GENERAL WARNINGS
The characteristics of the electrical lines and relevant components must be determined by specialized personnel able to
design electrical installations; moreover, the lines must be in conformity with professional procedures and the regulations
in force.
All electrical operations should be performed by trained personnel having the necessary requisites under law and being
informed about the risks relevant to these activities.
Bifore performing any operation on the electrical system, make sure that the unit supply line is SELECTED AT START.
For all electrical type operations, refer to the electrical diagram attached to the unit; the number of the diagram is shown
on the registration plate positioned on the electrical board or next to it.
The electrical diagram should be carefully kept together with this manual and should be available for future intervention
on the unit.
LINE OF UNIT POWER SUPPLY
The electrical data of the unit are shown in the technical chart of this manual and on the unit registration plate.
The presence of accessories can vary according to the unit; the electrical data shown in the technical chart refer to
standard units. In the event of differences between the data of the registration plate and the data shown in this manual,
as well as in the technical chart, please refer to the data shown in the registration plate.
The protection device of the unit power supply line should break off the short circuit power whose value should be
determined according to the plant features.
The section of supply cables and protection cable must be seized according to the characteristics of the protections
used.
SIGNALS / DATA LINES
Do not exceed the MAXIMUM ALLOWED DISTANCE, that varies according to the type of signal.
Observe the requisites relevant to IMPEDANCE, CAPACITY, ATTENUATION (where necessary).
Follow the indication relevant to SHIELDING (where necessary).
Place the cables FAR FROM POWER CABLES or cables that have a different tension or emit electromagnetic
disturbances.
AVOID LAYING CABLES IN PARALLEL TO OTHER CONDUCTORS AS WELL AS INSIDE THE SAME RACEWAY.
