MESH FILTER
In order to meet the standards of directives concerning electromagnetic compatibility, it may be necessary to provide the machine with a mesh
filter outside the card.
In this case, its installation requires compliance with a few basic rules:
• the filter (if of a type with a metallic body) must be installed on the metal frame of the unit, with an electrical path of low impedance
towards earth.
• It must be installed as near as possible to the entry point of the of the power cable, with short input and output connections that are set
well apart from each other, to avoid disturbances between the mains, loads and the unit.
If the filter is not installed in compliance these instructions, it may lose all or part of its effectiveness.
PERFORMANCE
Best performance of the card is obtained at an ambient temperature of roughly 25°C.
For higher or lower temperatures, precision and heat dissipation results tend to worsen.
However, the temperature range as defined in the electrical characteristics is adhered to.
To avoid permanent damage to some components, remain within the range 0...70°C.
13. WARNINGS
DANGER
The unit contains parts with a high voltage power supply.
Before performing any work, disconnect the unit from the electrical mains.
START-UP
Before providing power to the unit, make all required connections.
PROTECTION
Ensure that all accessible metal parts which may receive live current due to an insulation defect are permanently and securely attached to the
earth terminal of the machine.
Ensure that the earth terminal of the machine is connected to an efficient earth protection
EXTERNAL COMPONENTS
The insertion of components outside the card which are required to ensure suitable reduction of disturbances must not compromise the safety
of the unit. This means that they must be of a suitable type and value.
COMPONENTS
If necessary, we reserve the right to replace the components used with other devices produced by other manufacturers but
with the same electrical and regulatory characteristics.
SOFTWARE
If necessary, we reserve the right to make partial corrections to the described procedures during the software development stage, to allow easier
or more effective use of the machine or a more coherent development of software, without modifying the functional aspects of the machine.
SAFETY
Protection against electrical shock, fire hazard, mechanical risks or hazardous malfunctions in other parts of the machine does not depend on
correct operation of the electronic circuit.
Therefore, where necessary, the machine must be equipped with safety devices which are independent of the electronic circuit (e.g. pressure
overload safety valve).
