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.
3.1 - Connecting the three-phase power supply cable for
NDCC2000 and NDCC2100 control units
To make the electrical connection refer to
Fig. 5
.
A 16A EEC plug is connected to terminals L1, L2 and L3 and to the PE ter
-
minal.
The control unit can also be connected using a three-phase main switch
(accessory not supplied). In this case, you can remove the EEC plug during
assembly.
3.2 - Connecting the single-phase power supply cable for
NDCC2200 control units
To make the electrical connection refer to
Fig. 6
.
A Schuko plug is connected to terminals L1 and L3 and to the PE terminal.
The control unit can also be connected using a single-phase main switch
(accessory not supplied). In this case, you can remove the Schuko plug during
assembly.
3.3 - Description of the electrical connections (Fig. 7): 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).
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 D-Action.
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) Common limit switch
(2) LS opens
(3) pre-limit switch closes
(4) LS closes
STOP
- Input for connecting resistive sensitive edges (8k2) or optical sensi
-
tive edges (OSE), as described below (
Fig. 9
):
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)
IBT4N
- Input for connecting the Oview programmer, with the IBT4N adapt
-
er. CAUTION - disconnect the power supply before connecting/disconnect
-
ing the programmer.
ANTENNA
- Input for connecting the radio receiver aerial (Note: the
aerial is built into the Nice LUCY B, MBL and MLBT flashing lights).
OUT (CONNECTOR FOR NDA040)
- Connector for NDA040 accessory
card that adds two outputs to voltage-free contacts. These outputs can be
properly programmed with the Nice Oview programmer. For a description
and instructions on programming the available functions, see the NDA040
accessory board manual.
SLOT FOR BRAKE/BOOST BOARD
- Connector for connecting the ad-
ditional board for the motor brake (BRAKE) and starting capacitor (BOOST)
control functions for single-phase motors. ATTENTION - not included with
the NDCC2000 model.
MOTOR
- Output for connecting the single-phase and three-phase motor.
For single-phase motors:
U - common
V - opens
W - closes
LINE
- Input for connecting the power supply.
L1-L2-L3: THREE-PHASE connection
L1-L3: SINGLE-PHASE connection
PE
- Input for the earth connection for the control unit and motors.
IMPORTANT!
We DO NOT recommend that you connect
any device or accessory not mentioned in this
instruction manual.
The manufacturer declines all responsibility
whatsoever for any damage due to improper
use of the various system devices that does not
comply with the instructions in this manual.
For more information, please contact the Nice
Customer Service.
