14 Installation and assembly
14.1 Machine layout, connection points and working
dimensions
For the layouts showing the positioning of the machines, their working dimensions, and the
connection points for the supply lines, refer to chapter 12.1 “Layout”
14.2 Installation area requisites
The essential requisites for the various systems which the machine will be connected to are
described below, along with those for the room in which it will be set up.
Electric system requisites
The quality of the electric system must guarantee the essential requisites indicated in the EN
60204-1 standards, unless otherwise agreed with the customer.
Supply voltage: see the rating plate
Supply voltage frequency: see the rating plate
Maximum input power: see the rating plate
No differential type protection is foreseen for the machine’s electric system. The choice of
differential protection must not contrast with current legal requirements, local regulations, or the
characteristics of the factory and machine electrical system.
Bear in mind the following machine characteristics to ensure you make the correct choice:
1. Electromagnetic disturbance limitation measures (mains filter and screening) may produce
high frequency leakage currents and pulse leakage currents exceeding 30 mA.
The 30 mA differential switches may not guarantee continuous operation under all conditions.
2. The machine may be subject to earth faults even with direct current (IEC 755).
If this is not in contrast with local laws or the characteristics of the system, you are advised to
fit differential switches with adjustable currents and trip times, of the type that are not
influenced by high frequencies.
You are advised to use differential switches that will easily withstand pulse type overvoltage of
atmospheric and switching origin (class B).
It is not advisable to use differential switches of class AC.
