Basic safety notes
WARNING
Risk of lightning strikes
A lightning flash may enter the mains cables and data transmission cables and jump to a person.
Death, serious injury and burns can be caused by lightning.
Take the following precautions:
• Disconnect the device from the power supply in good time when a thunderstorm is
approaching.
• Do not touch mains cables and data transmission cables during a thunderstorm.
• Keep an enough distance from electric cables, distributors, systems, etc.
CAUTION
Use copper cables at connectors with terminal connections
Use copper (Cu) cables for all supply lines that are connected to the device with terminals, e.g.
24 V DC power supply cables to the 24 V DC power supply connectors.
Utiliser des câbles en cuivre sur les connexions à bornes
Utilisez des câbles en cuivre (Cu) pour tous les câbles d'alimentation qui sont raccordés à
l'appareil par des bornes, par exemple les câbles d'alimentation 24 V CC sur le connecteur
d'alimentation 24 V CC.
Note
The device should only be connected to a 24 V DC power supply which meets the requirements
of safe extra low voltage (SELV) according to IEC/EN/DIN EN/UL 61010-1.
Note
The power supply must be adapted to the input data of the device. See chapter "Technical
specifications SITRANS CC220 (Page 69)".
If there are voltage peaks on power supply lines, use a protective device in the form of a varistor
(MOV) UMOV = U-rated x 1.2 (BLITZDUCTOR BVT AVD 24 (918 422) or compatible).
