USE AND MAINTENANCE MANUAL - ELECTRICAL EQUIPMENT
Below are the specific technical data and specifications for each coded type of electrical equipment supplied: this
data is shown on the identification plate affixed to the external and internal side of the door of the control panel.

The impedance of the fault loop refers to the power source (including the impedance of the protection
circuit) from the terminals of the disconnecting device of the electrical equipment: the user is advised to consider the
increase in resistance of the supply line conductors due to the fault current, when evaluating the impedance of the
power source.
If the impedance of the fault loop of the power source exceeds the "reference impedance test" value, it is
recommended to verify the characteristics of the supply protection circuit, once installation is complete and
before commissioning takes place, in accordance with "Test 2" testing method (refer to CEI EN 60204-1 para.
18.2).
If the prospective short-circuit current at insertion point of the equipment should exceed that
indicated in the specific technical data, a device must be installed so as to limit the current
below this value.
The user must comply with the technical specifications of the equipment so as not to damage it
or put personnel at risk!
The equipment is protected with the required earthing system should the impedance of the fault
loop of the power source be lower than the value indicated in the specific technical data. The
user must adopt additional protection measures upstream the electrical equipment supplied if
the earthing system differs from than prescribed or impedance of the fault loop exceeds that
which is specified.
The values of the impedance of the fault loop indicated in the specific technical data only refer
to electrical control panels supplied fully wired to the relative machine. If loose panels are
supplied that are not wired to the machine, always contact Varisco SpA before installation.

The control functions and use of the equipment must be implemented within the limits indicated in the previous
paragraph, "GENERAL TECHNICAL DATA" - in well-ventilated and well-lit environments, with no hazardous
reflections, so as to ensure the equipment is ventilated appropriately and each part is clearly visible, the control
panel is clearly read and the actuators are identified, in particular that which stops the equipment in an emergency.
Any other use is to be considered unintended and prohibited as this can cause unforeseen personal risks of
an electrical nature and/or other type and damage the equipment or production.
Only appropriate fire extinguishers (e.g. carbon dioxide) are to be used in case of fire or any
other situation where open flames appear inside or outside the equipment. It is strictly
prohibited to use water to put out the flames!

The following are considered misuse and are therefore prohibited:
using the equipment differently than that indicated in the previous point;
using the equipment in potentially explosive environments due to the presence of gases, vapours or dusts;
using the equipment in a harsh environment or in the presence of high concentration of dust or oily
substances suspended in the air;
