Electrical supply
During the electrical installation attention is to be paid to ensuring EN 60
204, part 1, point 6.3.3 "Protection by automatic interruption of the power
supply" is met.
On this topic also see IEC 364-4-41 (DIN 57 100, VDE 0100, part 410).
The machine is not allowed to be connected to mains with a residual
current circuit breaker, see EN 50178, point 5.3.2.3 (old VDE 0160, point
5.5.3.4.2).
As our machine has a leakage current higher than 3.5 mA AC due to EMC
measures, it must have a fixed connection.
In addition, one of the measures stated below must be taken, according to
EN 50178, point 5.3.2.1 (old VDE 0160, point 5.5.3.4.1 and 5.5.3.4.2).
•
Earth conductor cross section at least 25 mm² Cu.
•
Monitoring of the earth conductor by a device that will automatically
shut down the electronic equipment in the event of a fault.
•
Laying of a second conductor, electrically in parallel with the earth
conductor, using separate terminals. This conductor alone must comply
with the requirements of section 543 of the harmonisation document
(HD) 384.5.54 S1 (old DIN VDE 0100 part 540) for earth conductors.
The machine can be operated on a 400 V TN supply without a series
isolating transformer.
