3.2 Mains connection
3.2.1
General important advice
Please read the following important advice carefully before starting with the assembly works:
The mains connection must only be made by electrically certified and trained personnel!
All assembly works have to be executed without operating and battery voltage!
Discharge yourself before the beginning of the assembly works by touching earthed metal parts to avoid
damages at semiconductor devices by electrostatic discharge (ESD)!
All power supply units may only be connected with a protective conductor connection (PE)!
The mains cable has to be secured at the terminal clamps by a strain relief!
All in the system housing incoming reporting cables have to be earthed via the housing!
Disconnect device : a disconnect device including a 5A protection should be installed in the electrical cabi-
net in order to disconnect the equipment from the mains supply (e.g. for maintenance purpose…). Please
note that this disconnect device should have a contact separation of at least 3mm, and provide with differn-
tiel protection of 30mA.
