using a multi-plug).
Exception : If other things are connected to the machine (such as a computer and the I 4
machine), the machines should be connected to the same mains line.
• 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...).
• CheckthatmachinessurroundingyourGravographmachineareinconformitytothenormsofradioelectricperturbationemissions(consult
the technical leaflet of each machine). If they are not in conformity, place them as far away as possible from the Gravograph machine.
