AC power and data connection
Warning! Read ‘Safety information’ on page 7 before installing the fixture.
For protec
tion from electric shock, the power input to the Junction Box must be
grounded (earthed). The power distribution circuit must be equipped with a fuse or
circuit breaker and ground-fault (earth-fault) protection.
AC power and control data are connected to the Junction Box. Up to 32 VDO Atomic Dot fixtures
may then be connected in a daisy chain to each junction box using a hybrid PDE cable which
carries both power and data.
Safety limits for connecting devices
As the fixtures are connected in a chain, there is a limit to how many fixtures you can link together
and how far apart they can be.
x Maximum of 32 fixtures connected in a chain.
x Total maximum length of PDE cable between the Junction Box and the last fixture is
dependent on the protocol being used – 300m for DMX-512 and 90m for Art-Net, sACN or
P3.
x Install the sealing cap on the thru connector of the last fixture in the chain.
AC power connection to Junction Box
Do not use an external dimming system to supply power to the Junction Box and fixtures, as this
may cause damage to the fixtures that is not covered by the product warranty.
Socket outlets or external power switches used to supply the system with power must be located
near the system and easily accessible so that the system can easily be disconnected from power.
If you install a power plug on the power cable, install a grounding type (earthed) plug with integral
cable grip that is suitable for your local mains voltage at a current of 16A. Follow the plug
manufacturer’s instructions and connect the wires in the power cable as shown in this table:
Live or L Neutral or N
Earth, Ground or
US system
Black White Green
EU system
Brown Blue Yellow/green
The fixture has an auto-ranging power supply that accepts AC mains power at 100-240 V at 50/60
Hz. Do not apply AC mains power at any other voltage or frequency to the fixture.
Data connection to Junction Box
The VDO Atomic Dot fixtures may be controlled by DMX512, Art-Net, sACN, or Martin P3 protocol.
The data connection is made to the junction box and then linked to the fixtures via the PDE
connections.
