTION! - Disconnect the power before connecting/disconnecting the programmer.
Input for the connection of the radio receiver aerial (note: in Nice flashers Mod. ELDC, the aerial is built-in)
Aerial
STOP Input for the connection of resistive-type sensitive edges (8k2) or optical ones (OSE), as described below (fig. 5):
OSE connection:
- positive 12V
- signal (S) (green wires)
- negative GND (-) (white wires)
Connection 8k2:
- Connect the 8.2 kΩ resistance between the Signal and GND terminals
