Avoid direct passage between operators as much as possible (to avoid electrostatic
induction and subsequent discharges);
If the electrical voltage supply differs from the required rating, this could seriously damage
the system;
Connection errors (and connections that differ from the prescribed ones) can pose a danger
to operator safety and cause faults in the system and to the instruments that are connected
to it;
Insert one or more easily accessible disconnecting devices to the exterior of the device to
separate the device from the power mains;
Do not use the device in environments with flammable gases.
Do not modify the device in any way.
