Electric installation advice

In order to avoid outside interference, the user is advised to carry out the following points.
• Plug the Gravograph machine into a mains line, avoiding having several machines on the same line (several plugs on the same line or
using a multi-plug).
Exception :
• Avoid using the same line to supply inductive or capacitive machines as well as the Gravograph machine (motors, electrosluices,
chargers...).
• Avoid using a manual or automatic commutator on the same mains line as the Gravograph machine (relay, temporiser, programmer,
automatic circuit interrupter, automatic interrupter...).
• Check that machines surrounding your Gravograph machine are in conformity to the norms of radioelectric perturbation emissions (consult
the technical leaflet of each machine). If they are not in conformity, place them as far away as possible from the Gravograph machine.
• Only use Gravograph accessories (Gravograph relay box, etc ...).
