Safety
This section lists installation regulations that must be observed for safe operation of the prod-
uct.
2.1 General Safety Regulations
• This documentation is part of the product. Therefore, retain the documentation during
the entire service life of the product. Pass on the documentation to any subsequent
user of the product. In addition, ensure that any supplement to this documentation is
included, if necessary.
• The product must only be installed and put into operation by qualified electrical special-
ists 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
• High voltage can cause electric shock or burns! Disconnect all power supplies from the
products before performing any installation, repair or maintenance on the product.
• Make sure the product does not carry any voltage before starting work.
Power Supply
• For non-hazardous active voltage per EN/UL/IEC 61010-1, SELV/PELV power sup-
plies shall be used.
• Connecting impermissible current or frequency values may destroy the products.
Grounding/Protection/Fuses
• Establish sufficient grounding. Make sure there is a flawless electrical connection be-
tween the DIN-rail and frame / additional enclosure.
• When handling the product, please ensure that environmental factors (personnel, work
space and packaging) are properly equalized. Do not touch any conducting parts.
• In systems operated within the scope of UL, only use UL-approved fuses.
• Provide suitable disconnect and overcurrent protection on the system side. The protec-
tion device must be located near the product where it can be operated. The
OFF
posi-
tion must be clearly marked on the protection device.
• Without overcurrent protection, the electronics can be damaged. Provide appropriate
protection.
Cables
• To minimize interference (e.g., by electromagnetic interference), maintain a spatial
separation between control, signal and data lines and the power supply lines.
• The specified conductor cross-sections refer exclusively to the mechanical connection
capacity of the clamping points. Always use connecting cables designed for the maxi-
mum current load.
