2 Safety

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 sources from the
product before performing any installation, repair or maintenance.
• 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 product.
• 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.
Cables
• Always design the connection cables for the maximum anticipated current load.
• High currents and the inherent head generated by the product can cause additional
heat generation at the clamping point. Plan for a correspondingly higher temperature
range for the connecting cables, or reduce inherent heat by selecting larger conductor
cross-sections.
• Only one conductor may be connected to each connection point (e.g., CAGE CLAMP
connection).
Grounding/Protection/Fuses
• When handling the product, please ensure that environmental factors (personnel, work
space and packaging) are properly equalized. Do not touch any conducting parts.

2.3 Mechanical Safety

• Before startup, please check the product for any damage that may have occurred dur-
ing shipping. Do not put the product into operation in the event of mechanical damage.
• Do not open the product housing.
• Avoid conductive contamination.
