WARNING
•
Use only PELV circuits as per IEC/DIN EN
60204-1 (Protective
PELV) for the electrical supply.
Consider also the general requirements for
PELV circuits in accordance with IEC/DIN EN
60204-1.
•
Use power supplies which guarantee reliable
electrical isolation of the operating voltage as
per IEC/DIN EN 60204-1.
By the use of PELV circuits, protection against
electric shock (protection against direct and indirect
contact) is guaranteed in accordance with IEC/EN
60204-1. (Electrical equipment for machines, Ge-
neral requirements).
CAUTION
The power supply to the outputs/valves (pin 2)
must be separately fused externally with max.
10 A. The external fuse prevents the valve ter-
minal from being damaged in the event of a
short circuit.
