Making the stationary mains connection
7.3.2 Heed network prerequisites
With regard to the stationary mains connection, make sure that:
• This may only be done in Germany by an installation company that is
registered in the installers' directory of the local power supply company.
• In Europe, this must generally be done by an electrically qualified per-
son.
This electrically qualified person must be familiar with the correspond-
ing standards, especially EN IEC 60364, as well as the technical con-
nection requirements of the local power supply company.
• This may not be connected by an MBO technician or a customer ser-
vice technician.
• For the electrical installation, EN 60204-1, Clause 6.3.3. "Protection
through automatic switching off of the supply" is adhered to.
• The loop impedance and the suitability of the assigned overcurrent pro-
tection device are checked according to EN 60204-1, Clause 18.2.2.
• A TN-S power system or TN-C-S power system is mandatory as the
power supply system.
• The voltage, frequency, network cross-section, and mains protection
must match the details on the name plate, wiring diagram, and "Speci-
fications" of the operating manual.
• Due to the leakage currents of the EMC filter, the mains connection
must be stationary.
• Due to the leakage currents of the EMC filter, no power supply with a
ground fault circuit interrupter (GFCI) or a voltage fluctuation relay can
be used.
• Due to the leakage currents of the EMC filter, a protective equipotential
bonding system according to EN 60204-1, Clause 8.2.8 must be con-
nected.
• The customer's grounding system should have as small a grounding re-
sistance as possible (optimal would be a value < 2 Ohm), since with rel-
atively high grounding resistance levels (> 50 Ohm) the EMC filters
hardly have any more filter effect.
• The N conductor is loaded (for 400 VAC power supply).
• A right rotating field is absolutely necessary.
CAUTION!
Incorrect supply voltage.
Non-observance could result in property damage.
• Verify that the specifications for mains voltage and frequency on the
name plate match the supply network data.
• Connect the machine only if the mains voltage and frequency
match.
• If the existing rated voltage deviates from the details on the name
plate, wiring diagram, and "technical data" in the operating manual,
an isolating transformer must be used.
You can get the necessary information from the manufacturer.
