Installation
All work (such as installation, electrical connection, startup, ope-
ration, and maintenance) must only be performed by sufficiently
qualified tradesmen. The respectively applicable local rules and
regulations (e.g. national building codes, electrical/VDE regula-
tions, etc.) must be observed. Installers and operating entities
are required to sufficiently familiarize themselves before startup.
Read the product description before operating the equipment.
Verify that the product can be used for the relevant application
without restrictions. We are not liable for printing errors and
changes after printing. Appropriate use implies compliance with
operating and installation instructions. We are not liable for losses
due to inappropriate use. Unauthorized or inappropriate mani-
pulations or modifications of the device render the operating
permit, the product warranty and warranty claims null and void.
