Connection

Dangerous electrical voltage leads to electric shock and arc flashover!

Non-compliance will result in death, personal injury or considerable material damage!
Ensure a safe working environment during assembly, maintenance and installation work

• Before beginning any assembly, maintenance, or installation work, disconnect the system from the power supply!
• Interrupt the power supply of the primary conductor and secure against being switched on again inadvertently.
• Make sure that the details on the nameplate and in the “Technical data” correspond to the operating parameters of the system.

Power supply from SELV / PELV power supply unit!

SELV / PELV circuits (safety extra-low voltage / protective extra-low voltage) according to IEC 61010-2-201 must be used to supply this device.

Notes:

• SELV / PELV circuits may give rise to further requirements from standards such as IEC 60204-1 et al, for example with regard to cable spacing and insulation.
• A SELV supply provides safe electrical isolation and limitation of the voltage without a connection to the protective conductor, a PELV supply also requires a safe connection to the protective conductor.
