2.1 General Safety Regulations
• This documentation is part of the Products. Retain the documentation for the entire
service life of the Products. Pass on the documentation to any subsequent user of the
Products. In addition, ensure that any supplement to this documentation is included, if
necessary.
• The Products must only be installed and put into operation by qualified electrical spe-
cialists per EN 50110-1/-2 and IEC 60364.
• Comply with the laws, standards, guidelines, local regulations and accepted technol-
ogy standards and practices applicable at the time of installation.
2.2 Electrical Safety
• Make sure the products do not carry any voltage before starting work.
Power supply
• Use safe extra-low voltage with separation (SELV, PELV) for all voltages with a nomi-
nal value of 24 VDC.
• When configuring the system, make sure that the maximum total current of the field
supply of the node is not exceeded. Where needed, include an additional supply mod-
ule.
• When configuring the system, make sure that the maximum total current of the system
supply of the node is not exceeded. Where needed, include an additional supply mod-
ule.
• Connecting impermissible current or frequency values may destroy the products.
• Plan for voltage buffering if the requirement for voltage buffering according to EN
61131-2 is to be met.
• Take suitable measures to protect against overload (e.g., a supply module with fuse or
an external fuse).
• In mixed operation, always separate the areas in the XTR version and the areas with
the standard version with the separate potential supply modules for the field supply
and separate power supply units of the respective version in different potential groups.
Do not mix the versions within these potential groups.
Grounding/Protection/Fuses
• Establish sufficient grounding. Make sure there is a flawless electrical connection be-
tween the DIN-rail and frame / additional enclosure.
• For UL-approved systems, use fuses with UL approval only .
Cables
• Maintain spacing between control, signal and data lines and the power supply lines.
• Observe permissible temperature range of connecting cables.
• You must only connect one conductor to each clamping unit.
