Overview power connections X16 – X36
Fig. 11: Power connections X16 – X36
Please consider the following aspects:
Connecting the lines: The Slave module has only to be connected to power supply including
PE on X100. The Master module has to be connected to power supply and PE on X100, and
additionally to all bus-, control- and lamp cables.
Voltage balancing: on installing several ELCs the ballasts have to be equally distributed on all
phases (e.g. 1
st
ballast L1/L2, 2
nd
ballast L2/L3, 3
rd
ballast L3/L1 etc.).
Protective conductors: to ground the ballast it is strongly recommended to connect to X100 at
least one PE-line with a cross section of 10mm² or two PE-lines with nominal cross section of
the mains supply lines.
Cut-Out and loop impedance: The installation of an automatic cut-out is required for line
protection. It is necessary to check the loop impedance afterwards.
Using an RCD: if a RCD is required we recommend a RCD type B. When using a RCD consider
the leakage current given in chapter 6.
Shielding:
The lamp feeder cable shielding must be connected to the ELC at the designated
shield clamp, see paragraph 3.2.9.
If desired, the shielding can also be connected to the lamp unit.
