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 ground to the ground terminal on the
housing before the power supply is applied (not required for galvanically isolated power
supply).
• Compare the specifications on the nameplate with the local supply voltage and frequency.
The national regulations governing the installation of electrical equipment also apply.
