• Perforate the relevant points in the bottom part of the box (Fig. 4.1).
• Fix the control panel permanently. You are advised to use round-head screws
(max head Ø 10mm) with a cross (hole centre distance indicated in Fig. 4.2 ).
• Insert the cable glands and corrugated tubes from the lower side of the container.
• Before connecting the power supply, make sure the plate data correspond to those of the
mains power supply.
• An omnipolar disconnection switch with a contact opening distance of at least 3mm must be
fitted on the mains supply.
• Check there is an adequate residual current circuit breaker and overcurrent cutout upstream
of the electrical system.
• For the power supply, use a H05RN-F 3G1.5 type electric cable. Connect it to the terminals L
(brown), N (blue),
(yellow/green) inside the automation (Fig. 4.3, page 8).
NOTE: the maximum permitted wire section is AWG14 (2mm²).
• In order to comply with the essential requisites of the Standards in force, reclose the cover
once the wires have been connected to the terminal.
• Make sure there are no sharp edges that may damage the cables.
• Make sure the mains supply wires (230V) and the wires of the accessories (24V) are separated.
• The cables must have dual insulation, be sheathed near the relative connection terminals,
and be held in place with ties [A] (not supplied).
• If necessary, fit the clip hinges on the bottom of the box and on the cover (left or right side, as
preferred) (Fig. 4.4, page 8).
After making the adjustments and settings, fix the cover in place with the screws supplied (Fig.
4.5, page 8).
The connections to the mains power supply and to any possible low voltage wires (230V)
in the section outside the control panel must be made on an independent channel sep-
arated from the connections to the command and safety devices (SELV= Safety Extra
Low Voltage). The corrugated tubes must enter the control panel by a few centimetres
via the holes on the base box.
