DALI gateway Plus
Connecting the device
Control cable: appropriate type, cross-section and routing for the specifications for 250 V
cables. DALI and mains voltage wires can be run together in a cable, e.g. NYM 5x1.5 mm².
■ The DALI control voltage is a functional extra-low voltage (FELV). When performing in-
stallation, perform the installation in such a way that when an area is disconnected the
lines carrying both the DALI and also the mains voltage are disconnected.
■ If multiple circuit breakers supply dangerous voltages to the device or load, couple the
miniature circuit breakers or label them with a warning, to ensure disconnection is guaran-
teed.
■ DALI participants from some manufacturers have expanded functions and can e.g. be
controlled via mains voltage on the DALI connection. When existing DALI installations are
refitted, remove all corresponding operator controls.
■ Connect device as shown in the connection example (Figure 2).

■ Attach the cover cap to the bus cable connection as protection against hazardous
voltages.
If the display (8) shows
Er
(error), an installation fault occurred that causes mains voltage
to reach the DALI cable. In this case disconnect the device and and the DALI devices
from mains voltage and disconnect bus voltage. Correct installation.
Operation in emergency lighting systems
The device can be used in decentrally-powered or in centrally-powered emergency lighting sys-
tems.
In decentrally-powered emergency light systems, emergency luminaires with individual batteries
and special DALI devices are used.
Observe the number of DALI devices in the emergency luminaires used.
The statutory and standard specifications vary from country to country. In any event, the
user / technical planner must check whether the specific specifications are observed.
Emergency lighting systems with a central safety supply are required in buildings larger than
2000 m². Depending on the scope of functions of the system, only the emergency luminaires
are supplied by the central safety supply (figure 4), or the KNX system and DALI gateway are
also supplied (figure 5). In the latter case, in emergency operation, the DALI gateway can trans-
mit the appropriate fault messages to a central system and other DALI gateways in the system.
