Warning!
• Risk of electric shock. Switch off the power supply before opening the device. Do not install or
wire the device while it is connected to the power supply. Failure to comply with this precaution
can result in irreparable damage to the electronics.
• Risk of electric shock. Connect the protective earth to the ground terminal on the housing before
the power supply is applied (e.g. galvanically isolated power supply SELV or PELV).
• Compare the specifications on the nameplate with the local voltage supply and frequency. Also
observe the national regulations governing the installation of electrical equipment.
