CAUTION
Protection of the 24VAC Supply Voltage
Transformers must be protected on the secondary circuit, according to the
transformer dimensions and the effective load of all connected devices:
Always protect the 24VAC conductor (system potential),
Additionally protect the conductor (system zero) where required.
CAUTION
Protection of the 24VDC Supply Voltage
24VDC power supplies must be short-circuit proof or have an internal
microfuse.
Local regulations must be observed.
CAUTION
Protection of Mains Voltage
Transformers/24VDC power supplies must be protected on the primary
circuit using a control cabinet fuse.
CAUTION
Power over Ethernet (PoE)
LPAD-7 Touch Panels require a PoE Class 1 power supply (max. 12W),
which must be compliant to IEEE 802.3at-2009.
For the power supply of the PoE switches observe the manufacturer’s
specifications.
CAUTION
Attention to External Voltages
Any kind of introduction or spreading of dangerous voltages onto the low-
voltage circuits of the system (e.g. due to incorrect wiring) must be avoided
at any circumstance and represents an immediate life danger or can lead to
the entire or partial destruction of the building automation system.
