WIRING OF CONTROL / SUMMARY
a) start with 230Volts supply cable.
Run cable through large cable bushing on the lefthand side.
b) Attach cable eye to ground wire. Then connect ground wire to
base plate with washer and nut (exactly as shown in picture detail).
Connect all other cables to control.
CABLES AND WIRING
The usage of shielded cable in order to connect the motor to control board is highly recommended. Magnetic and inductive influence of the signal in
the cables can produce electric noise and may disturb the function of the gate .
Generally avoid:
- Control board location far away from gate.
- 230Volt and low voltage in the same power line. Not allowed by electrical rules.
- Wiring of the infrared sensors, switches, flashing lamps & electric locks require a cable separately from the motor wiring.
- Other wirings like telephone intercoms, lights for garden etc. must be in separate cables.
- Rigid copper cables especially when thicker diameters are difficult to manage during the installation and may result in bad connections with
functional issues. Use instead flexible cables.
- Cable material not suitable for outside use. Use cables suitable for outside use and underground. Run the cables in conduits if the cable is not
suitable for placing in the ground (armoured or suitably protected). You may also consult your local electrician.
We recommend the following accessories:
- LA400-JB40E Kit for cable extension of one installation unit. Consists of 12m of cable 6-pole with identical colours, distribution box IP65,cable
screw joints and fastening material.
- 041ASWG-0482-50 Cable 50m for professional use. Consists of 50m of cable 6-pole with identical colours. Cut only as much as you need for the
current installation.
General wiring sizes:
The numbers mentioned in the table below are minimum requirements. It is always possible to use larger diameters.
- 230Volt Supply Power to controller: min. 0,75mm² 3-pole
- 230Volt Supply transformer installed separately (i.e. in the garage) and low voltage to gate. See table.
- Motor wiring: 2 wires min. 1,0mm², 4 wires min. 0,75mm² (or shielded cable)
- Electric locks: See table
- Switches, infrared sensors, flashing lamp: See table etc. min.0,5mm²
