Danger to life by switching medical devices
Unintentional switching of medical devices can result in life-threatening situations.
• Do not connect any medical devices to the switching device (e.g. radio-controlled socket/relay).
Risk of injury and fire due to unintentional and unattended switching on of loads
Loads that are switched on via a radio-controlled socket or a relay unintentionally and while unattended can cause
injuries and fires (e.g. an iron).
• Do not connect any loads to the switching device that could endanger persons or cause damage if
unintentionally switched on.
Damage to loads due through frequent switching
Frequently switching a load on and off can damage it.
• Ask the load manufacturer whether the load is suitable for control via a radio-controlled socket or relay, for
example.
• Configure the switching device so that the load connected is not switched on or off more frequently than
specified by the load manufacturer.
• Do not connect any loads to the switching device if they require a continuous current supply.
DHCP Server is recommended
The DCHP server automatically assigns the appropriate network settings to your nodes in the local network. A
manual network configuration is therefore not necessary. In a local network, the Internet router is usually the
DHCP server. If the IP addresses in the local network are to be assigned dynamically, DHCP must be activated in
the Internet router (see the Internet router manual). In order to receive the same IP address by the internet router
after a restart, set the MAC address binding.
In networks where no DHCP server is active, proper IP addresses must be assigned from the free address pool of
the network segment to all network participants to be integrated during commissioning.
