When connecting a reed contact with a control input, the contact must
have a switching capacity of min. 1 A in order to prevent the contact
from sticking due to the inrush current. As an alternative, a suitable
resistor can be connected in series.
If one of the printer’s internal voltages '+5 VDC EXT' or '+24 VDC
EXT' is used, an external fuse e.g. 0.5 AF, should be additionally
installed to protect the printer electronics.
In the event of an inductive load, an antiparallel connected diode, for
instance, must be used to discharge the induction energy.
In order to minimise the influence of leakage currents at control
outputs, a resistor must, depending on what is connected, be installed
in parallel with the load.
In order to avoid any damages to the printing system, the max. output
currents must not be exceeded or outputs shorted.
