3.3 Electrical connections
• By authorized and qualified specialized personnel only.
• When connecting the unit, the national and international electro-technical
regulations must be observed.
• Disconnect the system from the mains, before electrically connecting the
device.
• Install the consumer-adapted fuses.
• Do not connect the connector if strained.
Only devices with contact elements are connected to the electrical supply. To
this end there is a cable socket on the side of the device, or a HAN plug in the
power plant version.
