Important Safeguards
!
When using electrical equipment, basic safety precautions should
always be followed including the following:
—
To avoid fire, shock, or death, turn off power
at circuit breaker or fuse
and test
that power is off before wiring, servicing fixture or changing lamps.
—
To be installed and/or used in accordance with appropriate electrical codes and
regulations.
—
If you are not sure about any part of these instructions, consult an electrician.
—
This device can be wired either as a Class 1 or Class 2 wiring device. Be sure to
install in the same manner as the other devices on the DALI loop. When in doubt,
install as a Class 1 wiring device. Consult local building codes and regulations for
proper low-voltage installation.

Description
The OSRAM TW-DL-12V/110mA-Power Pack provides power to a DALI network. A single power pack can provide 110mA of power, which would be used by a combina-
tion of DALI compatible controllers and ballasts.
Please refer to LMS168 for details on how many wallstations/LED Drivers can be powered with this power pack.
If more current is required, one other OSRAM power pack can be added in parallel to a single DALI network, which would bring the total current supply to 220mA.
Please note that the total current supply on a DALI loop cannot exceed 250mA. The power pack is mounted directly to a junction box
(refer to Figure 1)
. The unit must
be installed in a properly grounded metal 4" (10.16 cm) outlet box, a minimum of 2 1/8" (5.39 cm) deep. All Class 2 (low-voltage) wiring must be contained within the
Class 2 compartment (the area enclosed by the isolation barrier –
refer to Figure 2
). All Class 1 (high-voltage) wiring must be contained within the Class 1 compartment
(refer to Figure 2)
. Install or rearrange circuit wiring so all high-voltage circuit and load wires enter the box from one side, and all low-voltage wires enter from the other.
