5 Installation
Before proceeding with installation, it is necessary to:
• Check that the point of attachment of the control panel is protected from shocks, the fastening surfaces are solid, and appro-
priate components (screws, plugs, etc) are used for fastening to the surface.
• Provide for an appropriate omni-polar disconnection device with a distance of more than 3 mm between the contacts, to
shunt the power supply
•
Check that the connections inside the case executed for continuity of the protection circuit are allowed, provided they have
supplementary isolation with respect to the other internal conducting parts.
• Prepare adequate cable troughs and hoses for the electrical wires, to ensure protection against mechanical damage.
5.2 Equipment and materials
