Safety Instructions
These safety instructions must be followed throughout the whole installation process:
• Remove your jewellery (including bracelets and chains) during installation.
• When drilling and soldering, wear special goggles and appropriate protection.
• Use appropriate tools, as specified on page 2.
• Handle the motorisation system with caution to avoid injury.
• Do not connect the motor to the mains or the (optional) backup battery until the
mounting process has been completed.
• Never use a high-pressure water flow rate for cleaning.

Electrical pre-wiring
To motorise your gate:
• Install a 230 V electric supply on one of the gateposts, as near as possible to the SGA
motor.
• Interconnect the gateposts using the 2 x 1 mm
2
cable provided (or two cables for
photocells).
Use a 25-mm-diameter Orange ICT protective sheath for burying the cables.
If you cannot dig a cable trench between the two gateposts, use a raceway that will bear the
weight of vehicles passing over it (ref. 2400484).
• Provide a ducted connection between the two gateposts to wire the photocells.

Mains power
To operate, the gate opener must be powered at 230 V, 50 Hz.
The electrical wire must be:
• Used only for the gate opener.
• Protected:
- by a 10-A fuse or circuit breaker,
- by a differential device (30 mA).
• Installed in compliance with electrical safety standards in force locally.
An all-pole power disconnection means must be provided:
• either a supply cable with an electrical plug;
• or a switch which keeps the contacts at least 3 mm apart at each pole (see standard EN
60335-1).
It is recommended to install a lightning arrestor (with a maximum residual voltage of 2 kV).
●
Photocells
(supplied with SGA 5000)
The photocells are necessary for automatic-mode operation and for gates opening onto the
public highway.
• Wiring the photocells (see page 32)
The 24-V input and information received from the contacts (receiving cell) must be under
the cells.
Drill the gateposts to pass the ducts through them.
