1)
The external voltage supply must be capable of bridging a brief power failure of 20 ms as specified in
IEC 60204-1. Suitable power supply units are available as accessories from SICK.
Protect supply voltage against short-circuit.
2)
For use according to the requirements of ANSI/UL 508, ANSI/UL 60947-5-1 and ANSI/UL 60947-1,
voltage supply U
V
must be protected with 4 A and safety fuse gG.
3)
The power-up delay doubles with a new configuration.
