3.2.3 Overview power connections X4 – X8
Fig. 6: Power connection X4-X8
Fig. 6 shows the electrical wiring. Please consider the following aspects:
Voltage balancing: on installing several ELCs the ballasts have to be equally distributed on all
phases (e.g. 1st ballast L1/L2, 2nd ballast L2/L3, 3rd 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.
