The installation of the power supply to connect our printers has to be
effected according to the international rules and regulations,
especially the recommendations of one of the three following
commissions:
International Electronic Commission (IEC)
European Committee for Electro technical Standardisation
(CENELEC)
Verband Deutscher Elektrotechniker (VDE)
Our printers are constructed according to VDE and have to be
connected to a grounded conductor. The power supply has to be
equipped with a grounded conductor to eliminate internal interfering
voltage.
Power line voltage and power line frequency: See type plate
Allowable tolerance of power line voltage:
+6% …
−
10% of nominal value
Allowable tolerance of power line frequency:
+2% …
−
2% of nominal value
Allowable distortion factor of power line voltage: <=5%
In case your net is infected (e.g. by using thyristor controlled
machines) anti-interference measures have to be taken. You can use
one of the following possibilities:
Provide separate power supply to our printers.
In case of problems please connect capacity-decoupled isolation
transformer or similar interference suppressor in front of our
printers.
