2.4 General installation instructions
2.4.1 Safety instructions
— Please read these operating instructions carefully before installing and using the OSRAM BT Control devices. This is
the only way to ensure that you use the equipment safely and correctly. Keep these operating instructions in a safe
place for future reference. You should make sure that everyone who uses OSRAM BT Control devices has read these
operating instructions.
— Apart from the explicitly mentioned components, no further control units may be connected to the DALI lines.
— OSRAM BT Control devices may only be installed by qualified personnel who have been appropriately trained and who
have the relevant authority. The installation personnel must be familiar with the operating instructions. Power must be
switched off before any work is undertaken on the system.
— OSRAM BT Control devices units are especially designed for installation within luminaries (DALI ECO BT) or flush-mounted
boxes (DALI ACU BT). An independent installation of DALI ECO BT is only allowed in combination with the mounting kit
ECO CI Kit.
— The relevant safety and accident prevention regulations must be observed.
— If the control cables, sensor cables or the switch and/or the synchronization input is wired with external voltage,
particularly with a mains voltage of 230 V, the unit may be destroyed.
2.4.2 Wiring instructions
DALI, sensor and pushbutton wires must never be connected or applied with mains voltage. Before connecting any new
components, the mains supply of the control unit has to be switched off. After switching on the mains supply, the control
unit automatically detects all connected components. The plug-and-play principle is valid, which means that there is no
need to manually configure components to ensure a proper operation.
Wiring of the DALI connection
The DALI standard requires basic insulation against mains. To fulfill the safety regulations, an additional insulation against
mains is required. For DALI wiring, a cable suitable for line voltage is mandatory (even if in normal condition only 17 V
DC
will be supplied). The terminals of the BT Control products are suitable for wire sections of 0.5
mm² to 2.5 mm². In order to
not reduce the maximum cable length of a DALI installation (300
m), a wire section of at least 1.5 mm² is recommended.
DALI wires can be run with line voltage in the same cable. This means that, for example, an NYM-J 5 x 1.5 sheathed cable
(where two wires are used for the DALI communication) is suitable. For DALI wiring, the usage of control and data cables
such as LIYY or bell wire cables such as YR or comparable products are not allowed and a reliable operation may not be
ensured.
Wiring of directly connected pushbuttons
For the wiring of directly connected pushbuttons, a cable suitable for line voltage has to be used. In principle, the pushbutton
wires can be run in the same cable as the mains supply.
In case of longer cable lengths, or in case of incoupling disturbances that lead to a measurable AC disturbance voltage on
the pushbutton wires, which may therefore lead to malfunctions, the usage of a DALI pushbutton coupler (or at least a
separate pushbutton connection cable) is recommended.
The pushbutton wires have to be run locally separated from lamp or LED supply wires. Parallel-running lamp or LED supply
wires may have a negative impact on the pushbutton function.
Wherever possible, crossing of pushbutton wires with lamp or LED supply wires should be at right angles to minimize
capacitive coupling of disturbance signals.
Usage of small-signal or low-voltage pushbuttons is allowed as long as they provide a sufficient isolation (isolation voltage
of at least 1500 V).
Interfaces (wired and wireless) Maximum value
DALI control interface Max. total wire length: 300 m
Pushbutton interface Max. total wire length: 50 m
(PB2 = 5 m for DALI ECO BT RTC only)
Wireless Bluetooth interface Max. connectivity range: 15 m
