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 (not necessary if the power supply is
galvanically isolated).
• Compare the specifications on the nameplate with the local supply voltage and
frequency. The national regulations governing the installation of electrical equipment
also apply.
• Promag 10 has to be connected to switched/protected circuits of the installation.
