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
disconnection 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 mecha-
nism. 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 sup-
plied with the product.
– Selecting the power supply voltage:
The control unit can function correctly with three-phase or single-phase
power (see wiring diagrams), with either 400 V or 230 V voltage.
The default setting is three-phase 400 V power supply voltage.
To select the 230 V single-phase power supply, observe the instructions
specified in Chapter 7.2

7.1 - Connecting the three-phase power supply cable

To make the electrical connection refer to Fig. 11.
A 16 A CEE plug must be connected to terminals L1, L2 and L3 and to the
PE terminal.

7.2 - Connecting the single-phase power supply cable

To make the electrical connection refer to Fig. 12.
A Schuko plug must be connected to terminals L1 and L3 and to the PE
terminal.

7.3 - Changing the power supply through the jumper

The power supply to the control unit can be changed through the jumper, as
explained below (Fig. 13)
01. Remove the top cover
02. Extract the jumper (default position 3 x 400 V) using needle-nose pliers
03. Insert the jumper (1 x 230 V)
04. Re-insert the top cover
7.4 - Description of the electrical connections (Fig. 14): power
supply, safety and control devices and accessories
You can connect control devices with "Normally Open" (NO) or "Normally
Closed" (NC) contacts to the 8, 9, 10 and 11 inputs. You can then make use of
one of these inputs or a combination thereof, as well as the STOP/ALT inputs if

appropriate, to connect an external push button panel, for example, or a switch
with a rope connected to the ceiling.
PUSH BUTTONS - Input for connecting the push button panel on the cover
of the box.
ENCODER - Input for connecting the wiring of the electronic limit switch
(Nice encoder). Not usable in this version.
COMMON (8) - 24 V DC input that acts as a common input for the OPEN,
CLOSE and ING1 inputs and positive for power supply to the services.
OPEN (9) - Input for devices which control only the opening movement. It is
possible to connect contacts of the "Normally Open" type to this input.
CLOSE (10) - Input for devices which control only the closing movement.
It is possible to connect contacts of the "Normally Open" type to this input.
ING1-photo- (11) - Normally Closed (NC) input for devices that control the
movement of the automation. If this input is properly programmed with the
Nice Oview programmer, you can get the following operating modes:
– Step-by-step
– Partial Open
– Open
– Close
– Photo (default)
– Photo 1
– Alt in opening
– Alt in closing
For a description and instructions on how to program the available functions,
refer to the Oview function sheets for DPRO500.
ALT - Input for devices that stop a manoeuvre when in progress; connect
contacts of the "Normally Closed" type.
SAFE - Input for connecting the thermal protection device of the motor.
CAUTION! - It is only used for motors with mechanical limit switches. Leave
"unconnected" with motors which have electronic limit switches.
LIMIT SWITCH - Input for connecting mechanical limit switches.
(1) limit switch common
(2) limit switch open
(3) pre-limit switch close
(4) limit switch close
STOP - Input for connecting resistive sensitive edges (8k2) or optical sensi-
tive edges (OSE), as described below (Fig. 15):
OSE Connection:
- 5 Ò positive 12 V DC (+) (brown wires)
- 6 Ò signal (S) (green wires)
- 7 Ò GND negative (-) (white wires)
8k2 Connection:
- Connect the 8.2 kΩ resistor between terminals 6 (signal - S) and 7 (nega-
tive - GND)
